The best robot vacuum cleaner: comparison table
Having a cleaning lady without having to hire anyone, without having to give house keys to a stranger and without having to pay a salary? You can, thanks to the new robot vacuum cleaners. This new technology, thanks to the advances of the last few years, is really making great strides. The first rudimentary models, in fact, were not very effective. But today, the robot vacuum cleaner market has been enriched with models that really do everything by themselves. Think that they can map your home, and also receive impulses through an app from your mobile phone.
A robotic vacuum is a small household appliance that runs on battery power. It moves over your floors (and rugs, carpets, etc.) and does the job of a vacuum cleaner. It reaches all points of your home, avoids obstacles, and makes you a perfectly clean floor. Some can be scheduled daily and / or weekly.
There is nothing better than returning from work after a tiring day and finding the floor already perfectly clean. But do these robots really work? How much do they cost? How often should the dust container be emptied? To these, and many other questions, we will try to answer in this article and in the individual reviews, giving you all the elements to choose the best robot vacuum cleaner.
How does a robot vacuum cleaner work?
Generally, the robot hoover has a cylindrical shape, and is very low so that it can also enter under beds or sofas and armchairs. Its navigation system emits infrared rays that allow it to recognize and avoid obstacles. The more advanced models recognize the stairs, and for some it is possible to set “virtual walls”, so that they clean only a part of the room or house. Typically, the models on the market today have a function that allows them to return to the base and recharge before the battery runs out.
As a vacuum cleaner, they work like normal ones, thanks to a turbine that causes air to suck inward. Generally they are equipped with brushes which also partially provide the services of a polisher, for better cleaning. Finally, some models may have sensors to recognize the type of surface: polished floor, parquet, carpet, rugs, etc.
How to choose a robot hoover
It is a category in continuous evolution, with prices that can vary in a very wide range, just think that from the cheapest to the most expensive model, the difference can even be 10 times! This is mainly due to the investments in research and development necessary to keep up with the competition, since robotic vacuum cleaners are constantly evolving and becoming increasingly intelligent and effective. Let’s see together what are the fundamental characteristics of these appliances, those that will make us choose the model that best suits our needs and expectations.
It is a very difficult choice because there are many factors to consider, and at the moment there is no model that excels in everything. Below we have a detailed guide, but also a very long one, for those who want only juice, here is a short version:
- choose a model with intelligent navigation system: the best is the laser one, which also works in the dark; then there is the visual navigation (with camera / video camera), good but needs light, and then there are the random algorithms, which do not guarantee 100% coverage of the floor;
- choose a model with the dimensions (diameter and height) that best suit your home: the robot must be able to pass between the legs of the chairs and under the furniture;
- choose a model with silicone roller brushes, those with bristles are difficult to clean because hair and hair get tangled;
- choose a model that has good autonomy, or that has the function of recharging and resuming cleaning from where it left off;
- save on unnecessary functions: the 2 in 1 function (robot vacuum cleaner and scrubber with damp cloth) is not suitable for you if you have high cleaning standards. In this case, better a real floor cleaning robot, to be operated after the suction. Even the accessories for virtual walls (which delimit the areas to be cleaned) are now becoming extinct, replaced by simple functions present in smartphone applications;
- consider that models with Wi-Fi connectivity can receive updates that improve the functions or add others.
The navigation system of the robot vacuum cleaner
The navigation system is, in our opinion, the most important factor to consider when choosing a robot hoover. In fact, it gives rise to large price differences, but also to huge differences in efficiency and effectiveness. The navigation system is what will make you say you made a good purchase or a bad purchase. It is a complex and delicate topic, with different facets, but let’s try to clarify schematically:
Step detection sensor
This sensor prevents the robot from falling off the steps. It is now present on all models. It is a very useful sensor because it allows not only to avoid damage to the appliance, but also to clean surfaces other than the floor and suspended: for example, the upper part of cabinets and shelves, or tables and other tops of various furniture. Obviously, the sensor must work well and not miss a shot. If you try to clean high surfaces from the ground, it is always good to be present and ready to avoid disastrous falls.
Obstacle detection sensors
Not all robots have sensors for obstacle detection. Some quite simply hit walls, furniture, table legs and chairs with their cushioned front. When this happens, they change direction. It is a simple system, but not very suitable for those who, for example, have fine furniture or antiques. Even if the impact is well cushioned, in the long run all these blows can cause damage.
Other models, on the other hand, have infrared sensors that detect obstacles, and behave in two possible ways: some slow down before the obstacle and hit it, but at a reduced speed that combines with the shock absorber to create a contact without damage; others, however, do not touch the obstacle but turn immediately before reaching it.
Even in the presence of sensors, operation is not always guaranteed: it is easy for infrared rays to detect a solid wall, less easy to detect the leg of a chair or table. It is therefore a good idea to try to understand how many sensors the robot vacuum cleaner has: the more there are, the greater the visual coverage and the effectiveness of the system. Sometimes, it is difficult to understand why one model costs more than the other: the number of sensors is one of the hidden reasons that makes us confused, but it is a more than valid reason that justifies the higher price.
The sequence of movement
This factor is the most important when choosing a robot vacuum cleaner, and also that which sets a well-defined boundary between the “good” product and the “bad” product. The robot hoover is a new product, unknown to many, and most people buy it with expectations, without first finding out what they can and cannot do. Most of the complaints come precisely from this aspect: how it moves around the house.
Robot vacuum cleaner with random movement
The less performing models have pre-set random movement sequences, which allow you to cover most of the surface. Just to give an example, there are robots that move in a zigzag pattern for a certain period of time, then proceed in spiral movements, and finally move along the walls, and then start again. In this series of random movements, they can pass over and over again on the same point, perhaps leaving out others or making a single passage.
This method of movement also means that the robot will move from room to room in an equally random way, simply because it finds the door in its path. Always casually, for example, he can spend his time for 80% in one room, and maybe make a single short passage in another, or not find it at all. Robots with this simple navigation system tend, for example, to spend a lot of time in the corridors connecting rooms, where narrow walls cause many changes of direction.
Semi-random robot vacuum cleaner
The mid-range models also have random movement sequences, which however respond to a probabilistic algorithm. This means that there are as many movements as possible (for example: U-turn) and also that, thanks to infrared sensors, the robot can adapt the movements along the way. The ultimate goal is to cover as much of the surface as possible, and there are models that guarantee up to 98% coverage.
Even these models, however, do not guarantee total coverage of the apartment, and can spend most of the time in one or more rooms, and little or nothing in the others. Obviously, if the aim is to have a clean house, we are concerned that one room is very clean and another is very little. Of course, if scheduled cleaning happens every day, the odds are to our advantage: if it’s not today, the room will be cleaned better tomorrow.
Some models with Wi-fi connectivity and smartphone application are able to memorize what they did during the cleaning cycle, providing the user with a report that helps to understand which areas have not been cleaned to perfection.
Robot vacuum cleaner with mapping of the apartment plan
The more advanced, and more expensive, models can understand how your home is laid out and act accordingly. These models clean 100% of the floor, with an efficient sequence reminiscent of cutting grass on a sports field. They go back and forth, changing lanes, so to speak. And they pass from room to room. Clearly this method also allows you to better use the battery, and to have a total and uniform cleaning (if the battery lasts long enough for the surface of your home).
Here is a short video that explains well how visual navigation works, just like the Pacman video game!
Our advice is to choose a model with this function, because the difference in performance is enormous. However, everything depends on your needs, and following the article we dedicate a large section to the analysis of particular cases, where the choice can also be different.
Now, the mapping can take place in two ways: either thanks to a video camera (such as for the iRobot Roomba, ILIFE, Samsung and Dyson models, and in this case we talk about visual navigation, or through a laser scan, as happens at example for Xiaomi and Neato Robotics. This second mode is more accurate. In fact, in visual navigation the camera sees how large the room is looking towards the ceiling, then the sensors will adapt the path according to obstacles. The laser scan, on the other hand , immediately sees the obstacles and plans the entire route from the beginning.
The other important difference is that laser scanning also works in the dark, while visual navigation needs light. If you want to clean while you are at work, clearly a system that works even in the dark is necessary.
What if the battery doesn’t last long enough for the surface of my house? No problem, as long as you choose a model that also has an additional function: the ability to return to the base, recharge, and resume cleaning exactly from where it left off. This is the best solution for those with large surface houses.
Normally, mapping is done every time the robot starts cleaning, but there are models that can also store up to 10 different house plants. These appliances can be useful to those who have a house on several levels, but it is not necessary: in fact, if the map is made every time the cleaning starts, just move the robot to another level and this will perfectly clean creating the map of that level, so paying much more to have this feature is not recommended.
At the end of this long explanation about the movement sequences, we point out that some models of robot hoovers are equipped with a remote control and have movement sequences that can be set manually: for example, you want the robot to go in a zigzag pattern, or you want that this follows the contours of the room. Or you want to drive it entirely, telling it where to go.
Samsung robotic vacuum cleaners have a remote control that can be aimed at the floor, telling the robot to clean at that point. These are useful functions to go over some parts, or to intervene where something has fallen (example: cleaning the kitchen after meals). The main purpose for which you buy a robot vacuum cleaner, however, is not this: usually you do it because you want it to clean in our place while we are not at home or while we do something else that we like best, and not to use it manually.
Here is a video of Samsung’s Point Cleaning feature:
When you entrust the cleaning of the house to a robot vacuum cleaner, it is good to prepare it a little. In fact, robots do not like obstacles, like electrical cables left on the floor. However, each robot has a certain ability to overcome obstacles: not much, in truth, but different from model to model. This ability is also needed for carpet cleaning. Depending on the model, it will be possible to climb on carpets (or overcome obstacles) that have a height ranging from 1 cm to 2 cm approximately.
The difference between the models is given by the wheels (larger, smaller, of soft rubber or hard plastic, with or without tread / grooves) and also by the power of the engine. Power that, on the other hand, must take into account the battery: the manufacturers must therefore find the right compromise, because greater power means better overcoming obstacles but also less autonomy. Another factor that helps in climbing is the height from the ground, and the diameter of the wheels: but even here, the right compromise must be found, because one of the qualities of the robot is to get underneath beds, bedside tables, armchairs and sofas, and therefore increasing the height would reduce this ability.
Some Samsung robotic vacuum cleaners are equipped with a lifting lever that operates in the event of obstacles. An intelligent solution that does not consume a lot of energy.
Robot vacuum cleaner cleaning system
A robot hoover can give more or less substantial help in cleaning the house. This mainly depends on the cleaning system, but also on the suction power. Regarding pure power, this can never be that of a traditional vacuum cleaner, for two main reasons: the first is that it is a battery-powered appliance, so too high a power would drastically decrease the autonomy.
The other is the limited space available for the motor housing, which must necessarily be small. In this regard, some robot models have a variable power, which adjusts to the maximum value only in the case of difficult surfaces (such as carpets), or when the sensors detect a higher quantity of dirt, thus avoiding waste of energy.
The cleaning system, on the other hand, in many cases manages to compensate for the low suction power by using a small suction mouth and bringing the particles to be sucked as close as possible to the motor. The suction, depending on the models, can be helped by devices that:
- they sweep the dust by directing it under the suction mouth
- they lift it
- chop the larger particles
So let’s go in order.
Side rotating brushes
Almost all models have one or two side brushes, which rotate towards the inside of the machine. These are used to collect dust from the edges and along the skirting boards, moving it towards the center of the appliance, where the suction mouth is located. Until recently, this device was only installed on circular-shaped robots to collect dust from otherwise unreachable corners. Other brands, which produced appliances with a flat front, did not have this possibility. Lately, however, and by popular demand from the public, this effective system has been adopted a bit by all the manufacturers, regardless of the shape of the robot. These brushes are light and delicate and require periodic replacement.
Rollers to lift and chop
Some robots are also equipped with a roller in the central part, which is in contact with the floor and rotates, raising the dirt and directing it towards the cyclone engine. These rollers can be with bristles, or entirely in silicone with protruding feet or spatulas.
Roomba robotic vacuum cleaners, in particular, have two rollers, which rotate in opposite directions: one that raises the dust, the other that chops it, useful for example if, after breakfast, pieces of corn flakes or other have fallen into it similar material. To date, this is the best cleaning system in its category.
Other cleaning devices
It should be mentioned that some Samsung robot vacuum cleaners have a self-propelled spatula which is activated when the robot is in contact with the walls, and which captures the dirt attached to the baseboard. The system is ingenious, but doesn’t seem to work very well, judging from user reviews.
Robot vacuum cleaner and floor cleaner
We have robots that only perform the suction function, and others that, at the same time, also pass a wet or damp cloth on the floor: they are therefore 2 in 1 robots, vacuum cleaners and floor cleaners. These appliances can be used either without a cloth, only with the vacuum cleaner function, or with a damp cloth. They have a water tank that serves to moisten the cloth constantly.
The advantage of wiping a damp cloth after suction is that it is “fixed”, so to speak, and will last longer. The disadvantage is that if the suction has not been perfect, the passage of the damp cloth will make things worse, mixing the remaining dirt and making subsequent removal more difficult. The robot vacuum cleaner and floor cleaner is suitable for completely smooth surfaces, such as parquet or marble, but not very much for tile floors with joints. Furthermore, it is not suitable for rugs and carpets.
This type of appliance differs from the actual floor cleaning robot, which does not have the function of a vacuum cleaner but does the job of moping for you. For these products we will have a special category. Instead, we decided to put robotic vacuum cleaners and floor cleaners here, as many users mainly use them as vacuum cleaners.
Functions of the robot vacuum cleaner
Let’s see what other functions can be found in a robot vacuum cleaner.
The charging base is not present in the most basic models, but has now become almost the standard. And with it, the ability to return to the base before the battery runs out, to begin a charging cycle. This useful function makes your robot vacuum cleaner always ready for use. But be careful: it doesn’t always work. Especially the models that have random or semi-random navigation systems, sometimes the robot finds it difficult to find the base, especially when it is in a room away from the base. So it can happen to find it unloaded anywhere in the house.
The models with mapping, however, always know where they are relative to the base, and therefore they never struggle to return (another valid reason to prefer them).
For some robots, it is possible to specify a schedule that performs cleaning at a predetermined time of day. Usually, the time can be different according to the day of the week. You certainly don’t want the process to start too early on Sunday.
Some models connect to the home Wi-Fi network, and can be controlled from your smartphone. In this case, the functions can be the most varied: from programming done directly on the app, to manual ignition, perhaps from your office. Some apps after each cleaning session show a report on the work performed, useful for models with semi-random navigation. In fact, from the report it is possible to see the path followed by the robot, and if it has left out some area. However, the report is also useful for models with room mapping, to see if some hitch has happened.
The applications, always available for Android and iOS, are often rudimentary, but over time they should be updated and work better. Connectivity gives manufacturers the opportunity to update the robot vacuum cleaner software, perhaps adding some functionality. It doesn’t happen very often, but in theory it’s possible.
Maintenance of a robot vacuum cleaner
When thinking about buying a robot vacuum cleaner, the idea is to make it work for us. It is therefore important that maintenance is not too expensive, otherwise we risk having to work for him.
After each use, the dust container should be emptied. It is therefore important that it can be easily removed, and it is also important that it is large enough. Many appliances stop and beep when the tank is full. Others return to the charging base and stop cleaning. Still others, however, continue to work, but if the tank is full you risk seeing the dust spewed out. This happens with some ILIFE models of vacuum cleaners.
Unfortunately, the robot tanks, due to the small size of the device, are always not very large. It is difficult to reach one liter, and the smallest can only hold 0.2 liters. Depending on the surface to be cleaned, you must choose a robot that has a tank that cannot fill the tank before a complete cleaning cycle. In this regard it also helps that cleaning is done every day.
The filter, usually washable, must also be cleaned after each cycle. Usually, it is vacuumed with another vacuum cleaner, and periodically washed with mild soap and water, taking care to dry it perfectly before the next use. After a certain period, the filter must be replaced.
Finally, always after each cleaning, it is necessary to clean the roller (or rollers) that make up the cleaning system, which is usually removable. There is a big difference between bristle rollers and silicone rollers in terms of maintenance. The former, in fact, tend to form tangles of hair and hair and are difficult to clean: gloves, scissors and patience are needed. The silicone rollers, on the other hand, do not form tangles and are the favorites, so consider this aspect well in your choice.
Another operation to be performed, but not every day, is to clean the wheels, making sure to remove residual dust so that they turn freely and perfectly.
The battery of the robot vacuum cleaner
The battery is the heart of a robot vacuum cleaner. To evaluate the quality of a battery, there are three main criteria: autonomy, charging time and duration of its life. In this case, the weight is of little interest to us, as the robot hoover does not need to be manually operated. The other aspects, however, are crucial for the choice. If you need to clean a small room, you can always opt for a model with limited autonomy. Conversely, for a larger house, it will be necessary to have greater autonomy.
Nowadays, the importance of this factor is more limited than in the past: in fact, almost all robotic vacuums have a charging base, and have the ability to return to the base on their own before the battery runs out, proceeding to a recharge. Not everyone, however, starts to clean autonomously when the battery is charged: only the most advanced models start cleaning again from where they left off; others do it, but starting the process all over again, and others do not do it at all, and are waiting for new orders. Except for the first case, therefore, it is important that the autonomy is sufficient to clean the whole house in a single session.
Even if the battery affects the price, spending little sometimes does not pay. If the battery is of poor quality, regardless of autonomy and charging time, it will also have a short life. Autonomy will tend to drop over time, and charging times will tend to lengthen, making your robot vacuum cleaner useless. Remember, too, never to choose batteries that suffer from the memory effect, such as Ni-Mh batteries. In fact, these tend to lose power as they are discharged, with the unfortunate consequence that some parts of the house will be cleaned with less accuracy. The cheaper models have this type of battery, while the best models have the Li-Ion battery installed.
Shape, dimensions and height of the robot vacuum cleaner
There are two possible forms at the moment. The most classic is the rounded shape, while some brands use a U-shape, with a flat front, such as Neato Robotics or Samsung. Although the flat shape can give the impression of reaching the corners better, in reality it is not so: it is the side brushes that, with their rotation, collect the dust from edges and corners.
The dimensions are more or less important depending on the holes you have in your home, such as narrow spaces between furniture and walls, or chairs with more or less narrow legs. Normally the diameter of a robot vacuum cleaner ranges from 30 to 36 cm.
Height is another important aspect, it generally ranges from 7 cm to 10 cm, and this factor determines the robot’s ability to pass under beds, sofas and armchairs.
Choose the model that best suits you, but also consider that smaller dimensions, both in diameter and height, often also mean smaller dust containers, or less powerful motors.
Some robot vacuum cleaners have a battery-operated device as an accessory that creates, via infrared rays, virtual walls up to about 3 meters long, which the appliance will not pass through during cleaning. It serves, in practice, to “virtually” close any openings that you may have at home. Some Roomba robotic vacuum cleaners have this accessory but with a double function: virtual wall but also “forbidden area”: a circular area, with a diameter of about 1.2 meters, which the robot will avoid cleaning. This is useful when there are objects that, if moved, could create problems. The classic example is the dog bowl when it is full of water.
Many brands of robot vacuum cleaners are quite unknown, as they are companies that have specialized in this product, and that do not sell anything else. Furthermore, Europe in general is far behind in this category of products. Even giants such as Philips perhaps have only one model, and with rather rudimentary characteristics.
Below we have a rundown of market leading brands, with strengths and weaknesses, also summarized in the following table:

Roomba robotic vacuum cleaners are the most famous on the UK market, having a good distribution in the consumer electronics stores. They are Made in the USA, and have a wide choice, with numbered series that currently range from 600 (the most basic series) to 900 (the most advanced series).
The models are quite expensive, difficult to spend less than 300 pounds for a Roomba. On the other hand, they have the best cleaning system on the market, also thanks to the automatic detection of the particularly dirty areas in which they pass several times. To have a model with mapping you have to go to the 900 series, spending much more. The system is entrusted to visual navigation, with some flaws.
Paying more, sometimes, rewards us: iRobot offers a 24-hour support service, highly appreciated also by British customers.
The main competitor of iRobot Roomba, and always American, is Neato Robotics, with its Botvac. It is a series of robots with an excellent navigation system, and all models have the function of mapping rooms (probably the best in this respect, with laser scanning). The Botvac are immediately recognizable by their U-shape, with the flat front. Botvacs are also concentrated in the high price range. However, the cleaning system is not the best, and loses comparison with other brands.
The Korean company is certainly not unknown. Samsung robotic vacuum cleaners are highly technological, have the function of mapping and also innovative solutions for the use of the remote control and also for the cleaning system. They are very expensive and many of those who have tried them have not been satisfied with the quality of the visual navigation software. The features are there, but they don’t work as they should. We have to think that Samsung will fix it with updates, but paying a high amount for something that is not working perfectly at the moment is not exactly a good idea.
This Hong Kong-based firm sells directly to Amazon, and is the one that receives the best reviews for its products. Its strength? The price! For the same characteristics with the three brands mentioned above, ILIFE sells its robot vacuum cleaners at a third of the price, or even less. There are both models with mapping (visual navigation) and without, and all have very compact dimensions and are very thin.
Few complain of their purchase, partly aware that the price is much lower than the competition. Many reviews, in fact, contain phrases similar to “… for what I paid for it …”. So what’s the downside? There is no assistance in the UK so, to date, it is not possible to repair a faulty ILIFE robot vacuum cleaner. However, by buying from their store on Amazon, you enjoy the right of return within 30 days, as well as the two-year warranty which, however, consists of return and refund, as the repair is not provided. In addition, the suction power is limited.
Another Chinese company, already a smartphone manufacturer, which has launched in this market is Xiaomi. Xiaomi robotic vacuum cleaners are all white, quite massive, and all have the function of mapping the house with laser scanning. They also do a great job with the cleaning system which proves to be efficient, not up to iRobot Roomba but still good. Finding detailed information on these models is very difficult, the Xiaomi website does not help.
As for the other Chinese company ILIFE, Xiaomi also has no assistance centers in the UK. For this, it is very important to buy on Amazon, to enjoy its guarantee from A to Z. In this way, if a fault occurs, you can ask for a refund. Alternatively, it is possible to buy robots on Chinese stores, perhaps saving a few pounds, but if a fault happens then you will be in trouble.
Some traditional brands are starting to understand the potential of this market and have started offering their robot vacuum cleaners. Among these, the aforementioned Philips, Severin, and also the Italian Ariete. It would be expected that Dyson, the most famous English company in the world for its technological vacuum cleaners, would have launched headlong into the market. Instead, in its line there is only one model of robot vacuum cleaner, powerful but not particularly advertised, as are its wireless electric brooms.
Alternatives to the robot vacuum cleaner
The robot vacuum cleaner is not the only automatic tool available for maintaining a clean home. There are, in fact, other appliances that can clean your floors independently.
The robotic dust catcher
The robotic dust catcher it moves independently and avoids obstacles in the room, but has no dust suction. Instead, it runs a dust catcher over the floor. It is usually much cheaper than a robot vacuum cleaner, and has no special functions. This appliance can be suitable for those with uniform hard surface floors, such as stoneware, marble or parquet, but not suitable for those with rugs or other fabric surfaces.
The floor cleaning robot
It is a particular type of robotic vacuum, which is also equipped with a water tank: it therefore combines the suction function with the washing function. This appliance is also less versatile than the normal robot hoover, as it is not suitable for rugs and carpets and is not particularly recommended for parquet. It is a rather expensive appliance, as it adds a function to the normal robot vacuum cleaner. Other appliances, on the other hand, specialize only in washing, without the suction function.
The price of a robot hoover
The price of a robot vacuum cleaner is quite high, and this depends on the technology used. Even the one without additional functions must still have sensors to get around obstacles, and this affects the price. Some functions are also almost essential, such as returning to the base for recharging. The price range goes from about 200 pounds up to models that touch the 1000 pounds. Is it money well spent? Compared to paying a person to clean your home periodically, definitely yes. Of course, the robotic vacuum can only clean floors. It cannot dust furniture or shelves, this one cannot.
Being a new product with advanced technology, the robot vacuum cleaner can generate some questions. We try here to answer the most frequent ones.
How do robotic vacuum cleaners behave when cleaning corners?
Some robots have a rotating side brush or even two (one on each side) that channels dirt into the suction path. In a normal room (where the angles are at 90 degrees) there are no big problems, at most a few triangles of a few square cm can remain where the robot cannot reach. If you have acute angles there may be more problems.
My house has several rooms, will a robot vacuum cleaner clean every single room every day?
The robot works as long as the battery lasts, after which it returns to the base for charging (in models that have this function). The part of the house that will be cleaned depends on the navigation system, the tank capacity and the battery life. The robot that has a random or semi-random navigation system works best in open spaces, worse in houses of many rooms separated by normal doors. The first room in which the robot starts cleaning will always be sucked in, but where it will go next is random and there is no guarantee that it will reach all parts of the house. In practice, if it is near an open door, it will probably change rooms most of the time, but it is not guaranteed.
This is why the mapping system is so important. Furthermore, it is necessary that the autonomy is sufficient to cover the surface of your home, unless there is the function of recharging and resuming the cleaning from the point where it was interrupted, this also present only in robots (but not in all) that map the rooms.
So shouldn’t I buy a robot without mapping if I have multiple rooms to clean?
It depends on how much human interaction you are willing to give. If you have a limited budget and it doesn’t bother you to take the robot manually and put it in the room where you want it to be cleaned, then any robot vacuum cleaner can be for you. But if you want a “set and forget” approach, you probably have to spend more and get a floor plan mapping model. Such robots can break the house down into zones and cover every inch of the house efficiently.
Is it true that the robot cannot be used on different floors of a multi-storey house because the appliance can only store one floor?
False. The cheaper models, without mapping, never learn to memorize the plan of the apartment. This means that it doesn’t matter if you move them from one floor to another.
Among the models with integrated mapping, however, you will find robots that every time they perform a new cleaning cycle, they create a new map. In other words, these robotic vacuum cleaners do not save or archive the mapped areas, so moving it to a different floor of the house does not create problems.
Other more advanced models store up to 10 different maps, so they can easily be moved from floor to floor.
How can I clean an entire level with my robot vacuum cleaner?
Complete cleaning is guaranteed only with models that have the mapping function. They have a visual navigation and aspire more or less in a path made of straight lines, proceeding in lanes. If there are multiple rooms with doors and corridors, as in most houses, robots without this function will probably not be able to cover the entire surface and will have to be moved from room to room.
Will the robot climb over low obstacles and climb carpets?
It depends on the model but, most likely, it will. Unless the height difference between two areas is very significant (greater than one and a half centimeters), all current robots should overcome the obstacle without problems.
How loud are robotic vacuum cleaners while vacuuming?
First, the noise level depends on the type of surface you are vacuuming (more noise on hard surfaces, less noise on carpets and rugs). The differences between the models are not very significant, however they range from about 58 dB to 70 dB. Basically, they make noise, but much less than a traditional vacuum cleaner. Of course, they can’t be operated while sleeping, if that’s what you’re wondering.
Which robot model is best for these specific situations?
Hair and pets
Better to choose a brushless model with bristles, in which hairs and hair tangle making maintenance very difficult. Excellent silicone rollers, which avoid tangles.
Hard floors (parquet, tiles, marble, etc.)
All robots work well on hard surfaces. They are quite simple to vacuum, and therefore do not require the power that is required by rugs and carpets.
Carpets and rugs
The best model for carpets is the Roomba 981. Any robot will do a good job, but if you have a carpet type floor you want the top of the range, the 981 is the best solution.
Clean the house when I’m at work
If you intend to keep the blinds / shutters closed, do not choose a model with visual navigation. To operate in the dark, the robot needs laser scanning. Recommended brands: Xiaomi, Neato Robotics.
Study or house with one bedroom
When it comes to small and / or simple houses, any robot vacuum cleaner will give an excellent result, even those with a random cleaning scheme, zigzagging around the house to cover every inch. Mapped models are more efficient and use straight lines. Both methods will work, so you can go for a cheaper model.
House with two or more bedrooms
For such a house, we recommend a robot vacuum cleaner with mapping function of the house plant, because it is the only one able to guarantee complete and efficient cleaning.
Unfortunately, there is no robot that can suck two levels at once. The ability to climb stairs is too complex for robots with current technology. The only way is to move the robot manually from level to level.
The robot vacuum cleaner is an expensive appliance, but it gives a great help in the daily cleaning of your home, especially for those who have pets or suffer from allergies. Allows you to maintain a clean home effortlessly while at work or, why not, on vacation.
