1. Power
How well do the devices handle dust suction?First of all, any vacuum cleaner is bought for garbage collection, right? In this regard, its most important parameter is power. You do not want to face the fact that after cleaning, further steps are needed to achieve complete cleanliness?
Best of all, Midea and Roborock cope with their main task. They suck up dust with twice the force of any of the competitors! It is even surprising how the manufacturer managed to introduce such a powerful engine into his creation. The robot from Xiaomi also shows itself very well. But he copes with carpets much worse. Not to mention Tefal - this vacuum cleaner is best used exclusively on laminate, parquet or linoleum, like the other two devices.
Name | Power consumption | Suction power |
Midea M7 | 55 W | 55 W |
REDMOND RV-R650S | 22 W | 25 W |
Roborock S5 Max | 58 W | 58 W |
Tefal RG6871WH | 25 W | 25 W |
Xiaomi Mi Robot Vacuum Mop | 40 W | 40 W |
Like it or not, but any robot vacuum cleaner will still fight dust worse than its traditional counterpart. That is why it is recommended to use such a device on a daily basis - in this case, he will not have to deal with the accumulation of debris, and then you will definitely pay attention to an excellent result. At the same time, there will be no noticeable difference between the work of different models.
2. dust collector
How often do you empty the waste container?
We note right away that the device from Tefal should travel around the apartment every day. Only in this case you will not complain about the volume of its dust collector. The fact is that it is only 0.25 liters! Such a container simply does not fit any large garbage (at least in large volumes). It also makes you think ten times before buying such a robot if you keep a pet. If we talk about its competitors, then they have much more capacious containers, and therefore there are no special complaints about them.
Name | Dust container volume |
Midea M7 | 0.35 l |
REDMOND RV-R650S | 0.45 l |
Roborock S5 Max | 0.46 l |
Tefal RG6871WH | 0.25 l |
Xiaomi Mi Robot Vacuum Mop | 0.6 l |
Xiaomi has the most capacious dust collector. Practice shows that the container of a device from a Chinese manufacturer does not need to be emptied every day. If you do not keep pets, then this process will only be required once a week. Also, Redmond and Roborock can boast of a good volume of dust collector. It is also impossible not to note the fact that getting a container with garbage from a modern robot vacuum cleaner is very simple. Gone are the days when this process was inconvenient, and even risky - it was possible to damage some details. That is why problems will not arise even for very lazy people.

3. Comfort
Assessing the noise level and automatism
It is difficult to argue with the fact that robotic vacuum cleaners are much more convenient than their traditional counterparts. These devices are ready to work at a time when not a single member of the family is at home. To do this, it is enough to program the device to work on certain days of the week. This feature is available in all three models we have chosen. And the Xiaomi product offers much more opportunities, as it allows you to control yourself from your smartphone. In particular, the robot vacuum cleaner can thus send voice notifications. It also offers a choice of several pre-installed cleaning programs, including those related to washing the floor. But the main advantage of this model is the adequate construction of a map of the premises. In the future, this allows you to order the device to clean a specific room, for example, the kitchen, by pressing one button.
However, Roborock and Midea build the room map almost better. The fact is that they are equipped with a laser rangefinder. With it, the device ideally determines the distance to the nearest wall or some other obstacle. And these devices also support control from the application - no remote control is included with them. The programs turned out to be very similar - one gets the impression that they were created by the same developers. All the necessary functionality is present in them, there is nothing to complain about.
The Redmond robot vacuum cleaner also shows its best side. It can be controlled both from the bundled remote control (similar to the one that comes with Xiaomi TVs and smart set-top boxes) and from a smartphone. This device also builds a map of the room, and it also copes with this task perfectly. Many adjustments are available in the application, including changing the level of water supply when the tank is full.Not forgotten and voice alerts. Not to mention the suction power. It should be noted that even when choosing the highest value, such vacuum cleaners are not particularly annoying with their noise - measurements in the immediate vicinity show from 62 to 70 dB.
Finally, we note that Xiaomi and Redmond robot vacuum cleaners support control through the Alice voice assistant. In the case of the first - only when purchasing the so-called global version. It is she who is sold in our online stores and large retail chains.

4. Wet cleaning
How wet does the floor get?
The robotic vacuum cleaners included in our comparison are able to wipe the floor. To do this, they use water poured into a special container. But you need to understand that its volume is approximately one glass. Needless to say, this is barely enough for just one room? Also, you should not rely on the fact that the device will cope with pollution from a week ago. An even more annoying limitation is the round shape of the device. Because of it, none of the vacuum cleaners is able to wipe the floor along the baseboard. In a word, when buying a robot vacuum cleaner, you should be aware that you still have to sometimes use a rag.
Alas, tests show that one should not count on an ideal result. Above we have already talked about the main reasons. Next, we note another, not the most obvious. You will simply forget about filling the corresponding container. And none of the vacuum cleaners reminds of this.And even if someone could do it ... Let's remember that most often the robot vacuum cleaner works in your absence. It is unlikely that you would spend time filling the container before you go to work. So it turns out that, at best, wet cleaning will be carried out only on one of the weekends. And even then only if you remember that it would be time to fill the tank of the robot vacuum cleaner with water.
Our advice to you: if wet cleaning is the most important function for you, then consider buying a floor polisher. It is these devices that are used by owners of shops and other large premises. But in this case, you will have to forget about collecting any large garbage.

How long can cleaning take?If we talk about traditional vacuum cleaners, they are connected to the mains. Cleaning with their help can last as long as you like - even a whole day. But this is what you have to do. And who wants to spend their strength if, for example, they were previously spent at work? That is why robotic vacuum cleaners are in increasing demand every year.
Name | Battery capacity | Working time | Charging time |
Midea M7 | 5200 mAh | 180 min | 150 min |
REDMOND RV-R650S | 2600 mAh | 140 min | 330 min |
Roborock S5 Max | 5200 mAh | 180 min | 180 min |
Tefal RG6871WH | 2500 mAh | 150 min | 360 min |
Xiaomi Mi Robot Vacuum Mop | 2400 mAh | 90 min | 120 min |
The first robotic vacuum cleaners received a low-capacity battery, which was also made using nickel-cupronickel technology. Fortunately, the situation has now changed.All models we have selected have a long-lasting lithium-ion battery that can be recharged at any time. Its capacity is approximately 2500 mAh. Why is the parameter lower than in all smartphones? The fact is that a high current output is required here. Remember the batteries in electric scooters and quadrocopters - they are also large and not very high capacity.
The Xiaomi robot vacuum cleaner turned out to be more powerful than its competitors, so it consumes a full charge in just an hour and a half or even faster. From Redmond and Tefal you can expect continuous cleaning for two hours. Including floor cleaning. But this is not a significant advantage, unless you live in a huge private house, the area of \u200b\u200bwhich seems endless. Most often, two hours is more than enough for the vacuum cleaner to examine literally all corners. And let's not forget that all five devices can stand up on their own charging station - in which case they can then return to work.
As for Midea M7 and Roborock S5 Max, they are ready to work for three hours! That is why the choice in their favor is made even by the owners of large premises - warehouses, trading floors and everything in the same spirit. This battery life is due to the presence of a 5200 mAh battery inside. At the same time, in terms of charging time, they also outperform most competitors – this process lasts no more than three hours.

6. Equipment
Looking at the contents of the boxesAs expected, all five robotic vacuum cleaners are complemented by a soft bumper. Therefore, you do not have to worry about the safety of furniture and pets. And we haven't even mentioned the UV lamp built into the Redmond product! Now this is very important, because due to it, the room is disinfected, albeit not to the full extent. As for the equipment, in the box with the Tefal vacuum cleaner there will be a turbo brush - the best accessory for dealing with wool and hair. A large number of attachments are also in the box with Redmond - for example, two microfiber cloths, an electric brush and the remote control we have already mentioned are waiting for you. Everything is in order with this case and Xiaomi products.
The Midea M7 robot vacuum cleaner is interesting in that it comes with two side brushes - in this regard, it can be compared with the same Redmond and Tefal. Otherwise, its package is completely identical to the rest of the devices (except that some models from our comparison come with a remote control). The same can be said for Roborock. In a word, it is extremely difficult to give an impression to any particular device.

7. Price
Not all vacuum cleaners cost the same money.More recently, even for relatively simple robotic vacuum cleaners, they asked for a huge amount. And there is nothing to say about models with wet cleaning. But technology is constantly evolving, in connection with which the situation has changed radically.For Tefal and Redmond they ask for about 15 thousand rubles. For Xiaomi - a little more. Of course, this still cannot be called a budget purchase. But many of our readers still can afford such devices. And these robotic vacuum cleaners are not the “blind kittens” that used to be sold for that kind of money. They are equipped with many sensors, thanks to which they are perfectly oriented in space.
Name | average price |
Midea M7 | 16 500 rub. |
REDMOND RV-R650S | 15 300 rub. |
Roborock S5 Max | 33 500 rub. |
Tefal RG6871WH | 15 000 rub. |
Xiaomi Mi Robot Vacuum Mop | 16 500 rub. |
It should be noted that finding a Tefal product is becoming more and more difficult every day. It seems that the manufacturer was not satisfied with the sales, in connection with which he decided to leave this market. Or at least take a break. What can not be said about Roborock. Her robot vacuum cleaner is found on the shelves of online stores almost most often. But the price tag will not suit everyone. To be honest, it is completely incomprehensible why it turned out to be so overpriced. In this regard, even Midea M7 looks much more interesting, although its cost cannot be called the lowest. Is a laser rangefinder really that expensive to manufacture?
8. Comparison results
In favor of which vacuum cleaner should you choose?
It is extremely difficult to recommend any specific model for purchase. Perhaps the optimal price-quality ratio traditionally has a Xiaomi product. The Chinese are not asking for outrageous money. At the same time, in many respects, their robot vacuum cleaner is not inferior to even more expensive counterparts.In particular, he also has at his disposal a laser rangefinder, due to which a competent construction of a map of the room takes place.
