Xiaomi Roborock S5 Max

best robot vacuum cleaner -Xiaomi Roborock S5 Max

This device is the best buy robot vacuum cleaner in 2020. Designed for all types of cleaning of any hard floor coverings, as well as the low-pile and medium-pile carpets. A powerful motor with a suction force of 2000 PA and a turbo brush does not leave a trace of dust that falls into the capacious dust collector (460 ml). The trash can is equipped with a HEPA filter that can be easily washed.

The robot navigates in space using LDS and SLAM technology which builds a high-precision scheme of the room. The memory function helps the device to memorize up to 3 room schemes, which makes Xiaomi Roborock S5 Max a great device for working in multi-level houses. The vacuum cleaner is perfect for cleaning large apartments, a capacious lithium-ion battery of 5200 mAh is designed to supply the device with a charge for 150 minutes of operation. In comparison with other models, Roborock has a feature called a no-mop zone, it is quite a useful function, the vacuum cleaner ignores all carpet coverings, leaving them dry. There is also a smartphone app that includes the following modes and options: virtual restriction, carpet protection, the schedule of cleaning, and others.

Roborock S6 also deserves the title of the best model. It has similar characteristics, but the container for liquid is slightly smaller and there is no option no-mop zone, but you can be creative and place virtual walls in the app where it is necessary.


iRobot Roomba i7

top robot vacuum - iRobot Roomba i7

Unlike Xiaomi, Okami, and 360 models, this vacuum cleaner from the American company iRobot is designed exclusively for dry cleaning. A special feature of the device is its working unit with two rollers-extractors that clean various floor coverings and do not wind the hair around. The quality of cleaning is provided by an adjustable suction force, depending on the type of flooring and the degree of contamination. iAdapt 3.0 navigation based on an overview video camera is responsible for the spatial orientation of Roomba i7. You can download a mobile app to work with the scheme of your house and configure cleaning parameters. Up to 3 schemes are stored in its memory, as in Roborock S5 Max and 360 S7 robots.

The i7+ version differs from the standard i7. The i7+ has a base station with automatic cleaning of the dust collector. When the robot arrives for charging, the station pulls garbage from the dust collector into its large 12-liter container.

The robot is not at the top of the list because the cost is high, and the new Roomba s9+ is even more expensive. It is too expensive even for a smart vacuum cleaner that performs dry cleaning perfectly.


360 S7

best buy robot vacuum - 360 S7

360 S7 model from a Chinese producer has similar functions, characteristics, and design as Xiaomi. The vacuum cleaner has a washer at the top, one end brush, the same principle of dry cleaning, and the suction force (2000 PA). Only the battery is smaller — just 3200 mAh, this characteristic makes the vacuum cleaner similar to Okami u100. The smart assistant even repeats the carpet protection function, which ignores them and keeps dry. Wet wiping of the floor is also simplified – a pallet with a 150 ml container is supplied for direct wetting of the cleaning cloth. There is a mobile app to control the device, you can view saved schemes of rooms (remembers up to 10 schemes), you can send the vacuum cleaner to any of the cleaning rooms, set virtual borders, and much more.

Its main feature is memory function and carpet protection.


Ecovacs Deebot ozmo 950

robot vacuum review - Ecovacs Deebot ozmo 950

Ecovacs Deebot ozmo 950 is a floor vacuum robot that can perform wet and dry cleaning simultaneously. The low height of the robot allows the device to clean under low furniture. Navigation is based on Smart Navi 3.0 technology and includes a laser range finder and IR sensors. Dry cleaning is performed with two side brushes and a turbo brush. The main brush is more convenient comparing to Deebot ozmo 930, and it can change positions, thus increasing the quality of cleaning on carpets due to the shock absorption of the brush. Its motor power is 1500 PA, it makes this robot inferior to the vacuum cleaners in the list, but the suction force is quite enough for cleaning carpets with low and medium pile. Moreover, the robot overcomes high obstacles. Ecovacs Deebot ozmo 950 collects garbage in 430 ml container. Wet cleaning is performed using OZMO technology.

After filling the container tank with 240 ml, you can use the option of washing the floors. The intensity of wet wiping is regulated by an electronically controlled water pump. Water is distributed evenly over the microfiber due to special sensors. You can increase or decrease the water level depending on the degree of contamination or the type of floor covering via a mobile app. The functionality of the smartphone app is also expanded, you can also set virtual borders, view a scheme of the room, select rooms for cleaning, program a schedule, and so on.


Budget models

There are simplified requirements for vacuum cleaners in the middle price category. It is not obvious that budget robots are not very different from premium devices, but they are inferior to expensive vacuum cleaners. The smart vacuum cleaner must have a motor from 1000 to 1500 PA, perform both dry and wet cleaning of the floor, including a separate container or a module. A smartphone app is used to control the robot, models with remote control are becoming less popular nowadays. There are no doubts that the device should build a scheme of the room and navigate not only by IR sensors.
