Due to its absence, the noise level is reduced. It lasts an hour less on a single charge than Xiaomi Viomi Cleaning robot V-RVCLM21B. The suction power is lower than that of Okami S90. But the vacuum cleaner has a well-thought-out navigation system, pedantically passes the room and does not return to the already cleaned areas.

The presence of a laser lidar, the ability to control through the application, adaptation to the "Smart Home" distinguishes it from other TOP equipment. Noisier than the Okami S90, which is considered a major drawback. But you can set up a cleaning schedule for a time when the owners are not at home. It is also considered an inconvenience that the robot cannot carry out wet and dry cleaning at the same time.
