In general, a very worthy robot. With the exception of rare difficulties with a turn in the corners, I did not find any special problems. Got pros: Suction power, simple operation, the ability to start the robot for cleaning from anywhere with the Internet, the ability to create multiple maps Cons below: Sometimes it gets stuck (it tries to turn around for a long time and knocks on the walls), and not in narrow places (which would be logical), but simply in a corner where there is plenty of room for an unhindered exit. There is no way to get images from the camera (to be able to analyze what prevented the passage). The block for wet cleaning pours water unevenly, different amounts of water are used to clean the same area (I tried to check the valve, I did not find any problems, it may become clogged (stick together) over time).
