I bought it in August, at the beginning of October it began to constantly give out the error “side brush error, something may have been wound”, although there was nothing on the brush. Under it, too, as well as inside the twisting mechanism. Restarting and resetting the factory settings did not help - 5 minutes after the start of cleaning, it gives an error. Probably the problem is in the "head" of the robot, which upsets .
