In general, if not the terms of the guarantee (spin as you like if it breaks), then a good vacuum cleaner cleans with dignity, and when it broke, it became very noticeable that it was not there. Thecomllision warning sensors on the front panel "died" after two months - that is at first he drove up to an obstacle and then, without hitting it, turned around and drove in a different direction, and then he seemed to be blind and began to poke at all objects and only then turn around, and recently hecompletely went crazy and now only when turned on it rotates jerkily and gives an error.. Such is the sadness. You can watch the video with the error here My full review of this robot vacuum cleaner model is at this link
