Definitely one of the best purchases I have made. I use a year. The robot vacuum cleans very well. The vacuum cleaner itself draws maps and bypasses barriers very cool. There are downsides, but not significant ones. If the bedside table is low, then it can get stuck under it, or it can wrap small things on the floor that are on the floor, but it immediately stops and says that it is necessary to clean the brush. We often turn it on when I'm not at home. Very comfortable came home, and the rooms are already clean.
