Compared to another robot, which, though a little more expensive (there is something to compare with), is less "smart" and convenient, although in general there are basic functions. It passes first as a snake, then goes to the uncleaned zones that are only known to it (the map is not built in the application in the process), then along the perimeter. Unpredictable, because the card is not visible during the cleaning process. If you want to manage cleaning by zones, by rooms, see where your vacuum cleaner is at the moment (cleaning map), then this is not the right vacuum cleaner. However, he copes with his task and works out his price.
