The robot takes perseverance and maneuverability. Its small size and low height enable it to penetrate into places where it was inconvenient or even impossible to reach before. For example, the robot easily cleans under a huge sofa. The front wheel spinning in all directions gives excellent maneuverability, the robot is able to turn around on the spot. Even inflated interior sills are within his power. At the same time, I still do not understand the manner of his cleaning. There is no clear route. Sometimes misses areas with dust for unknown reasons. It's good that it runs on a timer every day, so this does not really affect the overall result. And the result is that now you rarely see crumbs, a dusty streak or a ball of matted wool on the floor.
