There is nothing to compare with, the first robot in use. In general, it works well. The recognition function, by the way, is disabled in the settings if desired. This makes the neat monsieur an evil devourer of everything that is lying on the floor, but at the same time he breaks more aggressively into some places where it is worth stopping by and which he avoids with intellectual recognition. For example, starts to push the curtains. He has an obstacle avoidance radius of 20 centimeters, probably - he will not drive too close to the wire on the floor. Washing the floor is a nice bonus, the dirt from under the rug in the bathroom and a little dried dirt from the shoes washes. Caustic stains in the kitchen - no. But you have to rub them with your hands.
