We bought a robot to replace the old xiaomi mi, which cost 20 thousand and cleaned the apartment for 3 years without a single hitch. Cases when he got stuck and could not get out himself can be counted on the fingers. This new roborok in the first hour of trying got stuck 10 times in the simplest places, for example, between the two legs of a chair (!), and could not complete the cleaning of the entire area. The apartment is the same, the same places where the old one did it once or twice! This one sticks into corners, gets into a narrow place and gets stuck there, and continues to fidget and poke sideways endlessly, where the old one had long turned on the reverse gear and drove out. All the newfangled features, quiet motor and cameras are completely crossed out by the inability to cope with cleaning. The result is a complete fiasco, a return to the store.
