Great helper for maintenance cleaning. Pros below: Not noisy in standard mode. Decent cleaning quality. Good at building a room map. Charging is enough to clean an area of 75-80 m. An excellent product for such a price. Easy to clean. Everything is well removed and installed. Has cons: It is difficult to see the mirrored or shiny legs of chairs. The moistening of the cloth is not uniform. With Alice smart home, there is no way to set cleaning in a separate room - only the whole apartment.
