Great vacuum cleaner. Smart. Draws a map, later you can select rooms separately (Through the Mi Home application). You can mark zones in which it will not work either with a square on the map or just with a line. Several power modes. Could not connect for a long time. I changed the region to China and the connection was immediately found. Speaks Chinese. There are many videos on how to do it in 2022, but I'm broke)) there is no need for this. Apartment 60 squares. Charge and half does not consume. Even when everything cleanly finds and collects dirt) It climbs normally through the rapids, even climbs onto a carpet 1 cm high without problems. The base is looking for itself.
