After half a month of use, everything is fine! The cleaning effect of this robot is fine! It is not possible to use the manual mode directly at first because it first starts the edge cleaning mode itself and cannot use the manual mode from the application until it has completely scanned the room. I vacuumed normally, it can absorb dust, but has stronger suction. I touched the ground and there was almost no dust. Its application can control the water discharge from the water tank, and the third gear has the largest water discharge. With him I wouldn't have to sweep the floor myself. I recommend it!
