How does the Xiaomi Robot Vacuum S20+ sweep the whole house?

The ways of the Xiaomi Robot Vacuum S20+ sweeping the whole house are listed below:
1. Cleaning method without a map: For the first cleaning without a map, the robot vacuum will first follow the edge of the 4.5 × 4.5m area, and then use a bow-shaped cleaning until all areas are covered;
2. Cleaning method with a map: After starting, the robot vacuum will clean by room, first cleaning along the edge, then cleaning in a bow shape, and complete the cleaning of the room in sequence. In the Vacuuming & mopping mode, the cleaning order of the room is different from the Vacuuming mode to avoid secondary pollution caused by the robot vacuum passing through the cleaned room.
Note:
1. All motors on the robot vacuum have an overload protection function, including the main brush motor, side brush motor, drive wheel motor, and mop motor. When foreign objects enter or the blockage causes an overload, the protection will automatically start to prevent the motor from being damaged;
2. If you want to edit the room on the Xiaomi Robot Vacuum, go to the [Mi Home/Xiaomi Home] APP >> select [Xiaomi Robot Vacuum S20+] >> [Area editor], you can divide the room, merge rooms and rename the rooms here.
