When the Xiaomi Robot Vacuum S20 is turned on for the first time, there is no map in the Mi Home/Xiaomi Home APP.
To let the Xiaomi Robot Vacuum S20 quickly build maps, please refer to the following steps:
1. Place the main unit on the Charging Dock;
2. Open the Mi Home/Xiaomi Home APP >> select [Device card] >> tap the three-dot icon at the upper corner >> [Create map] >> [Quick map creation] >> tap [OK].
The main unit will only build maps but not clean. After the main unit automatically returns to the Charging Dock, the map construction is completed and the map is automatically saved.
Note:
During the mapping process, please do not move the Xiaomi Robot Vacuum S20, and keep it away from children and pets.
