How to create multiple maps on the Xiaomi Robot Vacuum X20 Max?

For your reference, there are two methods to create multiple maps:
Method 1
Move the robot vacuum and omni station to the new environment, plug in the omni station, and connect the robot vacuum to it.
Open the [Mi Home/Xiaomi Home] APP >> choose [Xiaomi Robot Vacuum X20 Max] >> tap the three dots icon at the upper right corner >> select [Map list] to create a map. It is recommended to use the Quick map creation feature to create the second or third map.
After successfully saving a map, if you need to clean a specific floor, move the robot vacuum to the starting point near where the map was initially created, then manually select the corresponding map and start cleaning.
Method 2
If you prefer not to move the omni station to the new environment, you can only move the robot vacuum.
Open the Mi Home/Xiaomi Home APP >> choose [Xiaomi Robot Vacuum X20 Max] >> tap the three dots icon at the upper right corner >> select [Map list] to create a map.
Once the map is created, if you need to clean a specific floor, move the robot vacuum to that floor, manually select the corresponding map and disable the [Auto cleaning the mop] switch in the station settings. With this option disabled, the robot vacuum will begin vacuuming/vacuuming & mopping/mopping without returning to the omni station to wash the mop or empty the dust compartment. If wet mopping is needed, it is recommended to dampen the mop manually.
