Virtual no-go zone and barrier
The Mi Home app can be used to draw virtual no-go zones and barriers
to keep the robot from entering the areas you define.
Note:
"Map Saving Mode" must be turned on in the Mi Home app to use virtual no-go zones.
Virtual no-go zones and barriers should only be used to customize the cleaning area. It
should not be used to isolate hazards.
Moving the robot manually or making significant changes to the home environment may
cause the loss of virtual no-go zones and barriers
