Problem Solution
Cleaning does not resume after recharging
Make sure that the robot is not in DND mode. DND mode will prevent cleanup. When cleaning a
space requiring a top-up charge, if the robot was placed manually on the Charging Dock before it
is recharged automatically, it will not be able to continue cleanup.
The robot cannot return to the charging dock
after spot cleaning or when it has been moved
manually.
After spot cleaning or a significant position change, the robot will regenerate the map. If the
charging dock is too far away, it may not be able to return for recharging and must be placed
on the charger manually.
