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 returned to the dock 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 re-generate the map. If the charging dock is too far
away, it may not be able to return to recharge and must be placed on the charging dock manually.
