cleaner shall be operated automatically (When the
robot vacuum cleaner is completely discharged,
you shall need to charge for a while for automatic
operation).

the charging dock and the charging contacts on the
robot vacuum cleaner.
3. Please ensure that the on/off button on the side of the

1. There are too many obstacles around the charging
dock. Please place the charging dock to an area free
of obstacles.

Bring the robot vacuum cleaner closer to the charging
dock and try again.
