Robot cleaner and control method for the same

摘要

A robot cleaner (1) includes a body (10) to travel on a floor, an obstacle sensing unit (61,62) to sense an obstacle approaching the body (10), an auxiliary cleaning unit (21,22) mounted to a bottom of the body (10), to be extendable and retractable, and a control unit to control extension or retraction of the auxiliary cleaning unit (21,22) when the obstacle is sensed. The control unit recognizes a zone of a charger and performs a control operation to prevent the auxiliary cleaning unit (21,22) from extending in the charger zone.
