Robot cleaner
A robot cleaner includes a body to travel on a floor; an obstacle sensing unit to sense an obstacle approaching the body; an auxiliary cleaning unit mounted to a bottom of the body, to be extendable and retractable; and a control unit to control extension or retraction of the auxiliary cleaning unit when the obstacle is sensed. The control unit prevents the auxiliary cleaning unit from extending if a signal is received from a charger.
