Robot cleaner and operating method thereof

摘要

A robot cleaner comprises a suction unit installed within a cleaner body, for sucking dirt on a floor; a driving unit for moving the cleaner body; a detecting unit mounted at the cleaner body, for detecting a height between a bottom of the cleaner body and a floor; and a control unit controlling the suction unit in response to signal from the detecting unit, for adjusting a suction force of the suction unit. Accordingly, cleaning efficiency of the robot cleaner can be improved by controlling the suction force for sucking dirt in accordance with unevenness of the floor.
