Abstract
A robot cleaner includes a main body traveling along a floor surface and removing foreign substances in a cleaning travel mode, a sensor unit sensing obstacles around the main body, brush units sweeping foreign substances on a floor surface through rotation, and a controller reducing the traveling velocity of the main body and causing the main body to approach a front obstacle, if an area where a plurality of obstacles contacts each other is sensed by the sensor unit.
