The present disclosure relates to a robot cleaner, and more particularly, to a robot cleaner that replaces a battery charged in a charging base and a discharged battery of the cleaning robot simply by using power of a cleaning robot of the robot cleaner. According to the present disclosure, the cleaning robot of the robot cleaner may include at least two driving wheels, and the charging base may include a replacement unit mechanically connected to one of the driving wheel to replace batteries and a docking unit mechanically connected to the other of the driving wheel to dock the cleaning robot. Therefore, as the cleaning robot and the charging base are mechanically connected, there is an effect of exchanging batteries only by using a control unit and the driving motor of the cleaning robot.
