Abstract
Disclosed is a cleaning robot having an improved driving and cleaning ability. The cleaning robot includes a dust collecting blade. A lower end of the dust collecting blade is bent in a direction opposite to the driving direction of the cleaning robot during operation of the cleaning robot, so that wobbling is not generated even though the ground surface on which the cleaning robot operates has bumps and gaps.
