The present invention relates to a cleaning robot. At least a first cleaning roller brush and a second cleaning roller brush are provided to beat and sweep debris on a surface to be cleaned. That is, beat sweeping is performed on the surface to be cleaned at least twice, thereby effectively preventing omission of debris. Moreover, a high-power fan is used in conjunction to quickly and effectively suction the debris beaten and swept by the cleaning roller brushes into a dust box, thereby greatly improving the cleaning efficiency of the cleaning robot, and obtaining a better cleaning effect.
