In one embodiment, the cleaning apparatus further comprises a floor mopping module comprising the wet cleaning head 120 and a liquid supply module comprising a liquid supply assembly that feeds cleaning liquid into the wet cleaning head 120. The wet cleaning head 120 may be disposed below the liquid supply assembly, and the cleaning liquid in the liquid supply assembly is transferred to the wet cleaning head 120 through the water supply mechanism, so that the wet cleaning head 120 performs wet cleaning on the surface to be cleaned.
