Referring to fig. 1, a cleaning apparatus 100 of the present application is used for cleaning a surface to be cleaned, which may be a floor surface, a wall surface, or a dirty surface of another object, and the application target or the application scene of the cleaning apparatus 100 is not specifically limited in the present application.

The cleaning device 100 of the present application has both the suction function and the floor mopping function, which can be activated simultaneously, or operated step by step or independently according to actual requirements. Wherein, the suction function can be a dust absorption function or a water absorption function.

Taking the handheld floor washing machine 100 as an example, the handheld floor washing machine 100 comprises a rod body, a cleaning head 2 arranged near the bottom end of the rod body, a liquid storage assembly 3 for providing cleaning liquid to the cleaning head 2 and collecting the used cleaning liquid, and a dust suction assembly 4 for generating negative pressure. When the hand-held floor washing machine 100 is started, the cleaning solution in the reservoir assembly 3 flows to the cleaning head 2 so that the cleaning head 2 can wet and then clean the surface to be cleaned. And the negative pressure that dust absorption component 4 produced makes most dirty liquid and particulate matter enter into stock solution component 3 and store to improve the clean efficiency of hand-held type floor scrubber. The cleaning head 2 comprises at least a housing 21, a cleaning attachment 22 rotatably connected to the housing 21, and a driving member for driving the cleaning attachment 22 to rotate, wherein the driving member drives the cleaning attachment 22 to rotate so as to separate the dirt from the surface to be cleaned. In this embodiment, the cleaning attachment 22 is a roll brush and the driving member is a driving motor 41.
