The dust collection device adopts the equidirectional rotating cleaning cloth coaxial and uniform water spraying control, so that the cleaning cloth is uniformly wetted and easily dried, and no water mark is left after being dragged. The dust suction device solves the problem that the dust suction device cannot wet and mop in the related technology, can replace appliances such as a floor washing machine and an electric mop, integrates multiple functions, and realizes that wet garbage is left in the sewage tank body 101 and dry garbage is left in the dust collecting cup of the dust collector. The dust collection device has a dry-wet wind separation function, and solves the problem that dry-wet mixed garbage is difficult to clean in the related technology.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, should not be construed as limiting the present invention.
