The mop assembly 800 is generally installed at one side of the rolling brush assembly 300, when the mop assembly 800 is installed, the structure for driving the mop assembly 800 to move generally occupies the space between the bottom wall of the housing 100 and the dust collection box 200, so that a gap 130 is formed between the bottom wall of the housing 100 and the dust collection box 200, the driving assembly 400 is installed in the gap 130, the space in the gap 130 is reasonably utilized, the space utilization rate inside the cleaning device is improved, the installation layout difficulty inside the cleaning device can be reduced by reasonably utilizing the space inside the cleaning device, more parts are installed under the condition that the volume of the cleaning device is basically unchanged, and the function of the cleaning device is improved.

In one possible application, the mop assembly 800 may be lifted by a ball screw arrangement or by a gear and rack arrangement.

In one possible embodiment, the housing 100 includes the bottom case 110 and the middle frame 120, and the roller brush assembly 300 is positioned above the bottom case 110 and below the dust collection box 200 and the middle frame 120, so that a space on the front side of the roller brush assembly 300 is omitted.

The middle frame 120 is a design reference for mounting the whole machine, the rolling brush assembly 300 comprises a rolling brush 320 and a bracket 330, the bracket 330 is fixedly mounted above the middle frame 120, the rolling brush 320 is mounted on the bracket 330, and the rolling brush 320 can rotate relative to the bracket 330. The bottom case 110 is installed under the middle frame 120, and serves as a fixing and decorating function. The motor 421 is fixedly installed below the middle frame 120, and can drive the screw rod 422 to rotate, the sliding block 412 is matched with the screw rod 422, the sliding block 412 moves left and right along the screw rod 422, one end of the sliding block 412 comprises a slope, namely a second inclined surface 411, which is used for being matched with the first inclined surface 310 on the bracket 330, the other end of the sliding block 412 comprises a contact, namely a touch control part 500, and the rolling brush 320 can be triggered to descend to a position detection switch (a second detection switch 700) and the rolling brush 320 can be triggered to ascend to a position detection switch (a first detection switch 600).
