Optionally, the turntable 221 is oblong and the turntable 221 has two opposite linear sides, and the mop fits into the turntable 221. In addition, the long axis directions of the two rotating disks 221 are perpendicular to each other, so that the two rotating disks 221 can alternately clean the area between the two rotating disks, increasing the cleaning area of the rotating disks 221.

In addition, the cleaning device 20 is disposed at the bottom of the cleaner floor brush so that the cleaning assembly 22 with the mop cloth of the cleaning device 20 can be brought into contact with a surface to be cleaned, thereby performing a cleaning function when the cleaner floor brush is dragged. And because the cleaning device 20 and the dust collection assembly 30 are both installed in the dust collector floor brush, in order to reasonably distribute the assembly space in the dust collector floor brush, the whole structure is more compact, and meanwhile, in order to ensure the appearance of the dust collector floor brush to be simple and beautiful, the shape of the dust collection assembly 30 needs to be adapted to the appearance contour of the cleaning device.
