The floor brush mechanism 1000 facilitates ensuring that the cleaning elements 230 are substantially in line with the floor surface, improving the cleaning ability of the floor brush mechanism 1000. Further, the outer circumferential diameter of the elastic member 220 is smaller than that of the cleaning member 230, so that the elastic member 220 prevents the cleaning member 230 from blocking the wall panel or corner.

More specifically, the diameters of the cleaning member 230, the elastic member 220, and the turntable 240 are reduced one by one to avoid interference with each other. Specifically, the diameter of the turntable 240 is smaller than that of the elastic member 220, so that the elastic effect of the elastic member 220 can be sufficiently ensured, and the deformation of the elastic member 220 can be ensured. The cleaning elements 230 are larger in diameter than the resilient elements 220 to help ensure that the cleaning elements 230 are raised and thus ensure the outward appearance of the floor brush mechanism 1000.

To avoid this problem, the mount 100 includes a body 110 and a stopper 120. The dust suction opening 111 is opened on the body 110, the blocking part 120 is arranged at the rear of the wiper strip 210, and the blocking part 120 covers the dust suction opening 111 and keeps a preset distance from the dust suction opening 111, so that the rear and the lower part of the dust suction opening 111 are blocked, the direction of the wiper strip 210 is left open, and garbage can enter the dust suction opening 111. Specifically, the blocking portion 120 has three blocking walls disposed on the body 110, the three blocking walls respectively block the rear and the left and right sides of the dust suction opening 111, the blocking portion 120 further includes a blocking wall simultaneously connected with the three blocking walls, the blocking wall is disposed at one end of the three blocking walls far away from the body 110, and the blocking portion 120 is parallel to the surface of the body 110, the structure encloses the periphery of the dust suction opening 111, which is beneficial to improving the recovery rate of the garbage.
