The round brush 21 includes round brush body 211 and the flexible layer 212 of the outer face of treating cleaning of the cover of round brush body 211, and flexible layer 212 can adsorb the water spot to realize the cleanness of water spot. In this embodiment, the flexible layer 212 is embodied as a fleece made of fluff with good water absorption for efficient wiping of the surface to be cleaned.

Because the rolling brush 21 and the supporting wheel 22 are supported on the surface to be cleaned in a matched mode, the pressure of the rolling brush 21 on the surface to be cleaned is large, the rolling brush 21 is seriously abraded when being cleaned, and when the rolling brush 21 finishes cleaning the surface to be cleaned and rolls backwards, the flexible layer 212 is extruded by the surface to be cleaned, water stains are easily extruded to the surface to be cleaned, and water stains are left.

In order to avoid the above situation, in this embodiment, the scrubbing brush mechanism further includes a balance assembly 300, one end of the balance assembly 300 is rotatably connected to the case 100, and the other end is a free end, the balance assembly 300 includes a balance 33, the balance 33 is disposed on the free end so that the balance 33 swings with the advance and/or retreat of the rolling brush 21; wherein, when the ground brush mechanism moves backwards, at least the balance wheel 33 and the supporting wheel 22 cooperate to support the ground brush mechanism, and when the ground brush mechanism moves forwards, at least the rolling brush 21 and the supporting wheel 22 cooperate to support the ground brush mechanism.

By adopting the structure, the balance 33 is not contacted with the swinging space 11 all the time in the swinging process of the balance assembly 300, and the rotation of the balance 33 is not limited. Preferably, the third limiting member 14 and the fourth limiting member 15 can be integrally formed for convenience of production and assembly, and in a preferred embodiment, the first limiting member, the second limiting member, the third limiting member and the fourth limiting member can be integrally formed for further improving the convenience of production.
