The seal 150 may have some elasticity that maintains the seal between the suction cup assembly 100 and the surface to be cleaned. For example, in some embodiments, the sealing member 150 may be a foam sponge having elasticity and air impermeability, and the outer layer of the sealing member 150 wraps at least one cloth or is coated with a smooth flexible coating. Therefore, on one hand, the sucker component 100 can keep low friction force in the sliding process of the surface to be cleaned, the sucker component 100 is convenient to slide, and on the other hand, the sucker component 100 can keep good air tightness in the sliding process.

When the suction cup assembly 100 is adsorbed on the surface to be cleaned, the chassis 300, the elastic block 140 and the sealing member 150 form a suction cup inner cavity, the surface to be cleaned and the suction cup inner cavity form a closed cavity, and the gas valve 200 can extract gas in the suction cup inner cavity to form negative pressure in the suction cup inner cavity, so that the cleaning robot can be adsorbed on the surface to be cleaned. When negative pressure is formed in the suction cup cavity, the elastic block 140 is compressed, the distance between the fixed member 110 and the movable member 120 is shortened, and the sealing member 150 is tightly attached to the surface to be cleaned.

Referring to fig. 6, according to some embodiments of the present invention, the elastic block 140 is a foamed member. The elastic block 140 is made of a foam material having elasticity and air impermeability, such as a foam sponge. The resilient block 140 acts as a seal, and the resilient block 140 also functions to compress and rebound to help restore the relative positions of the stationary member 110 and the moveable member 120 during sliding movement of the chuck assembly 100.
