Abstract
The elastic sealing layer is attached to both the detachable connection part (21) and the wiping cloth (22). The elastic sealing layer is made from a foamed EPDM material (23), an integral skin sponge (33) or a common sponge (43), wherein a sealing film (24) is arranged on at least one side of the common sponge (43). The detachable connection part (21) may be a Velcro. With the structure of the elastic sealing layer between the detachable connection part and the wiping cloth, the duster cloth has good elasticity, and the air-tightness of the negative pressure chamber of the cleaning robot is greatly improved.
