A frame body may be parallel to and proximate with an external surface of a structure and extend substantially horizontally from a first side to a second side. A connecting portion may be provided to be attached to a cable to provide for vertical movement of the frame body. A robotic arm may be affixed proximate to a bottom of the frame body and be able to move horizontally during treatment of the external surface. Moreover, the robotic arm may extend to an end proximate with the external surface, and a cleaning portion may be attached to the robotic arm near the end proximate with the external surface. The robotic arm may rotate, vertically moving the cleaning portion during treatment of the external surface. In addition, the cleaning portion may be separately rotated to remain substantially parallel to and proximate with the external surface during rotation of the robotic arm.

A surface washing drone with a modular cleaning head unit. The surface washing drone may also include a safety failover mechanism. The surface washing drone communicates and works together with other surface washing drones in a group.

A suction apparatus and a glass-wiping device with the suction apparatus. The glass-wiping device sucks onto the surface of a glass via the suction apparatus. The suction apparatus comprises a suction cup unit (1). The suction cup unit (1) comprises an inner suction cup (11) and an outer suction cup (12). The inner suction cup (11) is arranged on the inside of the outer suction cup (12), where a chamber on the inside of the inner suction cup (11) forms an inner negative pressure chamber (13) via vacuum suction, and where a chamber between the inner and outer suction cups (11 and 12) forms an outer negative pressure chamber (14) via vacuum suction. The glass-wiping device sucks onto the surface of the glass via the inner negative pressure chamber (13) and/or the outer negative pressure chamber (14). The glass-wiping device sucks onto the surface of the glass via the suction apparatus, is capable of ensuring sufficient vacuum pressure, and prevents the phenomenon of the glass-wiping device falling from the surface of the glass.

A drone for cleaning an outer wall of a high-rise building is configured to float and move in the air. The drone includes a drone main body and a floating transfer unit for floating and moving the drone main body in the art. The drone main body has a camera unit provided to photograph the exterior of a building and driving wheels on one surface thereof to be guide to the exterior of the building. The drone main body further has a buffer angle member to cushion an impact with the building and a washing nozzle unit which sprays water onto and washes the exterior of the building. Accordingly, by cleaning the exterior or a window of a skyscraper using the drone, there are the effects of reducing the costs of cleaning a skyscraper, simplifying a cleaning operation, preventing human accidents due to falls, and reducing cleaning time.

The present invention relates to a duster cloth for a cleaning robot and a cleaning robot using the duster cloth. The duster cloth comprises a detachable connection part (21) close to a base of the robot, a wiping cloth (22) close to a surface to be cleaned, and an elastic sealing layer located between the detachable connection part (21) and the wiping cloth (22).

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.
