ABSTRACT:
A vacuum wall walking apparatus includes an annular body frame, a plurality of leg mechanisms extending downward from the body frame, and a plurality of suction cups attached to fore ends of the respective legs. The body frame is composed of a flexible member. The body frame thus constructed is bendable to conform to the profile of a curved surface when the vacuum wall walking apparatus is used with a wall having such curved surface. With this bending or deformation of the body frame, the suction cups are always able to retain an optimum posture to insure that the vacuum wall walking apparatus is stably held on the curved surface of the wall by a vacuum formed in the suction cups. The vacuum wall walking apparatus may include a surface treatment mechanism, in which instance a winch is provided to minimize or substantially eliminate the load exerted from the surface treatment mechanism to the vacuum wall walking apparatus. The surface treatment mechanism further includes a dust exhausting arrangement to secure a surface treatment operation without contamination of the surrounding environment.
