A suction-adhering vehicle for removing a coating from a surface includes a resilient suction ring (e.g., a tubular ring, an inner tube, or a solid foam ring) defining a substantially enclosed region between vehicle frame and the surface. Spray nozzles within the enclosed region direct fluid against the surface to remove the coating. An exhaust port leading from the enclosed region is connect to an external suction source that maintains reduced pressure within the enclosed region and withdraws fluid and coating debris from within the enclosed region. Caterpillar treads or other drive means move the vehicle along the surface. The suction ring is releasably secured to the vehicle frame by a frictional fit with engaging means extending from the frame, such as collar that engages the inside diameter or the outside diameter of the suction ring. This allows the suction ring to be quickly and easily replaced in the field. The orientation of the suction ring can also be reversed so that both sides of the ring are used as wear surfaces. The wear surfaces of the suction ring can be coated with polyurea, metal powder, or other wear-resistant materials to increase its useful life.
