ABSTRACT:
A system for treating a surface, such as the outside surfaces of a tall building which can be operated remotely without the need to place a worker in close proximity of the surface to be treated. The system includes a vertical supporting column onto which is mounted a treatment unit. The treatment unit can carry out washing, painting, sandblasting, and similar operations and includes mechanisms for allowing the working head of the unit to be angles with respect to, as well as to move parallel to and perpendicular to, the surface being treated. In another embodiment, a window cleaning unit is suspended from the roof and is allowed to descent while cleaning the exterior surfaces of the windows.
