ABSTRACT:
A washing system for an elevated surface has a) a housing having a liquid application cleaning system therein; b) a support element that supports and elevates the washing system; c) a rigid member extending from a surface of the housing that faces away from a surface to be cleaned so that the cable, when supporting the cleaning system against the surface to be cleaned and connected to the housing at a connection point, exerts a rotational force on the cleaning system in relation to the fixed fulcrum at the roof top; and d) weights provided at a distance and direction from the connection point fulcrum to at least in part counterbalance the rotational force.
