Abstract
An automated building washing device generally includes a spray bar assembly coupled to a window washing swing stage. The spray bar assembly is horizontally movable from end-to-end along the longitudinal direction of a window washing swing stage while spray heads rotate so that a relatively large portion of building surface can be quickly cleaned. The spray bar assembly includes a hollow rotating bar and spray heads inside of a shroud so that the bar can rotate as water or cleaning solution is sprayed onto the building surface for cleaning.
