Abstract
An automated exterior building cleaning system particularly well suited for cleaning the window exteriors on a high rise building. By way of example the system is deployed on a rooftop rail system traversed by a movable platform from which a washing head is deployed over the edges of the building and lowered on cables for cleaning the window surfaces and other building elements. The system is configured for remote monitoring and control and provides a number of novel elements and safety features.
