Abstract: This disclosure relates to systems, methods and apparatuses for removing precipitation from an exterior of a building in an expedited and automated fashion. The precipitation removal system includes one or more sweeper assemblies and one or more hoisting assemblies. The sweeper assemblies are suspended from the roof, ledge or other portion of a building. The hoisting assemblies assist the sweeper assemblies with vertically traversing the exterior of the building. As a sweeper assembly vertically traverses the side of the building, precipitation that accumulates on the exterior of the building is removed. The sweeper assemblies can remove precipitation from connecting structures on the exterior of the building which are used by building maintenance personnel to perform maintenance operations on the exterior of the building.
