The washing apparatus includes a platform that includes an operator station. The platform is adapted to move along the upright surface during cleaning. The platform is positionable along the upright surface along a length of the platform. The washing apparatus includes a powered cleaning structure that has cleaning elements that are adapted to contact the upright surface during cleaning. The powered cleaning structure is supported by the platform along at least a portion of the length of the platform. The washing apparatus includes a hoist system constructed and arranged to move the platform along the upright surface of the structure with lift cables.

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.

An apparatus for supporting an object at a window of a building comprises a first member, a second member, and a third member. The first member extends along at least a partial width of the window and abuts an interior surface of the building. The first member is configured to support the object by exerting an outward force on the interior surface of the building in response to a downward force exerted by the object. The first member also comprises at least two sections extending from the interior of the building to the exterior of the building. These sections may extend from the interior of the building to the exterior of the building about respective distal ends of the first member. The sum of the forces applied on the surfaces of the building are sufficient to secure the object to the building.

A building cleaning apparatus includes a platform adapted to be suspended along a side of a building. The platform includes a base and a barrier mounted on the base that encloses an operator work station. The building cleaning apparatus includes a building cleaning structure mounted beneath the base of the platform. The building cleaning structure includes a cleaning component that is driven by a motor. The cleaning component is mounted such that at least a portion of the cleaning component is directly beneath the base of the platform during cleaning of the building.

A cleaning brush apparatus that is mountable onto a platform that is suitably suspended from a building for cleaning exterior and/or interior surfaces of the building. The cleaning brush apparatus includes a cleaning brush that is rotatable relative to the platform about a rotation axis that is parallel to the longitudinal axis of the platform. The cleaning brush apparatus is mounted to the platform in a manner to define a walkway on the platform to the rear of the rotation axis that permits a human operator to walk on the platform behind the rotation axis and along at least a length of the cleaning brush apparatus. The cleaning brush apparatus may also be adjustably mounted on the platform to permit the cleaning brush apparatus to be adjusted in position on and relative to the platform in a direction parallel to the longitudinal axis.

A system for securing an air conditioning unit to a building without the need for any alteration and/or damage to the building itself. The system includes a cross bar, an air conditioning unit support, and a strut. The arrangement of the components results in the cross bar applying an outward force to an interior surface of the building and strut applying an inward force to an exterior surface of the building in response to the downward force exerted on the air conditioning unit support. The sum of the forces applied on the surfaces of the building is sufficient to secure the air conditioning unit to the building.
