Abstract: A wall cleaner hanging structure for hanging a wall cleaner includes a frame; at least a fastening unit for fastening the wall cleaner hanging structure in place; a liquid storage device for storing and conveying a liquid for washing a wall surface; a cable elevation device for controlling vertical movement of the wall cleaner; a tube and wire elevation device for controlling the length of a wire and a delivery tube; a plurality of guiding wheels for guiding the wire and the delivery tube to the wall cleaner; and a wall cleaner moving device for adjusting the distance between the wall cleaner and the wall surface. The wall cleaner hanging structure is freely moved and stored, works in conjunction with the wall cleaner to wash the wall surface in an automated manner, such that wall cleaning workers are less likely to get injured and fall victim to work accidents.

Abstract: A wall cleaner structure hung by a cable and adapted to wash a wall surface includes a frame; a cleaning device for washing the wall surface; a suction device for drawing in a liquid having been used in washing the wall surface; and a collection device for collecting the liquid. The wall cleaner structure washes the wall surface in an automated manner, prevents accidents, and prevents waste liquid from flowing downward across the wall surface or even falling to the ground.

Abstract: An outer wall cleaner for washing an outer wall of a building includes a frame; an upper water inlet and a lower water inlet which are disposed on a front side of the frame and adapted to face the outer wall of the building; a water-driving member disposed within the frame and adapted to communicate with the upper and lower water inlets; a scrubbing member disposed on the front side of the frame and positioned between the upper and lower water inlets; a water-spraying member disposed on the front side of the frame and positioned between the upper and lower water inlets; and a water-taking member disposed on the front side of the frame, adapted to come into contact with the outer wall of the building and take water, and positioned above the upper water inlet, wherein an opening is disposed on a water-taking-member-facing side of the upper water inlet.

Abstract: A building exterior wall cleaning apparatus includes a housing being provided on a top with a set of external hoisting hangers, at a front side with a spray unit, and at a rear side with at least one gas producer; at least one cleaning unit being rotatably mounted to a front side of the housing next to the spray unit; and a driving unit being mounted in the housing and connected to the at least one cleaning unit. The at least one cleaning unit may be tightly pressed against a building exterior wall by airflow produced by the gas producer and to clean the building exterior wall in one stroke of the cleaning unit, so as to enable safe, efficient, automated and unmanned building exterior wall cleaning operation.
