Abstract: The present invention provides a cleaning apparatus head for cleaning surfaces such as windows, solar panels, floors, walls Etc. The cleaning head facilitates rapid and uninterrupted cleaning work on the subject surfaces. The cleaning process incorporates scraping dirt by applying a wet sponge, as well as the disposal of grime by means of suction pump. The cleaning apparatus comprised of: a carrier for moving the cleaning head along the surface, a main body for holding the cleaning head parts, at least two wipers, movable forwards and backwards towards the surface, a sponge element located at the front of the main body, in between the two wipers, at least two movable arms for pushing and pulling the wipers by pistons and an electronic controller programmed for controlling the pistons movement, according to the cleaning head's movement direction.

Abstract: The present invention discloses a cleaning head apparatus operated by a carrier unit for cleaning a target surface. The cleaning head apparatus is comprised of: at least two loop straps attached next to each other by a main structured, each strap stretched and rolled on two axles operated by an engine, wherein at each cleaning session each strap has one part in dry state and one part of the in wet state, drying mechanism and wetting mechanism. The rolling of the straps is controlled, such that straps are not rolled during the movement of the cleaning head apparatus across the surface and are rolled, when the cleaning head apparatus reaches the edge of the target surface. During the cleaning movement, the wet strap is ahead of the dry strap and the straps are in constant contact with the surface.

Abstract: A system for cleaning windows in tall buildings, comprises a chassis (7) with means for its mounting on a suspended platform. (3) It also includes a rotating conveyor belt (61) mounted on the chassis and brushes (62) mounted on the conveyor belt. Each brush is mounted through extender means (63). Preferably, the conveyor belt includes means for its rotation in a generally horizontal direction. The means for rotating the conveyor belt include a first roller (71) and a second roller (72) mounted on the chassis. The conveyor belt is preferably mounted between the rollers and further includes motor means for rotating one of the rollers.

Abstract: A system for applying working equipment onto an external wall of a structure. One system comprises a suspended platform anchored to the structure, operably vertically moveable at a constant speed along the external wall; and a positioning system arranged to determine and control a predefined motion pattern of the working equipment relative to the suspended platform, the positioning system mounted on the suspended platform. The predefined motion pattern is selected such as to allow continuous and uniform application of the working equipment horizontally and vertically onto the external wall during the vertical movement of the suspended platform along the external wall. The predefined motion pattern comprises a diagonal movement comprising a vertical component and a horizontal component, wherein the vertical component is equal and opposed to the vertical movement of the suspended platform.

Abstract: A stabilized suspended platform comprises a platform suspended from a support unit by a cable. The support unit includes traction means for releasing or pulling part of the cable so as to set the platform at a desired height, and the platform includes propellers for fine movements or stabilizing the platform in space, further including remote control system with means for communicating with the support unit and the platform for controlling the spatial location of the platform. The support means may further include means for moving the platform laterally.
