Abstract: A heatable ceiling boom for washing facilities, which is rotatably mounted on a bearing shaft that is fastened to the ceiling or to a wall of a wash box, and which is made up of one or more support arms via which the washing medium is supplied from the bearing shaft to high-pressure hoses leading to the operating means in the form of a washing brush and/or spray lance, for example, wherein the high-pressure hoses have an electrically heatable design, and at least one rotational power distributor is situated on the bearing shaft for supplying electrical energy from the stationary bearing shaft to the support arms rotatably mounted thereon, wherein the electrical heating takes place via a heating cable that is led inside the high-pressure hose with sealing.

Abstract: A surface cleaner with a connection to a high-pressure medium, consisting of a pot- shaped housing (11) open on one side, in which at least one rotor arm (6) is rotatably mounted on a swivel joint (5) in the center of the housing, wherein one or more cleaning nozzles (27) are arranged on the rotor arm (6), which are connected in a fluid-conducting manner to the high-pressure medium guided through the swivel joint (5), wherein the housing (11) is designed to be able to turn 180 degrees for a second operating mode, wherein the surface cleaner can be operated in the at least two different operating modes, wherein the first operating mode consists of a surface cleaning operation with the housing (11) and the cleaning nozzles (27) arranged therein pointing downwards toward a floor, and wherein the second operating mode is designed as a cleaning operation in which the housing (11), turned over 180 degrees with the cleaning nozzles (27) pointing upwards, is directed toward a cleaning surface arranged at a distance f

Abstract: A surface cleaner with suction and simplified operation, which can be moved by hand using a push bar (30) over a cleaning surface on the floor, and consists of a pot-shaped housing (6) that is open towards a cleaning surface, in which housing at least one rotor arm (7) having spray nozzles (10) attached to it is driven to rotate under the action of a high-pressure medium, wherein a manually operated valve device (1, 3, 25, 26) is present, which supplies the high-pressure medium selectively to one or more rotor arms (7) and/or to the suction device (8), wherein, for two-handed operation, the manually operated valve device consists of two spatially separated operating handles (1, 3) with manually operated operating levers (25, 26), which are arranged at the two ends of the push bar (30) of the surface cleaner.

Abstract: A heatable ceiling boom for washing facilities, which is rotatably mounted on a bearing shaft (14) that is fastened to the ceiling or to a wall of a wash box, and which is made up of one or more support arms (2) via which the washing medium is supplied from the bearing shaft (14) to high-pressure hoses (30) leading to the operating means in the form of a washing brush and/or spray lance, for example, wherein the high-pressure hoses (30) have an electrically heatable design, and at least one rotational power distributor (25) is situated on the bearing shaft (14) for supplying electrical energy from the stationary bearing shaft (14) to the support arms (2) rotatably mounted thereon, wherein the electrical heating takes place via a heating cable (10) that is led inside the high-pressure hose (30) with sealing.
