摘要

The window cleaning nozzle is operated with a wet vacuum cleaner. An additional small water pump is present in the wet vacuum cleaner, which produces the splash-water in the cleaner. The water reaches to the roller brush and is sucked off by the longitudinal nozzle at the rubber lip. That intake flow is used at the same time as drive for the roller brush.
