WINDOW-CLEANING INSTALLATION

摘要

A window-cleaning installation comprises at least one cleaning device which preferably executes a back and forth movement on a window pane (12), in particular a windscreen wiper (13), guided at both ends. This window-cleaning device is therefore particularly suited for cleaning large areas without the risk that one of its ends will be lifted, for example by wind pressure. In a preferred embodiment, the window-cleaning device is driven by two counterdriven perforated belts (71a, 71b).
