ABSTRACT:
This invention relates to cleaning large format movie screens, such as vinyl screens and painted screens. There are different variations of the basic concept of using a cleaning head, cables, pulleys, an upper mounting bracket and a winch. In one instance a track may be used instead of a cable. The winch is connected to the cleaning head using cables and is used to move the cleaning head vertically across the screen through pulleys and other arrangements.
