Abstract: A window cleaning device adapted to clean facing surfaces of closely spaced parallel windows is made of an elongated head member having scrubber material associated therewith, and a rigid elongated straight handle which joins the head member in T-configuration. The head member has a central portion terminating in flexing regions, and rigid outer portions emergent from the flexing regions. When the head member is inserted between the windows, and the handle is twisted about its axis, the rigid outer portions are deflected in opposite directions away from the handle and thereby contact both facing window surfaces.
