An apparatus for cleaning a window comprising a wiper (10) and a belt and cog mechanism (16, 17) to move the wiper (10) across the surface of the window. A hose (30) extends through the window frame (4) and provides a means to convey water/detergent from the inside of the window onto its outer face. The wiper (10) may be activated without a motor by pulling, for example, a horizontal bar across its inner face and by means of the belt and cog mechanism (16, 17), the wiper (10) is moved over and wipes the window's outer face.
