Abstract
An easily manufactured and inexpensive window cleaning device has identical upper and lower plates forming a head for receiving a sponge and a squeegee on opposite sides. The upper and lower plates have a horizontal section and opposite longitudinal edges. A radial clamping section of each plate is disposed at one longitudinal edge for clamping to the sponge. An L-shaped shoulder is disposed at the opposite edge, for engaging a complementarily shaped foundation spline of the squeegee, from which the blade of the squeegee protrudes. The two plates are of identical shape, being placed in mirror image position when attached together, for example using rivets that also attach a stem for receiving a handle. The sponge is secured within the radial sponge clamping section without the need of an internal stiffener, and the squeegee blade is oriented to an advantageous angle by the channel formed by the opposing L-shaped shoulders. The arrangement of the squeegee blade minimizes the extent of bending required to form the squeegee engaging section.
