Squeegee is a window cleaning tool that is basically a rubber blade on the handle. As the squeegee traverses the window surface, a rubber blade is pressed onto the glass, removing practically all water/liquids from the glass surfaces, leaving the surface clean and shiny, without marks and streaks. The problem is the removal of that water from the rubber blade itself. Some squeegees also feature a sponge/microfiber pad to help remove excess water, but they have to be squeezed periodically. http://www.imass-home.com/home-care/window-vacuum-cleaner/
