The Ettore Professional Backflip is a revolutionary breakthrough in window cleaning. It combines the two primary tools used by professional window cleaners into one easy-to-use product. With the touch of a button, you can use it individually or in time-saving combinations. One tool – four uses. The combo tool combines quick release, which makes changing channels on a squeegee easier, also includes our golden glove washer that wipes the toughest dirt, grime, and grease imaginable. One thing to keep in mind is that the squeegee is 2-inches longer than the washer.
