This 32" blue squeegee blade is made out of polyurethane, and is a universal rear squeegee blade on a 2 squeegee system. The front squeegee blade is slotted and allows solution into a vacuum chamber, and this rear squeegee then follows up behind leaving the floor completely dry after one pass. These universal squeegees fit onto our Dura 18 electric auto scrubber, Viper cord electric floor scrubber, the Viper battery scrubber, and the wheel powered auto drive floor scrubber. It is a great system for recovering floor soap or even stripping solution. When doing a tripping job with a auto scrubber make sure to thoroughly rinse all tanks, lines and squeegees so no stripper or wax is left behind!
