Made from the original Starfiber microfiber, this dusting pad is designed for dry dusting on both hardwood and hard surface floors. Its Super Electrostatic Action attracts and lifts dust, pet hair, microparticles, and common household allergens from your floor's surface. The combination of special microfibers engineered into this pad creates the unique static charge which causes dust and debris to be attracted to the pad's fibers. And since the pad is reusable and washable up to 300 times, it is more economical than disposable dry dusting pads. The microscopic fibers in this pad are safe for all floor surfaces - they will not scratch. Fits 4 In. x 15 In. mop head. Dusting pad - 6 In. x 17-1/4 In. Replacement cleaning pad for Model No. WM710013384, WM710013385, and WM710013350 floor care systems.
