The 94555 is designed as a cost effective vacuum tool for dramatically reducing allergen promoting dust mites， dust mite residue， pet dander and other similar materials which can collect in the surface of a mattress， bedding， or other cloth covered surfaces like upholstered furniture. The vacuum nozzle uses the power of your central vacuum to spin a specially designed agitator that vibrates the cloth surface to lift the allergens into the air stream where they can be pulled away to be captured by your vacuums filtration system. The pivoting shoe design of the 94555 nozzle keeps the agitator parallel to the surface positioning the agitator for optimum results. The soft thermo-plastic paddles are molded in white to insure the tool will not color， discolor， or damage the surface of the mattress， bedding， or cloth surface as it gently by effectively reduces the allergens trapped on the surface.
