A true commercial master floor nozzle with the necessary parts to move from hard floor to carpet to wet use by simply sliding in the appropriate blades. The wheels help the tool to move across both carpeted and hard floor surfaces when used with even the highest performance vacuums. Ideal for rubberized floor surfaces where traditional floor brushes become hard to push. The 18cleaning width covers large surface areas quickly. The commercial tool comes with a 1.5Neck, fitting most backpack brands, canister brands, and commercial vacuums
