The PurePower™ PP600 power unit combines powerful suction and unmatched filtration, to remove dust and other allergens from your home. It comes with sealed HEPA combined with 600 air watts of power to give you the cleanest indoor air. It features a sleek design that can fit into compact spaces and works well for homes up to 7000 sq ft. The PP600 operates quietly and is virtually silent to you when vacuuming if it is installed in a basement or garage. With unmatched filtration, you won't be spreading the dust around - because microscopic dust particles are exhausted to the exterior of your home.
