The Powr-Flite 13in. Zoom Ultra Lightweight 2-Speed Upright Vacuum with Lifetime Belt features a hard shell outer bag design yet weighs only 9 lbs. The lifetime belt protection includes Hail Sensor technology, which stops brushroll when it encounters a jam, protecting motor and belt. The chevron bristle, metal ball bearing brushroll provides an aggressive agitation for a brush-propelled feel. Replaceable brush strips ensure a longer brushroll life. The rubber squeegee allows ultimate bare floor cleaning, and the hard case bag design adds durability. The large 7.5-quart bag capacity means changing bags less often. HEPA filtration filters dust and allergens down to 0.03 microns for cleaner air. The self-sealing bag design prevents dirt from escaping during disposal The pigtail cord means less down time. LEED qualifying (low speed only), HEPA filtration < 70 dBA (low speed only).
