Bagless dirt collection meets on-the-go versatility in this powerful Hoover WindTunnel upright vacuum. Designed for a wide range of floor types, the 12 amp machine adjusts for bare floors or five heights of carpet with a sliding knob on the 15-inch nozzle. Hoover builds in a special duct system to keep particles from returning to the floor and a bristled brush roll to agitate dirt out of carpet fibers.
