Using Cyclonic suction, the Hoover U5189-900 vacuum spins dirt and dust right out of the air. This bagless vacuum never loses suction, providing sustained cleaning power every time you use it. Easy empty dirt cup means no bags and no mess. Telescoping handle adjusts to varying heights for convenient use and storage. The 8 foot hose and extension wands give you a 10 foot cleaning reach. Disclaimer: Suction stays constant for up to 10 ounces of dirt, as tested by an independent laboratory by using ASTM F558 test method and a dirt composition comprised of 70% mineral dust, 20% cellulose and 10% fibrous material.
