Amazon reviews the Hoover U5750-900 Windtunnel upright vacuum cleaner: The Hoover U5750-900 Windtunnel upright vacuum cleaner picks up dirt other vacuums would miss and captures it inside two sealed, hygienic chambers rather than a messy bag. Three filters–a prefilter, an anti-allergen HEPA cartridge filter, and a final filter–ensure that clean air returns to the room. The twin chambers of the dirt cup are easily removed for emptying. All three filters can be rinsed, and the final filter can be washed. Accompanying the Hoover U5750-900 Windtunnel vacuum is a powered hand tool for stairs, upholstery, and automobiles. Two other tools–an upholstery nozzle and a dusting brush–are included and can be stowed, along with the hand tool, in a handy compartment. Other features of the 44-inch-high vacuum include a headlight to illuminate the 15-inch cleaning swath, a carpet height adjustment, edge groomers to clean along baseboards, and a soft bumper to protect furniture. The vacuum assembles with four screws (included).”
