Take the difficulty out of cleaning by revving up the Hoover U6485900 Anniversary WindTunnel upright vacuum cleaner. This machine is self-propelled to enable easy movement around the floor. This Hoover vacuum uses a traditional bag system to filter dirt and clean the home. Included with the original purchase is a HEPA bag, which is designed to be sensitive toward the collection of allergens like pet dander. The ergonomically designed handle and height adjustment option make the unit comfortable to use for the average person as well. Essentially, this is a vacuum that takes on the brunt of most tasks. The Hoover WindTunnel moves on its own, while users simply drive the cleaner. Check the indicator to see when it is time to empty the HEPA filter bags. Enjoy the extended length of the 29-foot power cord, as going from room to room without stopping to unplug and re-plug makes housework less frustrating. Whiz through chores with minimal risk of back strain by letting the self-propelled system take over.Windtunnel technology was originally designed in 1997 to pull dirt and debris out of the carpet until completely bagged. Other upright vacuums would only scatter these minute particles of unwanted filth back to the surface. This unique design creates a type of controlled tornado. It forcefully pulls unwanted particles out of carpets through the filters until they are safely bagged away.The self-propelled movement applies to forward and reverse directions. Little manual muscle power is required to maneuver this Hoover vacuum upright model, which means it is perfect for individuals who find it difficult to steer a heavy vacuum. The HEPA bag traps 99.97 percent of pollen, dust, and other particles. These types of filters are scientifically designed to make them a healthier choice over bagless canister vacuum cleaners. The embedded dirt finder lights up when suction has bagged all of the debris found in a location. This is very helpful because it ensures complete cleanliness of the carpet and lets the user know what areas are finished. All unwanted material is filtered and bagged. A light indicates a full bag. For easy viewing in darker areas, this Windtunnel upright vacuum has a headlight. Thanks to the height adjustment and edge cleaning feature, you are able to clean all types of flooring, picking up more in the corners and sides of walls. There are several helpful accessories included. The air powered hand tool is light and efficient. Two extension wands, a crevice tool for tight spaces, and an upholstery tool with a brush for furniture is helpful with cleaning. The hose reach is eight feet long. All Hoover accessories are interchangeable.
