Delivering 200 air watts of suction power, Dyson's Slim upright vacuum cleaner features advanced Root Cyclone technology to ensure no loss of suction. Dyson proves no loss of suction using the IEC 60312 Cl 2.9 test standard. Designed for all floor types, the unit's motorized brushbar can be turned on to remove dirt and pet hair from carpets, or turned off to protect rugs and delicate floors. It also comes equipped with a quick-draw Telescope Reach, which extends instantly for stairs and high-reach cleaning. Thanks to the vacuum's money-saving, lifetime HEPA filter, air expelled from the unit contains up to 150 times less mold and bacteria than common breathing air. Thoughtfully designed, the unit's hygienic 4/9-gallon bin empties without ever having to touch the dust--simply push the button. Furthermore, Dyson upright vacuums are the first and only vacuums certified asthma friendly by the Asthma and Allergy Foundation. Other highlights include a 25-foot cord, a lightweight design at 15-4/5 pounds, and effortless steering for simple maneuverability and cleaning in tight spaces. The vacuum cleaner measures 16-1/3 by 12 by 43-2/3 inches and carries a five-year warranty.
