The Dyson Small Ball Upright Vacuum has the most powerful suction of any lightweight vacuum. It weighs just 12.15 lbs, so its easier to carry around the home and lift up stairs. With a retractable handle, it takes up to 50% less storage space than a full-size upright vacuum. The self-adjusting cleaner head automatically seals in suction across carpets and hard floors. It also has carbon fiber filaments on the brush bar, so it captures fine dust from hard floors while the direct drive motor pushes bristles deeper into carpets for a more thorough clean. Dysons patented Ball™ technology means its easy to maneuver around furniture and obstacles. It includes a 5-year warranty covering parts and labor. Suction tested to ASTM F58 at the cleaner head, dust-loaded.
