DESC: Equipped with Dyson Ball technology, this upright vacuum cleaner sits on a ball for easy twisting and turning around furniture and obstacles--no more missed angles or tiresome back-and-forth vacuuming. The ball also encapsulates the machine's 11 amp motor, creating a low center of gravity for even easier maneuverability. The vacuum cleaner uses Root Cyclone technology to separate dirt from the air by centrifugal force, which ensures efficient cleaning with no clogging or loss of suction. Effective for use on 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 delicate rugs and floors.
