Strong suction and light to maneuver, what more would you want from a vacuum? Radial Root Cyclone(TM) technology helps remove more dirt, dust and allergens from the home while the self-adjusting cleaner head automatically adjusts to seal in suction, even on hard floors. Dyson's reconfigured bristles dig deeper into carpets to remove more dirt. But what makes this vacuum really unique is the Ball(TM) technology. Core components are inside the ball, creating a lower centre of gravity allowing you to steer easily into difficult places. On a different level, an instant release wand helps you clean up high and down low, under furniture. This ball upright includes a combination tool, stair tool, multi angle brush, and stiff bristle brush.
