The Dyson Big Ball Turbinehead has powerful Dyson suction to remove hair and dirt from every floor type. Self-righting technology Dyson Big Ball canister vacuums are monostatic: they have a single stable resting point. Dyson engineers made this possible using a complex configuration of the vacuum s components. By assembling them in a spherical array, with the heaviest components near the floor, we created a curved body with a low center of gravity. This means that whenever the vacuum is displaced from its resting position, gravitational force will automatically return it. Or more simply, when it s knocked over, it gets back up. Dyson Big Ball canister vacuums feature a new bin emptying mechanism so you can hygienically drive out trapped dust and debris with just the push of a button. With advanced whole-machine filtration and 4 additional tools for versatile tasks, the Turbinehead tool automatically raises and lowers to seal in suction across carpets, rugs, and hard floors.
