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 vacuumâ€™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 itâ€™s knocked over, it gets back up. Hygienically Ejects the Dirt - Dyson Big Ball canister vacuums feature a new bin emptying mechanism. You can hygienically drive out trapped dust and debris with just the push of a button. Thereâ€™s no need to touch the dirt. Articulated Handle for Easy, Versatile Cleaning - The wandâ€™s handle rotates in three directions, allowing 360Â° articulation for greater control â€" all around the home, from floors to furniture and even high corners. Includes a 5-year warranty covering parts and labor. Color: Yellows / Golds.
