Highlights The only vacuum with no maintenance and no loss of suction. JD Powers 2017 Highest Customer Satisfaction with Canister Vacuums. 35 oscillating tips for powerful suction. Self-rights, self-adjusts. No dirty filters to wash or replace. One click bin emptying. Description The Dyson Cinetic Big Ball canister features Dyson Cinetic™ science, our biggest technological breakthrough since we invented cyclonic vacuum cleaners. The vacuum is engineered to solve the problem of filters clogging and losing suction. It’s the only vacuum cleaner with strong constant suction and no dirty bags or filters to wash or replace. The Dyson Cinetic Big Ball canister vacuum features monostatic, self-righting technology. The vacuum lies on a single stable resting point assembled in a spherical array. With the heaviest components near the floor, and a curved body with a low center of gravity, whenever the vacuum is displaced from its resting position, gravitational force will automatically return it upright. Or more simply, when it’s knocked over, it gets back up. The Dyson Cinetic Big Ball canister vacuum features a new bin emptying mechanism. You can hygienically drive out trapped dust and debris with just the push of a button. There’s no need to touch the dirt. While cleaning, an articulated handle rotates in three directions allowing 360° articulation for easy, versatile and greater control – all around the home, from floors to furniture to even high corners.
