The Dyson Cinetic Big Ball Multi Floor vacuum is the first upright vacuum with Dyson Cinetic science. It's our biggest technological breakthrough since we invented cyclonic vacuum cleaners: engineered to solve the problem of filters clogging and losing suction. So it's the only vacuum cleaner with strong constant suction and no dirty filters to wash or replace. The self-adjusting cleaner head has an active base plate that automatically adjusts to seal in suction across all floor types. It's able to thoroughly clean both carpets and hard floors throughout the home. Whole-machine HEPA filtration ensures allergens and bacteria are trapped inside the machine, and not expelled back into the home. And with hygienic bin emptying, there's no need to get your hands dirty - just push the button to release the dirt.
