All others lose suction. Only Dyson Cinetic™ science doesn't.1
Unlike all other vacuums, this one doesn't lose suction. It's because of the new, revolutionary Dyson Cinetic™ science – it captures the dust that clogs others. It doesn’t have any dirty filters to wash or replace. And it has whole-machine HEPA filtration. There's also a Tangle-free Turbine tool to remove dirt and hair from carpets and upholstery, 4 additional tools + tool bag worth $184.95.
