Those who own them swear by them. Introducing a revolution in canister vacuum engineering. The Dyson Cinetic™ Big Ball Multi Floor has no filters to wash or replace, self-rights when toppled, and ejects trapped dust and dirt all while maintaining strong suction. Dyson Cinetic(TM) tips separate the microscopic dust that clogs other vacuums and dust separation is so efficient that there's no need to wash or replace a filter. This Dyson also self-adjusts to clean every floor type and features a turbine head tool that automatically raises and lowers to seal in suction across carpets, rugs and hard floors. It captures microscopic particles including allergens and bacteria with a 2 tier radial cyclone that generates higher centrifugal forces and expels cleaner air than the air you breathe. Includes an articulating hard floor tool; soft dusting brush; combination tool; stair tool; and quick release/uni fit adapter.
