Those how own them swear by them. The Dyson Bagless Multi Floor Big Ball Turbinehead Canister Vacuum features 2 Tier Radial™ cyclones that generate powerful centrifugal forces, capturing more dust and allergens. And, after collecting all that dirt, Dyson's new bin emptying mechanism uses a silicone wiper that slides down the shroud to hygienically drive out trapped dust and debris. With improved stability, Dyson Big Ball canister vacuums manoeuvre easily around obstacles and corners and if they do topple, they pick themselves up. Features include carbon fibre filaments that pick up fine dust while stiff nylon bristles help remove ground-in dirt; an articulated handle that easily rotates in three directions, allowing full 360° articulation for greater control and easy, versatile cleaning; a 56% bigger debris bin than previous Dyson Cinetic™ canister vacuums; quick-release tools that allow you to smoothly change tools between tasks; and a longer wand that extends up to 1.25m to clean hard-to-reach places.
