Dyson’s most efficient cyclones capture more dust, dirt and microscopic particles than any other cyclone.Other vacuums lose suction, leaving more and more microscopic dust particles and allergens in your home. But with Dyson Cinetic™ vacuums, 36 Dyson Cinetic™ tips oscillate at up to 5000Hz, separating the microscopic dust that clogs other vacuums. There’s no need to wash or replace a filter, and there’s no loss of suction.Dyson have engineered the only vacuum that gets back up when toppled. Others vacuums fall down and stay down. Only Dyson Big Ball cylinder vacuums pick themselves up.Dyson Big Ball Cylinder vacuums also feature an articulated handle for easy, versatile cleaningThe wand’s handle now rotates in three directions, allowing full 360° articulation for greater control.There is also a larger, high-capacity bin which is 33% bigger than previous Dyson Cinetic™ cylinder vacuums.
