The Dyson Cinetic Big Ball Animal+Allergy vacuum is the first Dyson upright vacuum to have Dyson Cinetic science. It’s our biggest technological breakthrough since DC01: it has been engineered to solve the problem of cyclones clogging and losing suction. 35 Dyson Cinetic tips inside this machine oscillate 350 times every second. This means they can generate high centrifugal forces to separate the microscopic dust that clogs other vacuums. Because Dyson Cinetic science is so efficient, the Dyson Cinetic Big Ball Animal+Allergy vacuum doesn’t need to rely on filters to trap dust as other vacuums do, so there is no pre-motor filter. This means there are no dirty filters to wash or replace, and it never loses suction. The self-adjusting cleaner head has an active base plate that automatically adjusts the cleaner head height to seal in suction across all floor types, so it’s able to clean both carpets and hard floors throughout the home. With whole machine HEPA filtration, Dyson Cinetic science captures pollen, mold, and bacteria, and traps them within the bin. No other vacuum expels cleaner air. Size: 12.1 In..
