Dyson Cinetic™ science has revolutionised vacuum cleaner technology – it captures the microscopic dust that clogs all others. Dyson Cinetic™ science generates centrifugal forces of up to 313,000G flinging particles as small as pollen and mold spores from the air and into the bin. Each of the 35 Dyson Cinetic™ tips oscillate 350 times every second, preventing dust building up and blocking the airflow. Dust separation is so efficient there’s no need for a pre-motor filter, so it doesn't lose suction.
