Root Cyclone™ + core separator
In our latest machines, Dyson engineers have combined Root Cyclone™ technology with a core separator – an extra cyclonic stage between the outer and inner cyclones – to separate particles as small as 0.5 microns from the airflow. You could fit 200 of these particles on a full stop.
First, dust is drawn into a powerful cyclone. Centrifugal forces of 500 G fling larger dirt, debris, fibres and pet hairs into the clear bin.
The air passes through here, while fibres and pet hairs that have escaped the outer cyclone are sieved out and directed back into the bin.
Finally, a cluster of smaller, faster cyclones generate centrifugal forces of up to 150,000 G – extracting particles as small as mould and bacteria.
