Patented cyclone technology
There are other cordless vacuums that are bagless. But with inefficient cyclones, dust can pass through onto the filter, clogging it and causing suction loss.
Dyson cordless vacuums use patented cyclone technology, just like our corded machines. Powerful centrifugal forces spin dust and dirt out of the air and into the bin, ensuring that high suction power is maintained.
This patented cyclone technology combines with the Dyson digital motor and a re-engineered nickel manganese cobalt battery to ensure that Dyson cordless machines provide powerful suction. From the moment you start cleaning, to the moment you finish.
