The Dyson DC65 uses Radial Root Cyclone™ technology and a reconfigured brush bar to remove more dirt and dust from the home. It achieves this through the combination of Radial Root Cyclone™ technology and a self adjusting cleaner head which seals in suction across carpets and hard floors. The latest Ball™ technology allows easy steering into difficult places. Other vacuums have a choice of settings for different floor types. This means that when moving from one floor type to another, suction power can be wasted. DC65 has an active base plate which self adjusts to create optimal contact with every floor type. This reduces air leaks and retains more suction power at the cleaner head.
