Description & Features+

Strongest Suction of any other vacuum*.
*Suction tested against upright market to ASTM F558 at the cleaner head, dust-loaded.
Radial Root Cyclone™ technology:
By arranging the inner cyclones in a radial formation, airflow can be channeled directly through the centre of the cyclone assembly once it has passed through both stages of cyclone separation. This improves flow efficiency, preserving air pressure and maximizing suction. DC66 has Dyson's most advanced Radial Root Cyclone™ technology. Dyson engineers have further refined the cyclone inlets and vortex fingers to generate more suction through the machine - to remove more dirt and dust from the home.
Dyson vacuums are engineered to remove allergens:
For a vacuum cleaner to be effective at removing allergens, it needs more than just HEPA filtration. Just as important are powerful suction, high dust removal at the cleaner head, cyclones that capture particles down to 0.5 microns and hygienic bin emptying.
