Dyson reveals microscopic dust : The most powerful, intelligent cordless vacuum. Measures microscopic dust particles: A piezo sensor continuously sizes and counts dust particles – automatically increasing suction power when needed. Root Cyclone technology : 14 scrolled cyclones generate forces of up to 100,000g to capture dust and debris from the airflow, so there’s no loss of suction. Multi-stage filtration : Dyson’s fully-sealed filtration traps 99.99% of microscopic particles and allergens as small as 0.3 microns – and expels cleaner air. Automatically deep cleans carpets : In Auto mode, Dyson DLS technology inside the High Torque cleaner head monitors brush bar resistance 360 times a second, intelligently adapting power across different floor types.
