"Illuminated cleaner head reveals hidden dust on hard floors.2 A piezo sensor continuously sizes and counts dust particles – automatically increasing suction power when needed. LCD shows what’s been sucked up in real time, 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, provides up to 60 minutes of fade-free power, Dyson’s fully-sealed filtration traps 99.97% of microscopic particles and allergens as small as 0.1 microns, Carbon fibre filaments Black anti-static carbon fibre filaments to extract fine dust from hard floors."
