Dyson's lightest cordless hoover with a high suction power of 150 AW. Up to 60 minutes run time2 including rechargeable battery (second battery sold separately). Floor nozzle with dust detection technology makes invisible dust on hard floors visible - so you don't miss a thing. A piezoelectric sensor continuously calculates the number and size of dust particles vacuumed up - and automatically increases the suction power if necessary. The trigger no longer needs to be held down. This makes it easy to change hands when manoeuvring around obstacles.
