Dyson The original Root Cyclone™ cylinder 2L

The original Root Cyclone™ cylinder Patented Root12Cyclone™ technology maintains powerful constant suction.
Cleans under low beds and sofas.
All Dyson cleaners have lifetime filters. This means:
constant suction and high filtration
filtration of particles as small as cigarette smoke (0.1 micron)
no running costs
Dyson Root12Cyclone™ technology maintains powerful constant suction and removes more fine dust from the airflow than any other bag or “bagless” system, so the filters don't clog.
The intake nozzles of the DCO8 tools direct high velocity airflow down into the carpet pile to agitate and dislodge the dust.
DCO8 tools can be attached directly to the end of the hose, allowing you to clean confined spaces easily - such as the car or upholstery.
The suction release trigger reduces suction by 35%, so that you can clean curtains, upholstery or delicate rugs without them sticking to the cleaner. No need to bend down to adjust any dials or switches.
You can store the tool holster either on the main body or wherever you like on the hose, so that the stair, crevice and brush tools are always to hand.
