The new DC22 Dyson Baby vacuum cleaners combine Root Cyclone™ technology with a core separator - an extra cyclonic stage between the outer and inner cyclones which separates particles as small as 0.5 microns from the airflow. What makes the new Dyson cylinders different? Concentrated technology Dyson Baby™ can be stored in just half the space of conventional cylinders and it has the most advanced Dyson cyclone technology for even greater efficiency. Hygienic bin emptying Dyson vacuum cleaners don't use bags, so there's no extra costs. And they're hygienic to empty. Just press the button. The problem with conventional cylinders Unwieldy wands and hoses make other vacuums hard to store, and replacement bags can cost as much as $500 over the lifetime of a bagged machine.
