The Dyson DC11 Allergy is an extremely powerful yet compact vacuum cleaner. It takes up only half the space of many conventional vacuum cleaners, as its fully extendable wand disappears into the handle when collapsed, and the hose coils tightly around the housing. The patented root cyclone technology is the heart of the DC11 Allergy: the air is forced through twelve small cyclones to vacuum dust and dirt at extremely high and constant suction. You can easily and hygienically empty the transparent collection bin at the press of a button. And you can use the newly developed turbine air head on all surfaces: the brush rollers rotate over carpets and can be switched off on smooth floors. Thanks to its excellent HEPA filtration the Dyson vacuum cleaner is especially suitable for allergy sufferers.
