The bases of that claim are from the advanced Root Cyclone technology that is used to create the suction and filtration of the dirt particles. This technology was developed thirty years ago by James Dyson. At present there are 820 patents for the different components and parts for this technology that Dyson has developed. The concept is simple, spin the air at a very high speed and the dirt will collect on the sides of the container. With the spinning container shape like a cone, all the dust and debris will be channeled to a collection bin that was designed for easy cleaning. With the debris removed from the air, it would remain unobstructed and the pressure would never decrease or become clogged. This is one of the few items that are truly as advertised and tested by all known consumer magazines; this Dyson slim is designed to never clog.

Other nice accessories designed into this model are the ability to turn off the main brushes so bare or hard wood floors can be cleaned without any worry of scratches been left behind after cleaning. The HEPA filter is so efficient that it is recommended to be cleaned every few months, unlike other vacuum cleaners that at times need theHEPA filter cleaned every time they are used to maintain suction power. The Asthma and Allergy Foundation of America has even certified this model as ?asthma friendly? because of the air filtration system.

There are many reasons to consider the Dyson Slim model vacuum when making your next purchase including powerful, light weight and performance.
