About Dyson and its products
It creates and sells household appliances such as vacuum cleaners, air purifiers, hand dryers, bladeless fans, heaters, hairdryers, and lights. Dyson has created a number of fundamental technologies for use in its products, including the design and manufacture of its own specialized motors.
The Dyson Root Cyclone technology is used in all Dyson vacuum cleaners beginning with the DC07. The improved “Root Cyclone & Core Separator,” also known as “Radix Cyclone,” “Intermediary Cyclone,” or “Level 3 Root Cyclone Technology,” is used in the DC17, DC22, and DC23. The majority of the current range employs “2 Tier Radial cyclones,” which are made up of two cascaded levels of cyclonic separators that remove dirt and dust without the use of a bag or filter.
