Dyson Root Cyclone
From Wikipedia, the free encyclopedia
The Dyson Root Cyclone is a home vacuum cleaner developed by James Dyson, a British inventor. It is marketed as "the first vacuum cleaner that doesn't lose suction."[1]

[edit] History
As a six-year-old Dyson had to help his mother with household chores. He noticed frequently as he vacuumed that he had to stop to clean out the sweeper. As with all vacuums, the bag got clogged and the vacuum lost suction.
In 1978 while renovating his country house in the Cotswolds, Dyson visited a sawmill where he observed sawdust being sucked into a cone using a spinning column of air. Not having a clue what one was, but refusing to pay £75,000 to have one installed in his own factory, Dyson decided he would make one of his own.
According to @Issue: The Journal of Business and Design (vol. 8, no. 1), the source of inspiration was in the following form:
In his usual style of seeking solutions from unexpected sources, Dyson thought of how a nearby sawmill used a cyclone—a 30-foot-high cone that spun dust out of the air by centrifugal force—to expel waste. He reasoned that a vacuum cleaner that could separate dust by cyclonic action and spin it out of the airstream would eliminate the need for both bag and filter.[2]
Dyson developed and built 5,127 Dual Cyclone prototype cleaners between 1979 and 1984. The first prototype vacuum cleaner, the G-Force, was built in 1983 and appeared on the front cover of Design Magazine the same year. In 1986 a production version of the G-Force was first sold in Japan.
In May 1993 the first production version of a dual cyclone vacuum cleaner featuring constant suction, the Dyson DC01, was sold for £200. After the introduction of the DCO2, DCO2 Absolute, DC02 De Stijl, DC05, DC04, DC06 and DC04 Zorbster, the Root8 Cyclone was introduced in April 2001 as the Dyson DC07, which uses seven smaller funnels on top of the vacuum.
[edit] Cyclone technology
A Dyson cyclone works by employing cyclonic separation, which spins air at high speed. Dirt and dust are thrown out of the airflow and collected in the bin, not on filters or in bags.
Root8 Cyclone technology works by building on dual cyclone technology. On top of the vacuum chamber, seven funnel-shaped channels were added that force air to travel in higher curvature cyclones than in the initial cyclone, creating higher centrifugal force, allowing smaller particles to be captured before the air is expelled.
Summary
- Powerful suction spins out larger dirt and debris.
- The shroud filters out fluff and dirt.
- Centrifugal forces of 200,000 g spin out the finest harmful particles.
- Fantastic on pet hair.

[edit] Products
The Root Cyclone technology is available in:
- DC07. Upright model with new Root Cyclone technology
- DC08. New cylinder revision incorporating Root Cyclone technology
- DC08TW. TW is short for "Telescope Wrap". The wand handle is telescopic and the hose wraps around the machine.
- DC11. First cylinder model to incorporate the telescopic wand handle and hose wrapping. Parallel root cyclone packs.
- DC14. Revision of upright vacuum cleaner with lower center of gravity and telescopic wand.
- DC15. Latest product. It has a ball instead of a wheel which, in conjunction with a universal joint on the cleaner head, makes it possible to steer the machine simply by twisting the handle to the right or left.
In addition, similar technology was used in Contrarotator, the world's first washing machine with two drums rotating in opposite directions, which was first available in November 2000.
