'''Dyson''' is a [[Great Britain|British]] appliances manufacturer. Its main products are [[vacuum cleaner]]s that use [[cyclonic separation]]. The founder, [[James Dyson]], used [[Centrifugal force|centrifugal]] particle separation after finding that to restore suction, the [[dust]] bag in his vacuum cleaner needed to be replaced – even when it was not full.
Initially manufactured in [[England]], the vacuum cleaner production has since moved to [[Malaysia]].
==History==
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. 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:
<blockquote>
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.
</blockquote>
Dyson developed 5,127 Dual Cyclone prototype designs 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.<ref>[http://www.themanufacturer.com/uk/content/6925/The_Manufacturer_Power_50_2006 The Manufacturer Power 50 2006]</ref> In 1986, a production version of the G-Force was first sold in [[Japan]].
In 1991, it won the International Design Fair prize in Japan, and became a status symbol there, after which the Japanese licensed and sold the product for $2,000 each.<ref>{{cite web | title = James Dyson: Business whirlwind | work = BBC News | url = http://news.bbc.co.uk/2/hi/business/1802155.stm | accessdate = 2007-06-28 }}</ref>
The biggest vacuum cleaner manufacturers refused to licence his technology, so Dyson decided to design, manufacture and advertise a vacuum cleaner himself. [[The Hoover Company|Hoover]] later admitted that it did consider buying the patent from James Dyson, but only to keep the technology out of the market.<ref>[http://www.dyson.com/nav/inpageframe.asp?id=DYSON/HIST/NEWPLACE]</ref>
Using the income from the Japanese licence, James Dyson set up the Dyson company, opening a research centre and factory in [[Wiltshire]], [[England]], in June 1993. His first production version of a dual cyclone vacuum cleaner featuring constant suction was the DC01, sold for [[pound sterling|£]]200. In their research for the vacuum cleaner, when Dyson asked people whether they would be happy with a transparent container for the dust, most respondents said no. Dyson and his team decided to make a transparent container anyway, primarily for advertising purposes.<ref>RGC Jenkins & Co., Trade Mark and Patent Attorneys [http://www.jenkins-ip.com/mym/spring2004/item_11.htm A Clear Bin Policy]</ref>
After the introduction of the DC02, DC02 Absolute, DC02 De Stijl, DC05, DC04, DC06 and DC04 Zorbster, the root<math>^8</math> Cyclone was introduced in April 2001 as the Dyson DC07, which uses seven smaller funnels on top of the vacuum.
===Production moves to Malaysia===
Initially, all Dyson vacuum cleaners and washing machines were made in [[Malmesbury, Wiltshire|Malmesbury]], [[Wiltshire]], [[England]]. In 2002, the company transferred vacuum cleaner production to [[Malaysia]]. As Dyson was the major manufacturing company in Wiltshire outside of Swindon, this move aroused some controversy, although in fairness planning permission to expand the Malmesbury site had been refused, effectively leading Dyson to look elsewhere. A year later, washing machine production was also moved to Malaysia.
Although nearly 800 manufacturing jobs were lost, Dyson states that the cost savings from transferring production to Malaysia enabled investment in R&D at Malmesbury head office, and that the company employs more people in the UK then before the move to Malaysia.<ref>BBC NEWS - [http://news.bbc.co.uk/1/hi/england/2282809.stm Dyson plant shuts up shop] (26 September, 2002)</ref>
==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.
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.
The powerful suction spins out larger dirt and debris. The shroud then filters out fluff and dirt. The fast moving air takes the smaller dirt and dust particles into the cones where the dirty air is accelerated to {{convert|900|mph|lk=on|abbr=on}}, spinning at over 324,000 [[Revolutions per minute|rpm]] in each cone.<ref>{{cite web | title = Eye Of The Cyclone: How does Dyson's Dual-Cyclone technology work? | work = IndustryWeek | url = http://www.industryweek.com/CurrentArticles/asp/articles.asp?ArticleId=571 | accessdate = 2007-06-28 }}</ref> Centrifugal forces of 200,000 ''[[g-force|g]]'' are exerted on the tiny particles moving in the 900 mph dirty air inside the cones. The momentum of the particles is so high, that cigarette smoke particles separate from the air at the narrow end of the cones and gather in the container. The use of centrifugal forces rather than fine filters, results in the Dyson maintaining suction, with no influence on the amount of dust that is collected in the container.
===Misleading Advertising===
The UK [[Advertising Standards Authority (United Kingdom)|Advertising Standards Authority]] (ASA) upheld that Dysons "No clogging. No loss of suction" advertising campaign was "misleading", as "Dyson's operating instructions indicated that the pre-motor filter should be washed periodically to prevent it from becoming clogged and to maintain the suction power of the cleaner".<ref>Advertising Standards Authority [http://www.asa.org.uk/asa/adjudications/Public/TF_ADJ_42594.htm ASA Adjudications - Dyson Appliances Ltd]</ref>
The claim of internal air speeds of 900mph was made by Dyson marketing and has been found to be wrong (hence it is no longer featuring in their marketing materials). The actual speed is closer to 90mph. {{Fact|date=July 2008}}
