About Dyson VacuumsJames Dyson started work on the cyclonic vacuum in 1978.  Dyson is a home appliance founded by an engineer who wanted to improve the suction of household vacuums.  James Dyson found that as a vacuum filled with dust, the amount of suction dropped.  He wanted to find a way to maintain close to 100% suction even as the dust bag / container filled.  After many prototypes and refinements he started his own company and produced the first Dyson Dual Cyclone DC01 in 1993."TheVaccumCenter.com  loves Dyson engineering and Dyson performance."
