The licensing deal James Dyson made with Fantom Technologies probably would have continued (and we would not have Dysons in America now) if Fantom's greed wasn't so high. When Mr. Dyson designed the MEMA filters for the DC04, Fantom had the right to use the design. They had no interest in a washable pre-motor electrostatic/foam filter since they were in the business of Selling HEPA exhaust filters. For $75 each. With no pre-motor filter, the exhaust filters 'filled up' quickly. Mr. Dyson did not sign another deal with them, once the first deal was up (ten years I believe), and Fantom lost the right to the dual cyclone technology.
I like to think that had Fantom not gone out of business, they would be making an American version of the ball design vacuums. Better brush rollers for American carpets.
