One of the most fun inventions of my lifetime is the Mini.

Autobiography
Dyson James; Giles Coren (1997). However no manufacturer or distributor would handle his product in the UK as it would disturb the valuable market for replacement dust bags so Dyson launched it in Japan through catalogue sales. The cyclone idea came from the spray-finishing room's air filter in his Ballbarrow factory.

He is best known as the inventor of the Dual Cyclone bagless vacuum cleaner which works on the principle of cyclonic separation. Sir James Dyson (born 2 May 1947) is a British industrial designer and founder of the Dyson company.
