A new idea
In 1978, James Dyson noticed how the air filter in the Ballbarrow spray-finishing room was constantly clogging with powder particles (just like a vacuum cleaner bag clogs with dust).
So he designed and built an industrial cyclone tower, which removed the powder particles by exerting centrifugal forces greater than 100,000 times those of gravity.
Could the same principle work in a vacuum cleaner? James Dyson set to work. 5 years and 5,127 prototypes later, the world's first bagless vacuum cleaner from Dyson arrived.
