A new idea
In 1978, James Dyson became frustrated with his vacuum cleaner’s diminishing performance. Taking it apart, he discovered that its bag was clogging with dust, causing suction to drop. He’d recently built an industrial cyclone tower for this factory that separated point particles from the air using centrifugal force. But could the same principle work in a vacuum cleaner?
He set to work. Five years and 5,137 prototypes later, he had invented the world’s first bagless vacuum cleaner.
