Dyson is a global technology company founded by Sir James Dyson known for inventing the world’s first bagless cyclonic vacuum cleaner. The First Idea: In 1978, James Dyson grew frustrated with his vacuum losing suction and discovered the dust bag was clogging. The Prototype: After 5,127 prototypes over five years, he successfully built a bagless vacuum using centrifugal force. Launch: He launched the G-Force in Japan in 1986, and later founded Dyson to release the iconic DC01 model in 1993.
