James Dyson founded Dyson in 1991 after developing bagless vacuum technology.
Dyson’s breakthrough came from applying cyclonic separation to vacuum cleaners. Frustrated by declining suction in conventional machines as their bags filled, Dyson built thousands of prototypes before producing a commercially successful bagless design. The first widely marketed Dyson vacuum was the G-Force, launched in Japan in 1993.
The company was originally called Dyson Appliances Limited and later became Dyson Limited. James Dyson did not invent the household vacuum cleaner itself; his major contribution was developing and commercializing a bagless system using cyclonic technology. Dyson later expanded into hand dryers, fans, air purifiers and hair-care products.
