Dyson is a British appliances manufacturer. Its main products are vacuum cleaners that use cyclonic separation. The founder, James Dyson, used centrifugal particle separation after finding that to restore suction, the dust bag in his vacuum cleaner needed to be replaced – even when it was not full. Initially manufactured in England, vacuum cleaner production has since moved to Malaysia. In 1979, James Dyson bought what was then the top of the range vacuum cleaner. He became frustrated with how it rapidly clogged and began to lose suction so he emptied the bag to try to restore suction but this had no effect. Dyson opened the bag and noticed a layer of dust inside, clogging the fine material mesh. He resolved to develop a better vacuum cleaner that worked more efficiently. During a visit to a local sawmill, Dyson noticed how the sawdust was removed from the air by large industrial cyclones. He conjectured the same principle might work, on a smaller scale, in a vacuum cleaner. He... less
