Dyson In 1978, frustrated with traditional bag vacuum cleaner constantly clogging and not effectively picking up dust and dirt, James Dyson was determined to develop the technology for the first vacuum cleaner with constant suction. He found that by making the air stream spin, dirt and debris are subjected to centrifugal force and are thrown out of the air. A cone shape speeds up the spinning air to create greater centrifugal force, so even finer dust particles are thrown out of the air. Because the airflow is unobstructed, there’s nothing to clog. The result of Dyson’s cyclone technology, combined with his numerous other patented technical advances, is the first vacuum that doesn’t lose suction. 11-19-05 |
