Dyson Ltd is a British technology company that designs and manufactures vacuum cleaners, hand dryers, bladeless fans, and heaters. It sells machines in over 70 countries and employs more than 7,000 people worldwide.
A Dyson vacuum cleaner uses cyclonic separation to remove dust and other particles from the air stream. Dirty air enters a conical container called a cyclone, where it is made to flow in a tight spiral. Centrifugal force throws the particles out of the airflow onto the wall of the container, from which they can fall into a bin. The vacuum cleaner uses several stages of cyclones. Dyson states that centrifugal forces can reach up to 150,000 g
