Conventional vacuum cleaners rely on bags to trap dust and dirt. But when you start to use some bagged machines, dust can clog the tiny holes in the bag. Some ordinary bagless vacuum cleaners work in a similar way. They use a central filter to trap fine dust, which can clog too. Suction drops, leaving dust and dirt behind in your home.
Dyson's patented cyclone technology doesn't rely on a bag to trap dust and dirt. Instead, it spins the air so fast that centrifugal forces up to 100,000 times the force of gravity fling dust and dirt out of the air and straight into the clear bin.
Dyson engineers have combined Root Cyclone™ technology with a core separator - an extra cyclonic stage between the outer and inner cyclones - to separate particles as small as 0.5 microns from the airflow. You could fit 200 of these particles on a full stop.
