Bagless cyclonic action is a type of vacuum cleaner filtration system that uses a series of cyclones to separate dirt, dust, and other debris from the air. The air is drawn into the vacuum cleaner and passed through a series of cyclones, which spin the air at high speeds. This centrifugal force causes the heavier particles to be thrown to the outside of the cyclone, where they are collected in a filter bag or container. The lighter particles, such as dust and pollen, are carried further into the vacuum cleaner and are eventually expelled through the exhaust hose.
