Abstract:
A surface cleaning apparatus comprises a filtration apparatus comprising a cyclone downstream from the dirty air inlet and an openable filtration chamber comprising a screen downstream from the cyclone and upstream from the suction motor. The filtration chamber is accordingly a separate volume to that of the cyclone chamber and accordingly may be accessed to clean the screen independently of opening the cyclone chamber.
