Abstract
A surface cleaning apparatus comprises a filtration apparatus comprising a cyclone and an openable dirt collection chamber in communication with the cyclone dirt outlet. The dirt collection chamber has an openable end portion that comprises a wall that is intersected by the longitudinally extending axis, and when the end portion is in an open position, the cyclone chamber has an absence of any member having a larger diameter than the vortex finder whereby the dirt collection chamber and the cyclone are concurrently emptyable when the dirt collection chamber is opened.
