Abstract
A handheld cleaning appliance includes a dirty air inlet, a clean air outlet and separating apparatus for separating dirt and dust from an airflow in an airflow path leading from the air inlet to the air outlet. The separating apparatus includes a cyclonic separator having at least one cyclone and a collector having a wall and a base member, the base member being held in a closed position by a catch and being pivotably connected to the wall. The appliance further includes a main body which incorporates an actuator for operating the catch. The actuator has a slidably mounted rod which is movable between an inoperative position and an actuating position in which the rod contacts part of the catch so as to allow the collector to be opened for emptying purposes. This arrangement allows the catch to be released without the user actually touching the collector.
