ABSTRACT:
A bagless vacuum cleaner includes a separating unit for separating dirt and dust from a dirt-laden airflow which is drawn in by the cleaner. The separating unit has a chamber with a collection area for collecting dirt and dust which is separated from the airflow. A base of the separating unit is movable between a closed position and an open position. The base may be released by a trigger and a linking mechanism. The releasing mechanism is operable to apply an opening force to the base to push the base open, thereby allowing a tightly fining seal to be fitted to the base.
