ABSTRACT:
A dust and dirt separation assembly for use in a vacuum cleaner having a housing having a dirt collection chamber, a dirty air inlet, a clean air outlet, and an airflow path existing therebetween, a first separation means for separating articles of dirt from dirty air entering the housing, a filter element for separating smaller particles of dust from the dirty air, a selectively manually operable mechanical actuation mechanism including a snap-acting resilient element that changes from a first stable condition to a second condition when a sufficient force is applied, and an impact member actuable by the mechanical actuation mechanism to strike the filter element thereby dislodging dust particles therefrom to be collected in the dirt collection chamber.
