ABSTRACT:
A floor cleaning apparatus includes a housing and a dirt collection vessel carried on that housing. The dirt collection vessel includes a dirty air inlet, a clean air inlet, a dirt collection chamber and a clean air outlet. A filter is received in the dirt collection vessel. A suction generator is carried on the housing. The floor cleaning apparatus also includes a flow control valve assembly. The flow control valve assembly is selectively displaceable between a first position wherein dirt and debris are captured in the dirt collection vessel and a second position wherein clean air is drawn through at least a portion of the filter to clean the filter. An activator is provided for automatically displacing the flow control valve assembly between the first and second positions.
