摘要：PROBLEM TO BE SOLVED: To provide a vacuum cleaner equipped with a pneumatic mechanism for removing dirt and debris from pores of a filter in order to enhance filter cleaning efficiency and extend filter service life. SOLUTION: The 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) a first position wherein dirt and debris are captured in the dirt collection vessel; and (b) a second position wherein clean air is drawn through at least a portion of the filter to clean the filter. The selective displacing of the flow control valve assembly between the first and second positions is automatically carried out by an activator. COPYRIGHT: (C)2008,JPO&INPIT
