Patent ID: 7811349

Claim:
A vacuum cleaner comprising: a cleaning head assembly having a suction nozzle; a suction source; and a cyclone module assembly in fluid communication with the suction nozzle and the suction source, and comprising: a cyclone separation chamber for separating dust and debris from air with the generation of a cyclonic airflow vortex forming a vortex tail, the cyclone separation chamber having an inlet opening in fluid communication with the suction nozzle through the working air path, an outlet opening for discharging cleaned air and a particle discharge outlet for discharging dust and debris separated from air; a dirt cup removably mounted to the cyclone separation chamber and in fluid communication with the particle discharge outlet for collecting dust and debris that is separated from the air in the cyclone separation chamber; and a vortex stabilizer selectively mounted with respect to the cyclone separation chamber for movement between a closed position at a predetermined location with respect to the cyclone separation chamber and an open position away from the closed position for access to the cyclone separation chamber to remove any accumulated dust and debris that remains on the vortex stabilizer after a cleaning operation.
