Abstract (en)
Dust is trapped in a main dust collecting chamber (21) by selecting a cleaning state through a switching mechanism (58) where a switching valve (48) provides communication between the main dust collecting chamber (21) and the upstream side of an electric blower (5) while an outside air incoming valve (52) is closed to cut off the communication with outside air. The dust trapped in the main dust collecting chamber (21) can be transferred to the auxiliary dust collecting chamber (22) by selecting a dust transfer state through the switching mechanism (58) where the switching valve (48) provides communication between the auxiliary dust collecting chamber (22) and the upstream side of the electric blower (5) while the opening-closing valve (41) provides communication between the main dust collecting chamber (21) and the auxiliary dust collecting chamber (22), and the outside air incoming valve (52) is opened to introduce outside air into the main dust collecting chamber (21), which can limit the reduction in suction power over time.
