Abstract: In a suctioning state, even if the amount of dust trapped in a dust collecting unit in a main air passage is increased, air suctioned from a hose connection port is branched into a first half passage and reduction in the suction air amount can be suppressed. When the suctioning state is switched to a dust moving state by switch means, the dust trapped in a pleated filter is moved to the dust collecting unit, increase in the air passage resistance at the first half passage side caused by clogging of the pleated filter can be suppressed, and reduction in suction power over time can be suppressed. Since an upper air passage and lower air passage are provided in the lid body, the dust collecting unit is exposed with the lid body opened, whereby maintenance performance of the dust collecting unit is improved.

Abstract: A pleated filter is provided higher than an upper opening of a dust collecting unit. An introduction hole is provided on the downstream side of the pleated filter. When switching to a dust moving state, the outside air introduced from an introduction hole spreads to the entirety of the pleated filter when passing through the pleated filter and evenly cleans dust adhering to the entirety, and when micro dust removed from the pleated filter is moved to the dust collecting unit, this movement is supported by gravity by using the weight of micro dust. The pleated filter is prevented from being clogging by reliably moving micro dust removed from the pleated filter to the dust collecting unit, and when switching to a suctioning state, a suction air amount to pass through the first air passage is secured, whereby reduction in suction power over time can be suppressed.

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