Abstract (en)
In a suctioning state, even if the amount of dust trapped in a dust collecting unit (9) 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 (126) is moved to the dust collecting unit (9), increase in the air passage resistance at the first half passage side caused by clogging of the pleated filter (126) can be suppressed, and reduction in suction power over time can be suppressed. Since an upper air passage (282) and lower air passage (283) are provided in the lid body (3), the dust collecting unit (9) is exposed with the lid body (3) opened, whereby maintenance performance of the dust collecting unit (9) is improved.
