Abstract

A pleated filter (125) is provided higher than an upper opening (37) of a dust collecting unit (9). An introduction hole (165) is provided on the downstream side of the pleated filter (125). 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 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 (212a) is secured, whereby reduction in suction power over time can be suppressed.
