Even when the presser lid 260 is attached, the separate suction port 213 is open, so that external air can be sucked. Therefore, it is possible to continuously purify the external air sucked from the separate suction port 213 while preventing the odor of the dust stored in the dust storage member from diffusing.

  Moreover, in the said 2nd Embodiment, although the example which provides another suction inlet in the lower part of the front part 111 of the housing | casing 110 was demonstrated, this invention is not restricted to this, Like the separate suction inlet of 1st Embodiment, You may provide another suction inlet in the upper end part of a housing | casing. At this time, it is preferable that the separate suction port is provided along a surface inclined with respect to the surface including the opening of the dust container.

  Further, in the above embodiment, an example in which a streamer unit is provided has been described, but the present invention is not limited thereto, and if dust in the air can be sufficiently collected by a filter disposed inside the dust container, It is not necessary to provide a streamer unit. Moreover, you may provide the electric dust collection unit which electrically collects dust instead of a streamer unit.

  If the present invention is used, the work performed by the user can be simplified by performing the litter disposal work and the filter replacement work all at once.
