Therefore, the storing operation, that is, the holding operation can be performed very easily.

Also in this embodiment, as in the case of the above embodiment, when it is necessary to clean the groove portion while cleaning the floor,
Since the nozzle 30, that is, an accessory, can be taken out from the accommodating recessed portion 50 provided in the connection port body 13 and used while keeping the cleaning posture, the connection port body 13 can be sucked in whenever necessary as in the conventional case. Place it on the floor with it, or lean it against a wall, etc. to reach the position of the cleaner body 1, take it out from the accessory storage formed on the cleaner body 1, and return to the position of the cleaner body after use. It is possible to eliminate the inconvenience of storing it in the accessory storage portion, improve the usability, and improve the operability. Further, in the case of this embodiment, the nozzle 30 has the storage recess 5
Since it is housed in 0 and not exposed to the outside, it is possible to prevent the nozzle 30 from hitting something and falling during cleaning. Further, the accessory parts such as the nozzle 30 are not exposed and have a good appearance, and can be stored or held compactly.

In each of the above-mentioned embodiments, the nozzle has been described as an example of the accessory held by the holding means. However, it is also possible to hold a round brush, and for example, a holding provided on the connection port body 13. 4 is a holding means formed of the storage recess 50 shown in FIG.
The holding means composed of the holding pieces 25a and 25b facing each other is provided on both lower sides of the joint pipe portion 15b shown in FIG. 2 to make the former hold a nozzle as an accessory and the latter hold a round brush as an accessory. In this way, the connection port body 13 can be made to hold a plurality of accessory parts.
