At this time, the main body 450 may be telescopic so that the length of the main body 450 can be expanded or contracted.

For example, the main body 450 includes a first body 451, a second body 452 slidably coupled to the first body 451, a second body 452 coupled to the first body 451, And a third body 453 slidably coupled to the second body 452. [

Here, the slide structure can employ various known structures and is not particularly limited. With such a configuration, the cleaning efficiency and usability of the multi-purpose suction accessory 440 can be further increased.

Although the technical idea of the present invention has been described above with reference to specific embodiments, the scope of rights of the present invention is not limited to these embodiments. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims and their equivalents.
