That is, the suction parts 81, 82, 83 and 84 of the rotating body 80 may be closed, and air and dirt may be suctioned only through the crevice member 310, so as not to cause loss of suction force.
  • the crevice member 310 is shown to describe a part that may be coupled to the opening 55, however, the present disclosure is not limited thereto. Any form or shape of the part that has an opening to suck the air in may be coupled to the opening 55.
  • FIG. 14 is a view illustrating a multipurpose suction accessory of a vacuum cleaner according to a fourth embodiment of the present disclosure.
  • a multipurpose suction accessory 440 includes a cylindrical main body 450 coupled to the handle pipe 30 and a cylindrical rotating body 80 rotatably coupled to the outside of the main body 450.
