Accordingly, when both of the first and the second cleaning surfaces 10 and 20 are planar to each other such that both are positioned at an angle ⁇ 1 of zero degrees with respect to each other, by the urging force of the elastic member 240 , the interior angle ⁇ 2 between the first and the second assembly bodies 210 and 220 is automatically turned to 180 degree, and therefore, the second assembly body 220 is turned horizontal with respect to the first assembly body 210 . When the interior angle ⁇ 2 becomes zero degrees, the second assembly body 220 is folded onto the first assembly body 210 .
  • the user of the vacuum cleaner can clean both of the first cleaning surface 10 and the second slanted cleaning surface 20 in one cleaning operation or simultaneously.

By fixing the interior angle ⁇ 4 to 90 degrees, the slope angle ⁇ 3 between the first and the second cleaning surfaces 30 and 40 can be maintained at 90 degrees, and therefore, the interior angle ⁇ 4 does not change in operation. Furthermore, by doing as described above, the elastic member 240 (see FIG. 2 ) may be omitted from the suction port assembly 300 for the stairway cleaning operation, because the interior angle ⁇ 4 is not required to be automatically adjusted.
  • the suction port assembly 300 can be stowed with increased convenience when not in use, because the second assembly body 320 can be turned 90 degrees toward the first assembly body 310 so that the second assembly 320 can be folded onto the first assembly body 310 .

  • the slope angle ⁇ 3 and the interior angle ⁇ 4 are fixed to 90 degrees, the user does not need to force the extension pipe 140 to vary the interior angle ⁇ 4 in accordance with the slope angle ⁇ 3 .
  • the suction port assembly 300 is moved in the direction of arrow G or arrow H, and cleans the first and the second cleaning surfaces 30 and 40 .
  • the rest of the cleaning operation will be omitted for this is similar to that which has been described above with reference to FIGS. 1 and 2 .
  • the vacuum cleaner having a suction port assembly according to the present invention is especially effective for the cleaning of stairways with slope angles of 90 degrees, or carpeted areas which attract more dusts and therefore require frequent cleaning operations.
