1. A vacuum cleaner, comprising:
- a suctioning nozzle that suctions in air including dust;
a height adjusting device that adjusts a height of the suctioning nozzle;
a manipulating part that manipulates the height adjusting device;
a position sensing part that senses the height of the suctioning nozzle adjusted by the height adjusting device; and
a display part that displays the height of the suctioning nozzle sensed by the position sensing part, wherein the height adjusting device comprises;
a height adjusting part that adjusts the height of the suctioning nozzle;
a rotating member coupled to the height adjusting part, the rotating member being configured to rotate together with the height adjusting part;
a cam coupled to the rotating member to rotate the rotating member, the cam including a rotating shaft that extends outward therefrom; and
a transferring part that transfers a manipulative force from the manipulating part to the cam, wherein the position sensing part comprises a rotating part that includes a recess formed on a first surface that faces the cam, wherein a distal end of the rotating shaft is positioned inside the recess, the rotating part being configured to rotate inside an aperture within the position sensing part in connection with the rotation of the cam, and wherein the position sensing part is configured to sense information regarding the rotation of the rotating part to determine a position of the height adjusting part.
