1. A multi-cyclone dust separating apparatus comprising:
a cyclone body including a main cyclone, and a plurality of cyclone cones communicating with the main cyclone and arranged around a lower part of the main cyclone, each of the plurality of cyclone cones being formed in a reverse conical shape having a diameter that is reduced as approaching a top end thereof;
a top cover fitted on a top of the cyclone body and having an air inflow port for introducing ambient air into the main cyclone; and
a discharge cover fitted on a bottom of the main cyclone so as to collect and discharge the air discharged from the plurality of cyclone cones,
wherein most of the air introduced into the top of the main cyclone through the air inflow port is discharged to the bottom of the main cyclone without direction to ascend, thereby being introduced into the plurality of cyclone cones through a bottom end thereof.
