Abstract: A cyclone dust-separating unit is provided that includes a whirling current generating unit to rotate air drawn in through a suction nozzle, and a dust collecting bin having opened and closed ends to collect and store dust separated by a whirling current. The generating unit and the bin are separate tube members, and the generating unit includes a cyclone body having a first end with an air inlet and a second end with an air outlet, a spiral guide member on the first end to guide air flowed in through the air inlet in a spiral shape, an outflow pipe on the second end to extend to the outside of the cyclone body while penetrating through the air outlet, and a dust guide to connect a dust discharging opening with the opened end and to guide dust or dirt discharged through the dust discharging opening, to the opened end.

Abstract: A vacuum cleaner for use in either a canister form or a stick form is disclosed. The vacuum cleaner includes a cleaner body, a suction unit having an air suction opening formed in a bottom surface of the cleaner body to drawn in air, a dust collecting unit disposed in the cleaner body to separate dust or dirt from the air and to collect and store the dust or dirt therein, and a mode selecting unit on the cleaner body to select one of a first mode and a second mode. The first mode is a mode where a handle member for moving the cleaner body is connected to the cleaner body and the suction unit and the dust collecting unit are communicated with each other. The second mode is a mode where an external accessory is connected to the cleaner body to communicate with the dust collecting unit.
