A vacuum cleaner is provided to decrease the height of the vacuum cleaner and enhance cleaning efficiency by reducing flow resistance in a space wherein cyclone flow generates. A vacuum cleaner comprises a first cyclone part(110), a second cyclone part(120), and a first passage divider(131). The first cyclone part primarily separates debris by the first cyclone flow of suction air. The second cyclone part secondarily separates the debris by the second cyclones flow inside plural second cyclones of the suction air passed through the first cyclone part. The first passage divider seals a space from an inlet of the first cyclone part to outlets of each second cyclone, and also has an area having plural through-holes. The second cyclones, whose surface contacted to the first passage divider is horizontal, collect the debris from the center of the first cyclone part, and has the outlets and a dust discharging port inclined toward two ends in an axial direction. A vortex splitter has the outlets of the second horizontal cyclones to prevent vortex of air discharged through the outlets of the second horizontal cyclones.
