Vacuum cleaner

A cleaner comprising:

• a suction port configured to guide air into a dust bin;
• a first cyclone part configured to separate dust from air sucked through the suction port;
• and
• a second cyclone part configured to separate dust from air discharged from the first cyclone part,
• wherein the second cyclone part comprises,
• a plurality of cyclone bodies each forming an outer wall around a hollow portion;
• a vortex finder having at least portion disposed on the inner side of each cyclone body;
• and
• a band member disposed to surround an outer surface of each vortex finder and configured to form a guide path to guide air discharged from the first cyclone part to the inner side of each cyclone body, and
• the cross-sectional area of the guide path increases from the center of the band member toward the outside of the band member.

A cleaner comprising:

• a suction port configured to guide air into a dust bin;
• a first cyclone part configured to separate dust from air sucked in through the suction port;
• and
• a second cyclone part configured to separate dust from air discharged from the first cyclone part,
• wherein the second cyclone part comprises,
• a plurality of cyclone bodies each having an inlet configured to receive air discharged from the first cyclone part;
• a vortex finder having at least a portion disposed on the inside of each cyclone body;
• a band member disposed to surround an outer surface of each vortex finder and configured to guide air discharged from the first cyclone part to the inside of each cyclone body;
• and
• a frame member formed to surround the band member and configured to guide air discharged from the first cyclone part together with the band member to the inside of each cyclone body, and
• the gap between the frame member and each inlet increases from the inside to the outside of the frame member.
