摘要

Disclosed are a cyclone vessel dust collection and a vacuum cleaner including the same. The cyclone vessel dust collector comprises a cyclone vessel main-body including a primary cyclone vessel unit for separating dusts from dust containing air, and one or more secondary cyclone vessel units for separating dusts from the air passing through the primary cyclone vessel unit, the secondary cyclone vessel units being arranged to surround at least a part of the primary cyclone vessel unit; and a dirt collection bin for receiving dusts or the like separated by the cyclone vessel main-body, wherein the cyclone vessel main-body has an outer circumference with a non-constant radius. Therefore, the cyclone vessel dust collector can have a dust collection capability of large capacity with a small size.
