Abstract: An upright vacuum cleaner includes a suction nozzle unit, an inlet formed on a bottom surface of the suction nozzle unit, an injection path disposed near the inlet, a suction motor mounted in the suction nozzle unit, and a main body attached to the suction nozzle unit and in fluid communication with the suction motor. The injection path ejects air toward a surface to be cleaned. The suction motor generates a suction force to draw in air and dust through the inlet. The main body separates dust from the air using centrifugal force, collects the dust, and discharges the air to the suction nozzle unit. The air discharged from the main body flows through the suction motor, is ejected from the injection path toward the surface to be cleaned, and is then suctioned into the inlet so that a portion of the discharged air circulates within the vacuum cleaner.

Abstract: A power recharger for use with a robot cleaner has a recharging terminal to which a battery terminal of the robot cleaner is docked and an anchor member on a rear side of the body of the recharging unit. The anchor member fills in the space defined between the wall of the room and the power recharger. The anchor member therefore securely supports the power recharger in the battery recharging process.

Abstract: 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.
