Abstract: Disclosed herein is a cleaner having an improved structure configured to improve the cleaning performance. The cleaner comprises a suction unit provided inside a body. The suction unit includes an impeller configured to suction air by rotating about a shaft, and a diffuser configured to guide air discharged from the impeller. The impeller includes a hub, and a blade disposed on the hub, and provided with a leading edge disposed in an upstream side in a direction in which air introduced into the suction unit flows, and a trailing edge disposed in a downstream side in the direction in which the air introduced into the suction unit flows. The leading edge of the blade forms an inclination of 60 degrees or more and 80 degrees or less with respect to an axial direction.
