摘要： A vacuum cleaner comprising an electric motor, an impeller and an axial diffuser arranged on a common axis is provided. The impeller is connected to the electric motor and is arranged for rotation on the common axis to achieve a radial air flow. The radial air flow is redirected into an axial air flow. The diffuser passages are arranged between an inner circumferential wall and an outer circumferential wall, wherein the walls are coaxially arranged around the common axis. Each diffuser passage is delimited in a circumferential direction between the walls by vanes extending between the inner wall and the outer wall and in an axial direction extending substantially in parallel with the common axis. The vanes are arranged in at least two rows being consecutively arranged in the axial direction extending substantially in parallel with the common axis.
