The present disclosure relates to a vacuum cleaner comprising an electric motor 3 and a blower producing an air flow through the vacuum cleaner. The electric motor and the blower are placed on a common vertical axis 17. A separator unit 13 is placed laterally with respect to the common axis of the motor and the blower. A bent conduit 19 connects the blower with the separator unit, and one end 21 of the conduit encloses the common vertical axis. The conduit comprises a portion located along the common axis 17 having a double wall forming a closed air pocket 23. This provides damping of noise emitted by the blower/motor and which propagates in the opposite direction of the air flow. |
