摘要: The present disclosure relates to a vacuum cleaner comprising an electric motor (3) and a blower (5), producing an air flow (9) through the vacuum cleaner. The electric motor and the blower are placed on a common vertical axis (17). A separator unit (13) is placed lateral 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. In the prolongation of the common axis the conduit comprises a portion with 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.
