Abstract
The present disclosure relates to a vacuum cleaner comprising an electric motorand a blower producing an air flow through the vacuum cleaner. The electric motor and the blower are placed on a common vertical axis. A separator unitis placed laterally with respect to the common axis of the motor and the blower. A bent conduitconnects the blower with the separator unit, and one endof the conduit encloses the common vertical axis. The conduit comprises a portion located along the common axishaving a double wall forming a closed air pocket. This provides damping of noise emitted by the blower/motor and which propagates in the opposite direction of the air flow.
