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.

Vacuum cleaner

A vacuum cleaner having a vacuum source adapted to generate an airstream, a filter, a separating unit having a first sub-separator and a second sub-separator, and airflow passages to connect the vacuum source, the filter and the separating unit in a first configuration corresponding to a vacuum cleaning mode and a second configuration corresponding to a filter cleaning mode. In the vacuum cleaning mode, the airflow passages are configured to direct the airstream through the separating unit such that the airflow passes in parallel through the first sub-separator and the second sub-separator, then in a forward direction through the filter. In the filter cleaning mode, the airflow passages are configured to direct the airstream through the separating unit such that airflow passes in a reverse direction through the filter, and then through the separating unit such that the airflow passes in series through the first sub-separator and the second sub-separator.
