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

In a vacuum cleaner comprising a suction fan and a motor for driving the fan, a noise reduction wall construction is provided in front of and spaced from the inlet of the fan. The wall construction comprises two parallel, mutually spaced wall panels which by means of intermediate spacer means are firmly interconnected to form a rigid unit.
