ABSTRACT OF THE DISCLOSURE A housing in a vacuum cleaner is subdivided into a first space and a separate second space which does not communicate with the first space but is in heat-exchanging relationship with the first space. An impeller is located in the second space for sucking dust-laden air into one end of the second space and dis- charging it out the other. The drive motor for the impeller means is located in the first space. Thus, the drive means is not contact- ed by the dust-laden air passing through the second space but is nevertheless cooled by such dust-laden air.
