ABSTRACT:
A carpet cleaning machine includes a centrifugal separator with an air stream exit mouth having a mouth area. The improvement involves two air flow guides having, respectively, first and second apertures. The area of the second aperture is less than that of the first aperture and the guides define an annular cavity between them. Such cavity "captures" dirty material that would otherwise pass downstream into a mechanical filter and prematurely clog such filter. A new, related machine nozzle and method for removing dirty material from air flowing in a carpet cleaning machine are also disclosed.
