Abstract
An improved carpet cleaning machine convertible for brush-aided cleaning or vacuuming includes a pair of powered brushes counter-revolving for stroking solvent-dampened carpet cleaning particles through the carpet and along carpet fibers during initial cleaning. A separately-powered pod is detachable from the machine during brush-aided carpet cleaning and attached to a machine-mounted vacuum nozzle for carpet vacuuming to pick up the dirt-laden particles. The pod has first and second media selected to remove particles of differing sizes from air flowing through the pod. During initial carpet cleaning when vacuum is not needed, the pod may be detached and used in another area for hand-vacuuming carpeted stairs and other "small-area" places.
