ABSTRACT:
An improved rotary brush carpet cleaning apparatus provides superior cleaning performance both by more efficiently dispensing shampoo onto a scrubbed portion of a carpet and by more effectively holding an extraction ring against the surface being cleaned and thereby better extracting dirt and used shampoo. The apparatus includes an arrangement of two springs (instead of the one spring used in the prior art) biasing the extraction ring downward from a chassis onto the carpet being scrubbed. The improved apparatus also minimizes operator fatigue by: a) reducing the overall weight of the cleaning machine; b) supporting the weight of a shampoo feed tank with the spinning brush, rather than on the operator's arms: and c) providing an improved mechanical advantage for resisting torques and imbalances arising from the spinning brush in a way that does not also compromise the maneuverability of the machine.
