Patent attributes
The present invention is directed to a cleaning system (e.g., carpet cleaning system) that includes a collection tank (also referred to in the art as a waste tank, waste water tank, recovery tank, or the like) that at least generally tapers toward a bottom end of the same. Accordingly, at least one wall of the collection tank may be characterized as being at least generally sloped, angled, and/or slanted. This tapering of the collection tank may be oriented at least generally toward a release valve associated with the collection tank. In addition to the collection tank, the cleaning system may include a fluid supply tank that, at least in one embodiment, generally tapers toward a top end of the same. Moreover, the tapering of this fluid supply tank may be said to be oriented at least generally toward a filling port associated with the fluid supply tank.
