ABSTRACT:
A system and method for cleaning and drying porous fabrics such as tufted carpet are disclosed. A porous fabric is first wetted and then passed over a slotted vacuum pipe. A backup plate is positioned opposite the slot, and the fabric passes between the slot and plate. Air is forced to flow in an indirect route into the slot to maximize cleaning and drying. The gap between the slot and backup plate is adjustable to enable the system to handle fabrics or carpets of varying thickness.
