Patent ID: 8312746

Claim:
A stain-removing machine, comprising: two tubes which are joined and communicated to one another at one of the ends thereof, an area of fabric to be cleaned being clamped between them, so that a fluid can flow from one to the other; wherein the joining between the tubes comprises a closure and adjustment mechanism, which can hold up the fabric; wherein at least one of said tubes has a fill and/or discharge opening or valve for supplying or releasing the fluid directly from the outside or from another container; and perforated elastic membranes or screens securing said fabric, at the ends of each tube, such that they are on both sides of the fabric, said membranes or screens being arranged for gently rubbing the fabric due to shifting caused by pressure or negative pressure of the fluid, wherein the stain-removing machine comprises at least one of the features of: (i) one of the tubes of the machine being incorporated in one part of a stain-removing table on a screen therein, to which spray guns for spraying cleaning products are coupled by leak-tight adaptors, and the other tube being incorporated in an opposite part of the table and arranged for coupling to a waste suction device, and (ii) comprising a suction source coupled at the distal end of one of the tubes to provide propulsion to the fluid in operation of the machine, and a propulsion source coupled to the distal end of the other tube to provide propulsion to the fluid in operation of the machine, the direction thereof being able to be varied, as desired, depending on if the suction source and the propulsion source are coupled at one end of the stain-removing machine or the other end of the stain-removing machine.
