IN USING EITHER OF SAIS DEVICES A LIQUID DETERGENT IN PREDETERMINED QUANTITIES IS APPLIED TO THE CARPET, AND THE MOPHEAD IS 000000000000000MECHANICALLY MOVED OVER THE WETTED AREA TO SHAMPOO PILE. THE RESILIENT NYLON FIBES SUSTAIN THE WEIGHT OF THE DEVICE AND PROVIDE AN AGGRESSIVE SCRUBBING ACTION HELPING TO RELEASE THE SOIL FROM THE FIBERS. THE SBSORBENT CELLULOSIC YARNS IN THE MOP SOAK UP THE SOILED LIQUID DETERGENT.
