1. A cleaning device for cleaning a porous membrane that comprises a first layer comprising carpet fibers, a second layer comprising a carpet backing, and a third layer comprising a padding, wherein the cleaning device comprises:
an extraction device comprising a nozzle, wherein the nozzle comprises a substantially flat bottom surface configured to be disposed on top of the porous membrane, and wherein the extraction device provides suction to the porous membrane; and
a sub-surface fluid injector comprising:
a tube in fluid communication with a fluid reservoir containing a cleaning fluid;
a tip disposed at an end of the tube for inserting the sub-surface fluid injector beneath the porous membrane;
a hole formed in a surface of the tube; and
a pulsating fluid valve that pulsates the cleaning fluid through the tube such that the cleaning fluid flows through the tube and out of the hole;
wherein at least a portion of the tube is configured to be placed beneath each of the first layer, the second layer, and the third layer of the porous membrane;
wherein the pulsating fluid valve when actuated causes the cleaning fluid to flow through the tube and out of the hole such that the cleaning fluid physically agitates the porous membrane when the cleaning fluid is discharged from the tube under pressure;
wherein the tip of the sub-surface fluid injector is configured to be disposed underneath the nozzle of the extraction device such that the extraction device provides the suction to extract the cleaning fluid through each of the first layer, the second layer, and the third layer of the porous membrane.
