SMART® (Soil Mobilization And Removal Technology ) is a process unique to SMART® Carpet that uses the power of static attraction to remove soil and residues while leaving your carpets virtually moisture free! Using a proprietary formula exclusive to SMART®, charge differential, or the natural occurrence of positive and negative charge in nature, is used to transfer soil from carpet fiber to static-attraction pads. This process is powerful and can fully saturate a pad in less than a minute. Each van contains over 100 of these pads and saturated pads are washed in Dextor extraction machines and re-usable for next day service. This carpet cleaning process is Gold Certified Deep Cleaning by the Carpet & Rug Institute.
