Our Cleaning Methods Air Cell Extraction™ technology uses thousands of tiny Air Cells which are 90% air and only 10% moisture, which prevents overwetting. Air Cell technology dramatically lowers moisture which eliminates problems associated with wet cleaning. The Von Schrader system applies dirt emulsifying cleaning bubbles (not gallons of water), brushes it all way down to the base of the carpet fiber using cylindrical brushes (unlike rotary brushes which merely clean the surface), and then floats the dirty bubbles before they can sink back down into the carpet or fiber. This simultaneous operation combined with air cell bubbles ensures that there's no danger of shrinkage, dry-rot, browning or mildew. Plus, the carpet is dry often in less than just one hour because we control the moisture.
