It's The Von Schrader LMX Low Moisture Foam Extraction System™

• Uses dry foam - not gallons of water!
• Cylindrical brush cleans down to the base of the carpet (unlike rotary brushes which merely cleans the surface!)
• Vacuums immediately - powerful suction lifts out dirt laden foam in seconds.

Only the Von Schrader LMX Carpet Extraction System™ applies a dirt-emulsifying low moisture foam, brushes it thoroughly into the carpet and removes both foam and dirt immediately before it can sink back down into the carpet. Only the Von Schrader LMX Carpet Extraction System™ has this patented feature. Because only foam is used, your carpet is ready for use in an hour or so. There is no danger of shrinkage, dry-rot, browning or mildew.

Remember; steam is just a lot of hot water, "rotary brushes" just take dirt for a joy ride, and bonnet methods only superficially clean the surface. Only the LMX cleans deeply with a low moisture foam and then removes dirt and foam immediately.
