Change from interim to deep cleaning process at the turn of a switch—no mechanical changeover needed. Floating dual counter-rotating brushes agitate and permeate the cleaners into both sides of the carpet nap for even, thorough cleaning and improved carpet appearance. No operator adjustment needed. With the interim method using the iCapsol encapsulating chemical, the carpet is dry and ready for traffic in approximately 20 minutes. iCapsol interim cleaning process extends the time before re-soiling occurs and reduces wicking. The DUO machines provide exceptional maneuverability and visibility; their compact design makes it easy to operate in small areas. Dual floating vac shoes with glides provide consistent contact even over uneven surfaces for unmatched cleaning with no operator adjustment needed.
