spray extraction is still the unsurpassed carpet/upholstery cleaning system. In this process, cleaning solution is sprayed into the carpet under pressure and picked up again immediately. The dirt is rinsed from deep down out of the carpet pile and not just from the top third.
Carpets cleaned by spray extraction stay clean longer. With strong vacuum suction the maximum residual dampness is only 15-20%. The spray extraction process is gentle and easy on carpets.
