Higher temperatures – more intense cleaning that removes dirt and debris and breaks down any residues in the carpet fibers. More power – allows the steam and hot water to penetrate on a deeper level, as well as any other cleaning solutions. Greater suction – removes all liquids and residue left over in your carpets after the cleaning process. Faster and more thorough cleaning – less need to go over sections of the carpet multiple times, decreasing risk of damage and wear from the cleaning process.
