The apparatus may include means for holding the mat flat on the incline, means for extracting water from the cleaned mat, and means for cleaning and reusing water.

Abstract: An ozone and/or hydroxyl laundry system that injects ozone and/or hydroxyls into the chemical injection system in order to allow the system to inject ozone and/or hydroxyls as other cleaning chemicals are injected into the washer. This allows ozone and/or hydroxyls to be injected through the wash cycle rather than just during the initial fill phase and avoids the expense and maintenance of adding ozone and/or hydroxyls recirculation plumping to an ozone and/or hydroxyls laundry system. Accordingly, ozone and/or hydroxyl levels may be maintained at superior levels throughout the wash cycle.
