ABSTRACT:
A continuous flow recycling cleaning system includes a canister containing a liquid cleaning solution, and a dispensing conduit for conveying the cleaning solution from the canister to a cleaning tool head for direct application to a carpet, upholstery fabric or other material at an application area. A recovery conduit is connected to the cleaning tool head for returning recovered cleaning solution, along with air and extracted soil, to the canister. The system includes at least one ozone injector selectively positioned along a fluid flow pathway that includes the canister, the dispensing and recovery conduits, and the cleaning tool head. The fluid flow pathway further can include a counterflow conduit and an ozone-introduction conduit provided solely for the injection of ozone. Each injector is coupled to an ozone generator, to combine the ozone with the cleaning solution flowing through the injector. A portion of the ozone is dissolved in the liquid cleaning solution for cleaning, sanitizing and deodorizing the application area and interior surfaces along the fluid flow pathway. A surfactant is incorporated into the cleaning solution to improve the retention of dissolved ozone. A portion of the ozone remaining in the gaseous state sanitizes and deodorizes air within the system. The system includes an air exhaust, which can incorporate a filter for reducing ozone concentrations in the expelled air.
