Abstract
A mobile floor cleaning machine has a clean water system with a reservoir for applying water to a floor during cleaning. The floor cleaning machine includes an ozone source which generates ozone in liquid form and introduces the liquid ozone directly into the circulating water for eliminating pathogens in the circulating water. The ozone is generated continuously and essentially instantaneously by the ozone source and destroys most bacteria, virus, fungus and mold in the circulating water at room temperature, while decaying harmlessly to oxygen within the water and producing fewer by-products than chemical sanitizers and having essentially no environmental impact.
Claims9
A floor cleaning machine comprising:
- a spray nozzle located at a forward portion of the floor cleaning machine or thereabouts;
- a liquid cleaning solution reservoir;
- a floor scrubbing assembly including a scrub member disposed aft of said vacuum nozzle and including a contact portion adapted to contact the surface of a floor to be cleaned;
- a motor coupled to said scrub member for moving said scrub member into contact against said floor for scrubbing said floor;
- a fluid conveying system coupled to said liquid cleaning solution reservoir and to said scrub member for providing cleaning solution to said scrub member;
- and
- an ozone cell coupled to said fluid conveying system for injecting liquid ozone into the liquid cleaning solution for eliminating pathogens in the cleaning solution.
