ABSTRACT:
A floor washing apparatus for removing oil, grease and other residue contaminants from a floor surface includes a housing supported on wheels and a spray suction head removably attachable to the housing so that a suction intake mouth is maintained in close spaced relation above the floor surface as the apparatus as moved on the floor. A wash tank within the housing holds a predetermined charge of wash solution and includes a pump therein to discharge a forced flow of the cleaning solution through one or more nozzles in the spray suction head and onto the floor surface, and a vacuum suction motor for creating a negative pressure within the wash tank to draw the wash solution and contaminant residues removed from the floor surface through the suction intake mouth and an interconnecting flexible hose for return to the wash tank. During a recycling process, a valve assembly releases contaminated wash solution from the wash tank into a distillation chamber where the wash solution is heated to produce vapors. A condenser cools the vapors to a liquid state, yielding non-contaminated, pure wash solution which is directed into a holding tank for subsequent transfer and use in the wash tank.
