ABSTRACT:
A self-propelled brushless surface cleaner with reclamation is provided as a self-contained vehicle. A cleaning head mounted to the vehicle extends forward therefrom. The cleaning head has a deck and a skirt extending from the deck such that when the skirt is placed in contact with the surface to be cleaned, a cleaning volume is defined. The cleaning head has at least one vent port formed in a forward portion thereof and at least one vacuum port formed in a rear portion thereof. Nozzles are mounted in the cleaning volume for movement therein when liquid under pressure is supplied thereto and sprayed therefrom. A liquid supply system supplies the liquid under pressure to the nozzles so that the surface to be cleaned is effectively scrubbed by the liquid to produce a mixture of the liquid and contaminants loosened from the surface to be cleaned. A vacuum recycling system coupled to the vacuum port(s) draws high-pressure air through the vent port(s) and over the surface being sprayed with the liquid under pressure. The mixture of liquid and contaminants is suctioned through the rear vacuum port(s) and filtered to separate the liquid from the contaminants. The liquid so-separated is returned to the liquid supply system for reuse thereby.
