  • Patent number: 6381801
    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.
