Floor scrubber
First Claim
1. A floor scrubber for cleaning floor surfaces as an incident to movement over the floor surface comprising:
- a cleaning head having a housing defining a downwardly opening cleaning zone, at least one spray nozzle supported within said cleaning zone, said cleaning head having a liquid inlet connectable to a pressurized liquid supply for directing cleaning fluid to said at least one nozzle for direction onto and cleaning of a floor surface over which the cleaning head is positioned, said housing further defining having a downwardly opening vacuum zone, said vacuum zone having a vacuum pressure inlet connectable to a vacuum pressure source for creating a vacuum within said vacuum zone for removing liquid directed onto the floor from said at least one spray nozzle during a cleaning operation.

Abstract
A floor scrubber for cleaning floor surfaces that includes a cleaning head which defines a downwardly opening cleaning zone having a plurality of spray nozzles connected to a power washer pump for directing pressurized liquid flow streams onto the floor surface during a cleaning operation. The cleaning head further defines a separate downwardly opening vacuum zone connected to a wet/dry vacuum device operable for creating a vacuum pressure within the vacuum zone for removing liquid that has been directed onto the floor surface. The wet/dry vacuum device preferably further is operable for selectively directing a positive air flow into the vacuum zone to facilitate drying of the floor surface after cleaning and vacuum removal of the liquid.

18. A floor scrubber for cleaning floor surfaces as an incident to movement over the floor surface comprising:
a cleaning head having a housing defining a downwardly opening cleaning zone, a spray nozzle assembly mounted within an underside of said housing including a plurality of spray nozzles for directing pressurized liquid flow streams onto the floor during a cleaning operation, said housing having a liquid inlet for directing pressurized liquid from a pressurized liquid supply to said spray nozzle assembly and the spray nozzles mounted thereon, said spray nozzles including at least one turbo nozzle having a turbulence creating internal agitation member for agitating the flow stream prior to impingement on the floor surface for loosening dirt and grime on the floor surface, and at least two of said nozzles being fan spray nozzles for directing fan spray patterns onto the floor surface for moving dirt and grime removed from the floor surface along with the cleaning head as an incident to movement over the floor surface. - View Dependent Claims (19)

20. A floor scrubber for cleaning floor surfaces as an incident to movement over the floor surface comprising:
a cleaning head having a housing defining a downwardly opening cleaning zone, a nozzle assembly supported within said cleaning zone, said cleaning head having a liquid inlet connectable to a pressurized liquid supply for directing cleaning fluid to said spray nozzle assembly for direction onto and cleaning of a floor surface over which the scrubbing head is positioned, and said housing having a chemical inlet separate from said liquid inlet connectable to a chemical supply for directing a chemical into said cleaning zone and onto said floor surface during a cleaning operation.

21. A floor scrubber for cleaning floor surfaces as an incident to movement over the floor surface comprising:
a cleaning head having a housing defining a downwardly opening cleaning zone, a spray nozzle assembly supported within said cleaning zone, said cleaning head having a liquid inlet connectable to a pressurized liquid supply for directing cleaning fluid to said spray nozzle assembly for direction onto and cleaning of a floor surface over which the scrubbing head is positioned, and a plurality of roller balls for supporting a lower perimeter of said housing in predetermined spaced relation over a floor surface to be cleaned during movement of the cleaning head over the floor surface during a cleaning operation.
- 22. A method of using a floor scrubber having a cleaning head having a downwardly opening cleaning chamber within which a spray nozzle assembly is supported and a downwardly opening vacuum chamber, comprising the steps of directing a pressurized liquid to the spray nozzle assembly for direction onto a floor surface over which the scrubber is moved for cleaning the floor surface during a cleaning operation, and communicating a vacuum pressure to said vacuum chamber to remove liquid that has been directed onto the floor surface during a cleaning operation.
