Abstract

A floor cleaning device for automatically cleaning in front of and around lavatory appliances like urinals, toilets, sinks, and hand drying devices, wherein the floor cleaning device has a fixed unit, a mobile unit, and an extension mechanism connected to the fixed unit and the mobile unit that sprays disinfectant solution and recovers or removes waste solution during the extension or retraction of the mobile unit from and to the fixed unit.

Claims

1. An automatic floor cleaner comprising a cleaning and recovery unit wherein the cleaning and recovery unit comprises a fixed unit, a mobile unit, and an extension mechanism connected to the fixed unit and the mobile unit to permit the extension and retraction of the mobile unit from and to the fixed unit, wherein the fixed unit comprises a controller, a sensor, a motor, a power source, a disinfectant solution tank, a vacuum, and a recovery tank.

2. The automatic floor cleaner of claim 1, wherein the controller and the sensor control the activation of the motor for the extension or retraction of the mobile unit.

3. The automatic floor cleaner of claim 1, wherein the power source is AC or DC.

4. The automatic floor cleaner of claim 1, wherein the sensor is mounted on the exterior of the cleaning and recovery unit with a line of view in the direction of a target area of floor.

5. The automatic floor cleaner of claim 1, wherein the sensor is mounted on a urinal, toilet, sink, or hand drying device.

6. The automatic floor cleaner of claim 1, wherein the disinfectant solution tank is connected by tubing to the mobile unit for spraying disinfectant solution onto a target area of floor upon extension of the mobile unit from the fixed unit.

7. The automatic floor cleaner of claim 6, wherein the timing of spraying disinfectant solution is controlled by the controller.

8. The automatic floor cleaner of claim 1, wherein the vacuum further comprises its own collection tank, fan, motor, and exhaust port.

9. The automatic floor cleaner of claim 8, wherein the vacuum is connected by tubing to the mobile unit for recovery of urine and disinfectant solution from the target area of floor upon retraction of the mobile unit to the fixed unit.

10. The automatic floor cleaner of claim 8, wherein timing of the vacuum is controlled by the controller.

11. The automatic floor cleaner of claim 8, wherein the vacuum collection tank is connected by tubing to the recovery tank.

12. The automatic floor cleaner of claim 11, wherein an intake port of the vacuum is connected by tubing to the fixed unit in proximity of the mobile unit for the recovery of urine and disinfectant solution from a target area of floor upon retraction of the mobile unit to the fixed unit.

13. The automatic floor cleaner of claim 1, wherein the recovery tank is connected to an external drain or replaced by tubing connected directly to the external drain.

14. An automatic floor cleaner comprising a cleaning and recovery unit wherein the cleaning and recovery unit comprises a fixed unit, a mobile unit, and an extension mechanism connected to the fixed unit and the mobile unit to permit the extension and retraction of the mobile unit from and to the fixed unit, wherein the fixed unit is housed within a urinal, toilet, sink, or hand drying device.

15. The automatic floor cleaner of claim 14, wherein the fixed unit is a cartridge insertable into and removable from a cavity in the urinal, toilet, sink, or hand drying device.

16. An automatic floor cleaner comprising a cleaning and recovery unit wherein the cleaning and recovery unit comprises a fixed unit, a mobile unit, and an extension mechanism connected to the fixed unit and the mobile unit to permit the extension and retraction of the mobile unit from and to the fixed unit, wherein the mobile unit further comprises a spray port for spraying disinfectant solution onto a target area of floor, a recovery port for suctioning solution from the target area, and a scrapping implement for contacting the target area and collecting solution from the target area upon retraction of the mobile unit to the fixed unit.

17. The automatic floor cleaner of claim 16, wherein the scrapping implement is a squeegee.

18. An automatic floor cleaner comprising a cleaning and recovery unit wherein the cleaning and recovery unit comprises a fixed unit, a mobile unit, and an extension mechanism connected to the fixed unit and the mobile unit to permit the extension and retraction of the mobile unit from and to the fixed unit, wherein the extension mechanism first lifts and then extends the mobile unit, and wherein the retraction mechanism first drops and then retracts the mobile unit.

19. A method of automatically cleaning a floor surface using a cleaning and recovery unit, comprising the steps of (a) activating a sensor, (b) extending a mobile unit, (c) spraying disinfectant solution onto a target area of floor during extension of the mobile unit, (d) contacting the mobile unit with the floor, and (e) retracting the mobile unit over the target area.

20. The method of claim 19, wherein the step of retracting the mobile unit further comprises the steps of scraping and suctioning.

21. The method of claim 19, wherein the step (a) is replaced by activating on a timed basis.

22. The method of claim 19, wherein the step (c) is replaced by spraying disinfectant solution onto a target area of floor during retraction of the mobile unit.

23. An automatic floor cleaner comprising a cleaning unit, wherein the cleaning unit comprises a fixed unit, a mobile unit, and an extension mechanism connected to the fixed unit and the mobile unit to permit the extension and retraction of the mobile unit from and to the fixed unit, wherein the fixed unit comprises a controller, a sensor, a motor, a power source, and a disinfectant solution tank, and further wherein the disinfectant solution tank is connected by tubing to the mobile unit for spraying disinfectant solution onto a target area of floor upon extension of the mobile unit from the fixed unit.

24. A method of automatically cleaning a floor surface using the cleaning unit of claim 23, comprising the steps of (a) activating the sensor, (b) extending the mobile unit, (c) spraying disinfectant solution onto the target area of floor during extension of the mobile unit, and (d) retracting the mobile unit.

25. The method of claim 23, wherein the mobile unit is extended on a timed delay at predetermined time periods after the sensor is activated.
