1. A multi-functional floor-cleaning tool for use with a pressurized-liquid source and a vacuum source, comprising: a housing having a front wall, a back wall, a top wall connecting the front and back walls, an interior surface, a liquid-delivery opening, and a soil-uptake opening, the soil-uptake opening being connectable to a vacuum source; a first squeegee blade depending from the front wall; a second squeegee blade depending from the back wall; an interior space defined by the interior surface, first squeegee blade, and second squeegee blade; a diverter valve having at least an inlet, a first outlet, a second outlet, and a diverter, the diverter capable of selectively directing the flow of a liquid from the inlet to either the first outlet or the second outlet, the diverter valve being connectable to a pressurized-liquid source; a high-pressure nozzle connected to the first outlet of the diverter valve, the high-pressure nozzle constructed and arranged to deliver a liquid into the interior space via the liquid-delivery opening; and a low-pressure nozzle connected to the second outlet of the diverter valve, the low-pressure nozzle constructed and arranged to deliver a liquid exterior to the interior space. 2. The multi-functional floor-cleaning tool of claim 1 wherein the high-pressure nozzle has an oulet orifice, and the high-pressure nozzle is constructed to deliver a focused, pinpoint jet of liquid from the outlet orifice. 3. The multi-functional floor-deaning tool of claim 1 wherein the low-pressure nozzle is constructed and arranged to deliver a liquid downward from behind the back wall of the housing. 4. The multi-functional floor-cleaning tool of claim 3 wherein the low-pressure nozzle is a fan nozzle, whereby a liquid exiting the low-pressure nozzle has a fan-shaped patterm. 5. The multi-functional floor-cleaning tool of claim 1 wherein the low-pressure nozzle is a fan nozzle, whereby a liquid exiting the low-pressure nozzle has a fan-shaped pattern. 6. The multi-functional floor-cleaning tool of claim 5 wherein the low-pressure nozzle has an outlet orifice and an arcuate deflector plate spaced from the outlet orifice. 7. The multi-functional floor-cleaning tool of claim 1 wherein the diverter valve is a three-way valve, the diverter capable of selectively directing the flow of a liquid from the inlet to either the first outlet or the second outlet. 8. The multi-functional floor-cleaning tool of claim 7 wherein the diverter valve includes a handle operatively connected to the diverter, thereby enabling an operator to selectively direct the flow of a liquid from the inlet to either the first outlet or the second outlet. 9. The multi-functional floor-cleaning tool of claim 8 wherein the diverter of the diverter valve may be oriented in a plurality of positions so as to provide larger and smaller flow paths to the first outlet, larger and smaller flow paths to the second outlet, and a completely blocked flow path to both the first and second outlets. 10. The multi-functional floor-cleaning tool of claim 1 wherein each of the first and second squeegee blades has an exterior surface and a base surface, the exterior surface including serrations which extend from the base surface upward toward the housing. 11. The multi-functional floor-cleaning tool of claim 1 wherein the housing further includes at least two wheels or glides.
