Claims
- 1. A pressure washer comprising:
a first container adapted to contain a first liquid therein; a second container adapted to contain a second liquid therein; a valve; a first conduit fluidly connecting the first container to the valve; a second conduit fluidly connecting the second container to the valve; a single engine-powered pump adapted to receive water from a water source; a mixing device adapted to receive water from the pump and adapted to mix at least one of first liquid and the second liquid received from the valve with the water received from the pump.
- 2. The pressure washer of claim 1, further comprising:
a single device conduit fluidly connected between the valve and the mixing device, the valve being adjustable to selectively place one of the first and second containers in fluid flow communication with the mixing device through the device conduit.
- 3. The pressure washer of claim 2, further comprising:
a third container adapted to contain water; and a third conduit fluidly connecting the third container to the valve, the mixing valve adapted to mix at least one of the first liquid, the second liquid, and the water from the third container received from the valve with the water received from the pump such that the valve can be adjusted to flush out the valve and device conduit with the water from the third container.
- 4. The pressure washer of claim 1, wherein the water from the water source is supplied to the pump through a garden hose.
- 5. The pressure washer of claim 1, wherein the first and second liquids are chemical products.
- 6. The pressure washer of claim 5, wherein the chemical product of the first container is one of a detergent product, a car wash product, a deck wash product, an automobile wax product, and a multipurpose cleaning product, and the chemical product of the second container is a different one of a detergent product, a car wash product, a deck wash product, an automobile wax product, and a multipurpose cleaning product.
- 7. The pressure washer of claim 1, wherein the mixing device is a venturi-type eductor mixer.
- 8. The pressure washer of claim 1, further comprising a chassis, wherein the pump, valve, and containers are supported by the chassis.
- 9. The pressure washer of claim 1, wherein the valve includes a valve body that is connected to the first and second conduits and a distributor that is connected to the device conduit and mounted for movement relative to the valve body.
- 10. The pressure washer of claim 9, wherein the distributor includes a channel for selectively fluidly connecting one of the first and second containers to the mixing device.
- 11. The pressure washer of claim 9, wherein the valve includes a position retention mechanism between the distributor and the valve body to maintain the distributor at a selected position.
- 12. The pressure washer of claim 9, further comprising a control console including a product selector device, wherein the product selector device is coupled to the control console and the distributor and adjusts the valve.
- 13. The pressure washer of claim 12, wherein the product selector device is a manually adjusted rotary knob.
- 14. The pressure washer of claim 12, wherein the pressure selector device is a manually linearly-actuated lever.
- 15. The pressure washer of claim 1, further comprising an internal combustion engine driving the engine-powered pump, the engine including a throttle, the pressure washer further comprising a control console including a pressure selector device, wherein the pressure selector device is coupled to the control console and the throttle of the engine and adjusts the speed of the engine and the pump.
- 16. The pressure washer of claim 1, further comprising a spray wand fluidly connected to the mixing device.
- 17. A method for operating a pressure washer comprising:
driving a single pump with an engine; pumping water from a water source with the pump through a mixing device; positioning a valve to direct a first liquid from a first container, through a first conduit and the valve, and to the mixing device; mixing the first liquid with the water within the mixing device; positioning the valve to direct a second liquid from a second container, through a second conduit and the valve, and to the mixing device; and mixing the second liquid with the water within the mixing device.
- 18. The method of claim 17, further comprising:
positioning the valve to direct water from a third container, through a third conduit and the valve, and to the mixing device; and mixing the water from the third container with the water from the water source within the mixing device.
- 19. The method of claim 17, further comprising mixing within the mixing device one of the first liquid, the second liquid, and the water from the third container with water from a water source.
- 20. The method of claim 17, further comprising:
connecting a garden hose between the water source and the pump, wherein pumping water from a water source includes pumping water from the water source through the garden hose.
