Abstract

A modular power washer contains a power washing system ( 10 ), containing a base unit ( 20 ) and an accessory unit ( 34 ), wherein the accessory unit ( 34 ) is removably-attached to the base unit ( 20 ). The base unit ( 20 ), contains a housing ( 22 ), a pump ( 26 ), a motor ( 24 ), a power source ( 28 ), an input valve ( 64 ), and an output valve ( 32 ). The housing ( 22 ), contains the pump ( 26 ), and the motor ( 24 ), therein, and the housing ( 22 ), at least partially contains the power source ( 28 ), therein. The motor ( 24 ), is operatively-connected to the power source ( 28 ). The pump ( 26 ), is operatively-connected to the motor ( 24 ). The pump ( 26 ), is fluidly-connected to the input valve ( 64 ), and the output valve ( 32 ). The accessory unit ( 34 ), is selected from a hose storage unit ( 68 ), an additive tank ( 88 ), a handle ( 36 ) a roll bar ( 50 ), a frame ( 72 ), a wheel ( 74 ), and a combination thereof. A kit and a method of use are also described herein.

First claim

The invention claimed is:

1. A modular pressure washing system comprising:
a base unit comprising a housing, a pump, a motor, a power source, an input valve, and an output valve, wherein the housing contains the pump and the motor, wherein the housing at least partially contains the power source, wherein the motor is operatively-connected to the power source, wherein the pump is operatively-connected to the motor, wherein the pump is fluidly connected to the input valve, and wherein the pump is fluidly-connected to the output valve; and
a frame comprising:
a plurality of wheels including a first wheel and a second wheel,
a cut-out area disposed between the first and second wheels, and
a support plate disposed adjacent to the cut-out area and configured to support the housing of the base unit,
wherein the frame is removably-attachable to the base unit such that the input valve is received in the cut-out area when the base unit is attached to the frame.

2. The modular pressure washing system according to claim 1 , comprising a telescoping handle extending from the frame.

3. The modular pressure washing system according to claim 1 , wherein the frame comprises one or more receiving slots, wherein the base unit comprises one or more attachment sites projecting from the housing, and wherein the one or more attachment sites of the base unit are each configured to engage with one of the one or more receiving slots of the frame when unit is attached to the frame.

4. The modular pressure washing system according to claim 1 , wherein the power source is selected from the group consisting of an internal combustion engine, a DC power source, an AC power source and a combination thereof.

5. The modular pressure washing system according to claim 4 , wherein the power source comprises a DC power source.

6. The modular pressure washing system according to claim 5 , wherein the DC power source is a battery.

7. The modular pressure washing system according to claim 6 , wherein the housing further comprises a top portion and wherein the battery is located within the top portion.

8. The modular pressure washing system according to claim 6 , wherein the housing further comprises a battery seal and wherein the battery seal prevents water from accessing the battery.

9. The modular pressure washing system according to claim 4 , wherein the power source comprises an AC power source.

10. The modular pressure washing system according to claim 4 , wherein the power source comprises an DC power source and an AC power source.

11. The modular power washing system according to claim 1 , further comprising a hose engaged with the input valve and extend through the cut-out area of the frame.

12. The modular power washing system according to Claim 11 , wherein the frame is configured to be attached to the base unit and removed from the base unit without disengaging the hose from the input valve.

13. The modular pressure washing system according to claim 1 , further comprising a handle coupled to the frame, wherein the handle is selected from a telescoping handle and a non-telescoping handle.

14. The modular pressure washing system according to claim 1 , wherein the base unit comprises rear feet, and wherein the rear feet are configured to be disposed between the housing of the base unit and the support plate of the frame when the base unit is attached to the frame.
