Claims
- 1. A surface cleaning and material removal system for cleaning material from a surface, the system comprising:a housing having a base and at least one wall extending from the base defining a cavity between the wall and the base; a drive shaft extending through the housing into the cavity; a rotatable cleaning mechanism attached to the drive shaft and positioned within the cavity; an air motor for driving the drive shaft; and means for applying a vacuum flow to the cavity.
- 2. The system of claim 1, wherein the rotatable cleaning mechanism is a rotatable high pressure washing head having a plurality of fluid jets, and wherein the system further comprises an ultra high pressure fluid supply fluidly connected to the washing head.
- 3. The system of claim 2, wherein the drive shaft has a fluid passage providing fluid communication between the fluid supply and the washing head.
- 4. The system of claim 1, wherein the rotatable cleaning mechanism is a rotatable brush.
- 5. The system of claim 1, further comprising:a second drive shaft extending through the housing; and a second rotatable cleaning mechanism attached to the second drive shaft; the second rotatable cleaning mechanism positioned within the cavity.
- 6. The system of claim 5, wherein each of the drive shafts is driven by the air motor.
- 7. The system of claim 5, further comprising a second air motor driving the second drive shaft.
- 8. A surface cleaning and material removal system for cleaning material from a surface, the system comprising:a housing having a base and at least one wall extending from the base defining a cavity between the wall and the base; a drive shaft extending through the housing into the cavity; a supply of high pressure liquid; a rotatable cleaning mechanism attached to the drive shaft and positioned within the cavity; the cleaning mechanism operatively connected to the supply of high pressure liquid; a supply of pressurized air; an air motor for driving the drive shaft; the air motor operatively connected to the supply of pressurized air; means for applying a vacuum flow to the cavity; a first trigger controlling the delivery of the pressurized air from the supply of pressurized air to the air motor; and a second trigger controlling the delivery of liquid to the cleaning mechanism.
- 9. The system of claim 8, wherein the cavity has an outer perimeter; the system further comprising sealing means positioned along the outer perimeter of the cavity for at least partially sealing the cavity along the outer perimeter of the cavity.
- 10. The system of claim 9, wherein the sealing means includes a flexible member.
- 11. The system of claim 9, wherein the sealing means is a plurality of bristles.
- 12. The system of claim 8, wherein the second trigger is operatively connected to the first trigger.
- 13. The system of claim 12, further comprising a trigger connection hose extending between the first and second triggers.
- 14. The system of claim 8, wherein the first trigger locks and unlocks the second trigger.
- 15. The system of claim 8, further comprising first and second handles; the first trigger carried by the first handle; and the second trigger carried by the second handle.
- 16. A surface cleaning and material removal system for cleaning material from a surface, the system comprising:a housing having a base and at least one wall extending from the base defining a cavity between the wall and the base; the housing adapted to be held by a user with two hands; a first handle connected to the housing; a second handle connected to the housing; the first handle being spaced from the second handle; a drive shaft extending through the housing into the cavity; a supply of high pressure liquid; a rotatable cleaning mechanism attached to the drive shaft and positioned within the cavity; the cleaning mechanism operatively connected to the supply of high pressure liquid; means for applying a vacuum flow to the cavity; and a supply of pressurized air and an air motor for driving the drive shaft; the air motor operatively connected to the supply of pressurized air.
- 17. The system of claim 16, further comprising a first trigger controlling the delivery of the pressurized air from the supply of pressurized air to the air motor; and a second trigger controlling the delivery of liquid to the cleaning mechanism.
- 18. The system of claim 17, wherein the first trigger is carried by the first handle and the second trigger is carried by the second handle.
