- 8. A water spray tool according to claim 1 wherein the valve is normally biased toward its first position.
- 9. A water spray tool according to claim 1 wherein the first, second and third nozzle portions are adapted to form a fluid stream flowing at a rate of at least about 6.6 gallons per minute at a pressure of a rate of at least about 45 pounds per square inch into a sheet of fluid having a velocity greater than about 900 feet per second.
- 10. A water spray tool according to claim 1 wherein the first, second and third nozzle portions are adapted to form a fluid stream flowing at a rate of at least about 4.9 gallons per minute at a pressure of a rate of at least about 40 pounds per square inch into a sheet of fluid having a velocity greater than about 500 feet per second.
- 11. A water spray tool according to claim 1 wherein the first, second and third nozzle portions are adapted to form a fluid stream flowing at a rate of at least about 4.9 gallons per minute at a pressure of a rate of at least about 40 pounds per square inch into a sheet of fluid having a velocity greater than about 600 feet per second.
- 12. A water spray tool according to claim 1 which further comprises a valve mounted on the body and which is operable to control a flow of fluid through the body of water spray tool.
- 13. A water spray tool according to claim 1 which further comprises a valve for controlling a flow of liquid from the vessel to the water spray tool.
- 14. A water spray tool according to claim 1 further comprising a hollow body having a flexible portion.
- 15. A water spray tool according to claim 1 further comprising the body lower end having a first coupler and the nozzle having a second coupler removably engageable with the first coupler.
- 16. A water spray tool according to claim 1 which further comprises;
- the nozzle having a raised portion;
- a mounting bracket including a bottom wall having a channel, and first and second flanges extending upwardly from the bottom wall;
- the mounting bracket removeably mounted on the nozzle and the nozzle raised portion received in the mounting bracket bottom wall channel.
- 17. A water spray tool according to claim 16 further comprising at least one cleaning implement mounted on the water spray tool.
- 18. A water spray tool according to claim 17 wherein the cleaning implement includes first and second channels, and respective first and second portions of the mounting bracket slidingly received therein.
- 19. A water spray tool according to claim 17 wherein the mounting bracket includes first and second channels, and wherein respective first and second portions of the cleaning implement are slidingly received therein.
- 20. A water spray tool according to claim 19 wherein the mounting bracket includes a spacer between the first and second flanges, the mounting bracket having surfaces defining said first and second channels.
- 21. A water spray tool according to claim 16 wherein at least one cleaning implement mounted on the water spray tool is selected from the group consisting of a brush, a squeegee, and a sponge.
- 22. A water spray tool according to claim 1 further comprising:
- a spring urging the valve toward its first position;
- a valve operating member connected to the valve and operable to move the valve between its first and second position.
- 23. A water spray tool according to claim 22 wherein the valve operating member is pivotally connected to the body, and wherein the spring bears on the valve operationg member.
