A water flow operated device for winding and/or unwinding a length of flexible material. The device includes a stationary element, a spool with a central axis rotatably engaged by the stationary element and a water flow operated mechanism engaged by the stationary element. The water flow operated mechanism serves to controllably rotate the spool. The water flow operated mechanism includes a water operated motor, a water inlet communicable with a household water source, a water outlet and a valve for controlling a flow of water through the mechanism.

1. A water flow operated device for winding and/or unwinding a length of flexible material, the device comprising:(a) a stationary element;(b) a spool having a central axis, said spool being rotatably engaged by said stationary element and being rotatable about said central axis; and(c) a water flow operated mechanism being engaged by said stationary element for controllably rotation said spool, said water operated mechanism including:(i) a water operated piston motor having at least two water operated pistons mechanically linked to said spool, and a distribution valve assembly for selectively directing water to said pistons so as to rotate said spool;(ii) a water inlet for directing water into said water flow operated mechanism, said water inlet being communicable with a household water source;(iii) a water outlet for directing water out of said water flow operated mechanism; and(iv) a control valve for controlling a flow of water through said water flow operated mechanism. 2. The device of claim 1, wherein said at least two water operated pistons are implemented as at least three water operated pistons. 3. The device of claim 1, wherein said water operated piston motor is configured to be operated by a domestic water supply. 4. The device of claim 1, further comprising said flexible material being at least partially wound on said spool. 5. The device of claim 4, wherein said flexible material is selected from the group consisting of a hose, a rope, a cable, a chain and a wire. 6. The device of claim 4, wherein said flexible material is a hose, and wherein said water flow operated mechanism is fluidally communicable with a first water source and said hose is fluidally communicable with a second water source. 7. The device of claim 1, wherein said control valve has at least two operation states, an open operation state and a closed operation state. 8. The device of claim 1, wherein said control valve has at least two operation states, an operation state which directs water away from said water flow operated mechanism. 9. The device of claim 8, wherein said operation state which directs water away from said water flow operated mechanism directs water to a channel being fluidally communicable with a hose. 10. The device of claim 1, wherein a direction of rotation of said water operated motor is reversible such that the winding and unwinding of the length of flexible material are both performable by said water operated motor. 11. The device of claim 1, wherein said control valve has at least three operation states, a first operation state which directs water into said water flow operated mechanism, a second operation state which directs water to a channel being fluidally communicable with a hose and a third operation state which is a closed operation state. 12. The device of claim 1, wherein said control valve is selected from the group consisting of a linear selector valve and a rotating selector valve. 13. A water flow operated device for winding and/or unwinding a length of flexible material, the device comprising:(a) a stationary element;(b) a spool having a central axis, said spool being rotatably engaged by said stationary element and being rotatable about said central axis; and(c) a water flow operated mechanism being engaged by said stationary element for controllably rotating said spool by connection to an output linkage, said water operated mechanism including:(i) a static-pressure-responsive water operated motor configured for driving said output linkage through unlimited revolutions;(ii) a water inlet for directing water into said water flow operated mechanism, said water inlet being communicable with a household water source;(iii) a water outlet for directing water out of said water flow operated mechanism; and(iv) a valve for controlling a flow of water through said water flow operated mechanism,wherein said valve has at least two operation states including a first operation state in which said valve directs water into said water flow operated mechanism for subsequent release to a drain and a second operation state in which said valve directs water away from said water flow operated mechanism, wherein said second operational state directs water to a channel in fluid communication with a hose. 14. The device of claim 13, wherein said water operated motor is implemented as a water operated piston motor having at least two water operated pistons mechanically linked to said spool, and a distribution valve assembly for selectively directing water to said pistons so as to rotate said spool. 15. The device of claim 14, wherein said at least two water operated pistons are implemented as at least three water operated pistons. 16. The device of claim 13, wherein said water operated motor is configured to be operated by a domestic water supply.
