a first mode of operation defined when the spout nest is coupled to the docking cradle, and the sprayhead is coupled to the spout nest whereby the sprayhead is held in a fixed position relative to the docking cradle;

a second mode of operation defined when the spout nest is removed from the docking cradle, and the sprayhead is coupled to the spout nest whereby the spout nest and the sprayhead are moveable together both vertically and horizontally; and

a third mode of operation is defined when the spout nest is coupled to the docking cradle, and the sprayhead is removed from the spout nest whereby the flexible tube is extendable out of the spring spout whereby the sprayhead is spaced from and moveable relative to the spout nest.

2. The faucet of claim 1 , further comprising a magnetic coupling releasably coupling the sprayhead to the spout nest.

3. The faucet of claim 2 , further comprising a magnet and a sprayhead retainer to secure the magnet to the spout nest, and a magnetically attractive member secured to the sprayhead.

4. The faucet of claim 1 , further comprising a spout base coupled to a first end of the spring spout, and a support arm having a first end coupled to the spout base and a second end supporting the docking cradle.

5. The faucet of claim 4 , wherein the spring spout includes a helical spring.

6. The faucet of claim 4 , wherein the docking cradle includes a c-shaped retainer configured to engage the spout nest.

7. The faucet of claim 4 , wherein the docking cradle includes a magnet configured to releasably couple to the spout nest.

8. The faucet of claim 4 , wherein the first end of the support arm is supported for rotation about a longitudinal axis of the spout base.

9. The faucet of claim 1 , further comprising a fourth mode of operation defined when the spout nest is removed from the docking cradle, and the sprayhead is removed from the spout nest.

10. The faucet of claim 1 , further comprising:

a capacitive coupling between the spout base and the spring spout;

a capacitive sensor operably coupled with the spring spout through the capacitive coupling;

a controller operably coupled with the capacitive sensor; and

an actuator driven valve fluidly coupled to the flexible tube and controlled by the controller.

11. The faucet of claim 1 , wherein the spout nest comprises:

an upper flange;

a lower flange; and

an annular groove defined between the upper flange and the lower flange, the annular groove configured to receive the docking cradle.

12. The faucet of claim 1 , further comprising:

a spout base; and

wherein the spring spout includes a helical spring having opposing first and second ends, the first end coupled to the spout base.

13. The faucet of claim 12 , wherein the spout base comprises:

a spout upper tube;

a retaining sleeve supported within the spout upper tube; and

a connector tube coupled to the spring spout, the connector tube rotatably supported by the retaining sleeve.

14. A method of operating a kitchen faucet comprising the steps of:

providing a spring spout having a first end secured to a spout base and an opposite second end, a spout nest coupled to the second end of the spring spout, a sprayhead releasably coupled to the spout nest, a flexible tube coupled to the sprayhead, the flexible tube extending through the spring spout and being slidably extendable from the spring spout, and a docking cradle configured to releasably couple to the spout nest;

coupling the spout nest to the docking cradle;

coupling the sprayhead to the spout nest;

removing the spout nest from the docking cradle whereby the spout nest is movable both vertically and horizontally relative to the spout base; and

removing the sprayhead from the spout nest whereby the flexible tube is extendable out of the spring spout and the sprayhead is spaced from and moveable relative to the spout nest.

15. The method of claim 14 , further comprising the step of recoupling the spout nest to the docking cradle before the step of removing the sprayhead from the spout nest.

16. The method of claim 14 , wherein the sprayhead is magnetically coupled to the spout nest.

17. The method of claim 14 , further comprising the steps of providing a spout base coupled to a first end of the spring spout, and a support arm having a first end coupled to the spout base and a second end supporting the docking cradle, and rotating the support arm about the spout base when the spout nest is uncoupled from the docking collar.

18. The method of claim 14 , wherein the step of coupling the spout nest to the docking cradle includes receiving the docking cradle within an annular groove of the spout nest.

19. A faucet comprising:

a spout base;

a spring spout including a helical spring having opposing first and second ends, the first end coupled to the spout base, the second end being both vertically and horizontally moveable relative to the first end;

a flexible tube supported for sliding movement within the spout base and the spring spout whereby the flexible tube is extendable from the spring spout;

a spout nest coupled to the second end of the spring spout;

a sprayhead fluidly coupled to the flexible tube and releasably coupled to the spout nest wherein the flexible tube is extendable out of the spring spout to thereby space the sprayhead from the spout nest and allow relative movement between the sprayhead and the spout nest when the sprayhead is released from the spout nest;

a docking cradle supported by the spout base and configured to releasably couple to the spout nest; and

a support arm having a first end operably coupled to the spout base separate from the first end of the spring spout, and a second end supporting the docking cradle for movement independent of the spring spout.

20. The faucet of claim 19 , further comprising a magnetic coupling releasably coupling the sprayhead to the spout nest.

21. The faucet of claim 20 , further comprising a magnet and a wand retainer to secure the magnet to the spout nest, and a magnetically attractive member secured to the sprayhead.

22. The faucet of claim 19 , wherein the docking cradle includes a c-shaped retainer configured to engage the spout nest.
