## Abstract

An improved bidet device is set forth which includes a self cleaning spray tube having a housing with a first open end with respect to a water supply and a second open downstream end. A nozzle disposed within the housing, the nozzle having a plurality of radial holes therethrough and being adapted to receive water from the first open end of the housing. A spring wound about the nozzle, the spring tending to to retain the nozzle within the housing. Whereby water delivered to first open end of the housing flows through the radial holes of the nozzle, such that water is discharged from the holes and urges the nozzle to move from a first nozzle position within the housing to a second nozzle position outside the housing. Water discharged from the radial holes bathes an external surface of the nozzle such that the nozzle is self-cleaning. A method for cleaning a nozzle having a water supply is also disclosed.

## Claims

### Claim at position 1

1-12. (canceled)

### Claim 13

A method of cleaning an external surface of a nozzle including a plurality of holes along a length thereof and a collar at end one for retaining a coil spring in place therearound comprising the steps of:
directing water to said housing containing the nozzle having a first open end and a second downstream end, the first open end in communication with a water supply;
directing water into a cavity of the nozzle and through the plurality of holes along a length thereof to clean said external surface of the nozzle while the nozzle remains in the housing before directed water compresses the coil spring thereby forcing the nozzle from a first nozzle position within the housing to a second nozzle position outside of the housing allowing directed water and fecal matter from the housing and nozzle to drain into a toilet bowl; and
ceasing directing water thereby causing said coil spring to extend and the nozzle to automatically return to the first nozzle position when said water supply is turned off.

### Claim 14

(canceled)

### Claim 15 (depends on 13)

The method of claim 13 further comprising coupling the housing with a tube of a bidet device.

### Claim at position 5
