## Abstract

A water jet cleaner for the underside of a vehicle. A plurality of jets are directed upwardly from a spray head which is mounted on a longitudinal member positioned closely to the ground on which the vehicle is resting. A handle is attached to the longitudinal member and wheels are mounted to the frame and the longitudinal member to allow manual reciprocal movement of the cleaner beneath the vehicle by an operator. The jets are angularly adjustable such that the cleaner may also be used to clean the surface itself such as a driveway.

## Claims

### Claim 1

A water broom having a spray head operable to emit fluid in a generally upwardly direction from a plurality of jets mounted in a frame, said frame being mounted on wheels, said wheels each having an axis, a longitudinal member operably connected to said frame, said member extending generally normal to said frame, a handle mounted to said longitudinal member and extending generally upwardly for a distance ending approximately at the position of the hands of an operator, said plurality of jets having an angular orientation which is adjustable so as to allow said jets to emit water in an upwardly or downwardly direction, said axis of said wheels on said wheel mounted frame being in a fixed configuration relative to said frame, said handle including a fitting for attachment to a hose and a switch for opening or closing the sul of water from said hose, said frame being rotatably adjustable relative to said longitudinal member between at least two positions, the first of said two positions being directed generally upwardly and the second of said two positions being directed generally forwardly and downwardly.

### Claim 2 (depends on 4)

A water broom as in claim 4 and further comprising a bracket between said frame and a circular end of said longitudinal member, one of said bracket or said circular end of said longitudinal member having serrations and the other of said bracket or said circular end of said longitudinal member having a ridge complementary to and movable within said serrations.

### Claim 3 (depends on 1)

A water broom as in claim 1 and further comprising a cam member rotatable within a race, said cam member maintaining said frame at a predetermined angle when said cam is in firm contact with said race.

### Claim 4 (depends on 3)

A water broom as in claim 3 wherein said predetermined angle of said frame is adjustable between said first and second positions.
