Abstract: Apparatus for spraying a fluid under pressure upward onto an undercarriage of a vehicle and downward onto an upward-facing surface. The apparatus includes a conduit adapted for connection to a pressurized fluid source for delivering fluid under pressure from the source and a spray assembly connected to the conduit for movement between an upward spraying position for spraying pressurized fluid toward an undercarriage of a vehicle and a downward spraying position for spraying pressurized fluid toward an upward-facing surface.

Abstract: A water spray apparatus for dual function use in washing motor vehicle undercarriages or in cleaning ground surfaces. The apparatus has a hollow cross tube axially supported by a pair of wheels and pivotally connected to a union. The cross tube has a row of commonly facing orifices for generating a row of commonly directed water streams. Directional reversal of the water streams is accomplished by pivoting rotation of the cross tube.
