ABSTRACT:
A power washer wand has a loop or helix which balances the forces of the water stream. By balancing these forces, the back pressure is greatly reduced. This results in less fatigue for the user and also enables the wand to be extended in order to reach high or distant surfaces without the use of a ladder or scaffold. The wand may also include a universal joint. This joint allows the angle between the wand nozzle or tip and the surface being washed to remain substantially constant. The wand may be longer than conventional wands and may be connected to an extension.
