Claim:
A pressure washer wand assembly configured to discharge pressurized fluid in a changeable spray pattern, the wand assembly comprising: a rigid tube portion having an input end and an output end defining therebetween a longitudinal axis; a nozzle coupler attached to the rigid tube portion and including a single passageway that is offset from and not symmetric about the longitudinal axis; a nozzle assembly index having a plurality of selectable nozzles, the nozzle assembly index disposed downstream of the passageway and configured to discharge the pressurized fluid in a spray pattern, all of the pressurized fluid passing through the passageway before being discharged through any of the selectable nozzles; a nozzle assembly collar coupled for co-rotation with the nozzle assembly index, at least a portion of the nozzle coupler being received within the nozzle assembly collar for rotatably supporting the nozzle assembly collar thereon; a seal positioned between the nozzle coupler and the nozzle assembly index, the pressurized fluid in the tube portion first passing through an aperture in the seal prior to being discharged through one of the nozzles; a nozzle indicator disposed upstream of the output end that indicates a spray characteristic of a selected nozzle; and an elongated outer housing coupled for co-rotation with the nozzle assembly index and containing therein substantial lengths of the tube portion, the nozzle coupler, the nozzle assembly index, and the nozzle assembly collar, wherein the housing is configured to rotate with respect to the tube portion to select the selected nozzle.
