Abstract: In an embodiment, a rotating nozzle including a generally cylindrical interior having an inlet at a circumferential wall adjacent a first end of the body portion and a generally axial exit adjacent a second end of the body portion. A nozzle portion is at least partially received within, and rotatable relative to, the cylindrical interior. The nozzle portion includes an at least partially conical shape, having a relatively smaller cross section adjacent the first end of the body portion. The nozzle portion defines a generally longitudinal flow passage having an inlet opening extending between an exterior of the nozzle portion and the flow passage adjacent the first end of the body portion and a generally axially oriented exit adjacent the second end of the body portion. The rotating nozzle further includes end cap disposed at least partially enclosing the cylindrical interior adjacent the first end of the body portion.

Abstract: An electrical pressure washer includes a diagnostic circuit for detecting operation conditions that may affect the normal operation of the pressure washer, and a plurality of indicators indicating the detected operation conditions, such as ground fault, low pressure, overheating, etc. A voltage drop across the power cord of the pressure washer is monitored and used to identify several of the operating conditions. A way of connecting and controlling light-emitting diodes used as indicator lights is provided to allow energy-efficient operation of the indicator lights.
