A fluidic circuit configured to spray an oscillating pattern of fluid droplets, having an inlet in fluid communication with a source and including a power nozzle with an oscillation chamber having a fluid jet steering section in fluid communication with the power nozzle and having either (a) a first fluid pressure accumulating volume opposite a second fluid pressure accumulating volume or (b) a first fluid jet attachment feature opposing a second fluid jet attachment feature. The fluid jet steering section is in fluid communication with and emits a fluid jet into an oscillation inducing interaction region with opposing first and second side wall ears or features which define an oscillation inducing interaction region in the oscillation chamber for causing the jet of fluid to rhythmically sweep back and forth between the sidewalls in the oscillation chamber and create a distally projecting oscillating spray.
