The first video is the normal sprays when an agitated rinse is also done. Sprays are at 300 RPM.
Second video is the Eco shower option without an agitated rinse. Saturation sprays are at 25 RPM.
That's the original spray flume. AquaSmart HE/impeller models brought in a revised flume that sprays more toward the left onto the clothes pancake and a stream aimed above at the surface of the basket. The revised flume was sequed onto agitator models after AquaSmart.
Some agitator models have set-up options to adjust the volume of water for the shower rinse (normal, less, least), and the software may slightly vary the number and duration of sprays according to the load size.
