The coppertone model (Pic 1) has a Pre Wash cycle preceding Normal but it doesn't have a Soak cycle. I wondered for a moment why it needs a detergent dispenser with no Soak-to-Wash option but the Pre Wash (presumably including a drain and spin) is the reason.
Pic 2 has the full-meal-deal of Pre Soak and Pre Wash leading into Normal, thus the Soak selector switch.
