Hi. Curious on thoughts on these models and the justification for the price difference. On Amazon the current sale price for the S20 Pro is listed at $339.99 while the S30 non pro model is listed at $279.99. Comparing the 2, it seems the S30 is an improvement in most categories, but the self drying and cleaning is a higher temp in the S30, and the S30 lacks the detergent self dispensing chamber.

Is the $60 price different for S20 pro mostly just for the detergent chamber? Curious if I'm missing something or if the $60 difference is really just for a bit of convenience.
