Getting back to the actual topic about the clean button, one of my customers calls it his snooze button. According to him, he used to hit his snooze 2 or 3 times every morning before he got up and got cleaned up for work.
Since he's had his Sovereign, he gets up at the first alarm, grabs a cup of coffee, hops in his tub, and hits the clean button. Once it goes off he knows it's time for him to get in the shower and get ready for work.
Not necessarily what Hot Spring had in mind when they put it on there, but another great use for it!
