Hi Peter, in this machine I mainly use the 10-minute wash time on the Regular cycle, although every once in a while I'll use Permanent Press. The maximum wash time on Regular is 14 minutes which may not be the gentlest on clothes, but still nothing compared to the "Heavy" cycle on the GE! I haven't been brave enough to try that (nor have I had any loads dirty enough to warrant using it), especially seeing as how the Normal cycle is longer than that on the others.
Last week I did a mixed load with a couple of pairs of jeans and some shirts. It was definitely a capacity load, but the Roto-Swirl did surprisingly well with good, steady rollover...better than I remember it ever doing in the Frankenmore. The smaller, narrower tub which it was designed for must have helped.
I like the RS, however, the real "brute" (as GyraSteve puts it) is the straight-vane. Talk about some action, no doubt *that* would cause premature wear at 14 minutes!
