I have seen the KA FL machines at the Western Appliance in San Leandro.
The first time I saw one was a couple of years ago. If I'm not mistaken, that one had a darker gray cabinet, and it was stunning. The most recent versions appear to be a bit lighter, and not as dramatic, but still very nice.
Wet washing fabric depends upon three energy inputs: thermal, mechanical, and chemical. All three are intensified by time. So, for the very whitest whites, the Sanitary option could be used. Me, I get very white whites with my 130F Neptune 7500. I use every trick to extend the time of the wash cycle, so that the total cycle time is 109 minutes. I also use a phosphated detergent, and the results speak for themselves. If I had a machine that went to a higher temp, I would wash the whites up to 160F. Above that, I'd probably only wash stuff without elastic.
I sometimes use the 109 minute 130F cycle for work clothes that are especially dirty. I work in a metal shop and when I have to service one of the big machines, my shop/lab coat can get pretty grimy. I can also muck up jeans and shirts pretty good when working at home on one of my vintage cars or in the garden.
