Fabulous.  I've wanted one of these since they were introduced, now I want one even more.  I'll have to be more aggressive and thorough hunting for one now.

I thought he may have overloaded it, but those athletic clothes washed pretty well and the spin sloshing was excellent to watch.  You're right about that spinning during final rinse, Maytag did a similar program to keep the tub clean(er).  Whirlpool Duet also kept the drum spinning while admitting rinse water to flush the outer drum as well.  I can imagine trying to minimize build up in the tub is important for this stow-away, it would be like a humidor tucked back in it's hidey hole after use. 

Here is a vid of the same guy trying it empty for the first time.
