There are a few mistakes on what is quite a good website. Having sold the almost identical Thompson twin tubs spin speed is gonna be about 1350rpm. I think these machines come with the same motors and design looking at the exploded parts diagram.
Indeed, just one or two mistakes!!! I too saw those balls. I have a pair in my dryer and they are supposed to eliminate the need for softener. A similarly dubious claim but not as bizarre as the water saving :-S
Other models have more realistic spin speeds. This baby for example is slow in comparison - a mere 7000 rpm.............
