That tech was launched over here some time ago, and makes it to the US apparently, though only in compact units.

The idea of an element of the drum turning opposite to the rest of the drum and thus increasing mechanical action which allows for shorter wash times is nothing new.
First implication I can think of was the pulsator disc in some Hoover Keymatics (somewhat related to the Westinghouse FLs of the early times AFAIK).
Then came James Dyson in the early 2000s. Expensive and failure prone with a complicated planetary gear case on the back of the drum they weren't long lived.
Now Samsung is doing it, with the backplate of the machine turning.
On paper it works (EU standard cycles at 3h with incredible efficency for that time, normal Cottons cycle down to an hour, SuperSpeed at just 39min).
However it does add a lot of complicated components (second, independently controlled motor; a bearing somehow integrated into the achsel of the actual drum) in a verry small space.
Oh, and the few videos out there are of the spin cycle mostly and - for what ever bizarre reason - the back of the drum is static during that. Not sure if that might cause snagging, friction and tearing issues for the clothes.
What do you guys think?
