I haven't read many good things about Samsung appliances, they're all show but little substance. This video's portrayal of the "AI Wash" just reinforces it. As someone who works in tech, I found it nearly nauseating.
Part of why Whirlpool's this rack design can work so well is their very tall tubs, 10%+ taller than the previous generation of tall tubs. If Samsung hasn't gotten a similar amount of extra space, it's just going to cramp the second rack.
The spinning discs is a cool idea, but I think I'd just rather have stationary nozzles for less moving parts. That's more an opinion than a substantial concern. As echoed, they will break just because they're Samsungs.
