New suction-cup system spins water to stick to rough surfaces

What about ferromagnetic fluid? You can still spin it if you are aiming to push it 'centrifugally' into the features of the vacuum boundary, but you shouldn't lose a lot during the detachment.

(Plus it looks much more sci-fi.)

Arduino controlled real live squid with water backpack. That’s the future.

I wonder if some sort of jelly would work to do the same thing, like a snail. Or a dynamic cup surface that conforms to the wall better.
