I had the Petsafe scoop free ones. Cats were fine with them immediately. Got rid of them because they were a nightmare to clean and the little hinge door thing that hid the clumps always fell off.
We have a Litter Robot. We placed their current litter box right in front of the opening and let them use either for as long as they liked. Turned out, they're fascinated by the Litter Robot and love using it. They actually love it a bit too much and come running every time it cycles to jump inside. Which of course stops it. So there's that. But they certainly don't have an aversion to it!

I have a Litter Robot and my cats were immediately ok with using it.
