Best automatic lawn mower for a small, uneven yard in central Texas

I've been struggling to keep my yard in shape lately, it's about 1/4 acre with some slopes and uneven patches, and I just can’t seem to keep up with regular mowing. I’ve tried a push mower and even a basic robotic one a few years ago, but it either got stuck on slopes or didn’t handle the thicker grass well.

I’m looking for a reliable automatic option that can actually manage these uneven areas without me having to babysit it all the time. Does anyone have recommendations for models that handle slopes and rougher patches, ideally something durable for Texas heat? Any tips on setup or maintenance would also be super helpful. Thanks!
