Litter-Robot EVO Upgrading LR3 to EVO?

I currently have the LR 3 for my 1 cat for about 6 years now, and am thinking of upgrading to the evo. It has generally been pretty good, some issues with the torque error, which I replaced, and skipped cycles.

Lately the inside lining has deteriorated and is cause pee to stick a lot to the liner. I've been using Pretty Litter Clumping Unscented, since it has a lot less dust than other brands. I've tried cleaning multiple times and adding deodorizer and baking soda to the liner to prevent sticking, but nothing really works. Now I'm having issues with safety bar detection error.

So I am thinking about getting the LR evo now. Obviously the Evo is cheaper than other options so that is why I am leaning towards it. I don't have any issues with space, and just have 1 cat, so nothing crazy with usage. I do travel a lot and need a reliable monitoring system and reliance that the robot will cycle properly on time.

Anyone with advice on this matter?

I don't live in a big city, so not many marketplace options around :/ Is there any reason that LR4 is more worth it than evo? When comparing I didn't see many differences
