I have an ecovacs deebot n79S and it just uses a remote. You put it on auto and let it do its thing. The pathfinding isn’t great but it does the job and you can manually control it if needs be. There is an option for connecting an app but thats not happening. As long as it comes with a remote you should be good.
I should also add that its easy to clean and pop the front wheel and rear brush out as well as the 2 spinning brushes. The dust compartment slides out easily too.
We have had it for about 2 years so far and it still runs fine.
