Question about iRobot Braava 390 T

I assume that cat tracks are removed. He wipes over it several times and the microfibre cloth picks up dirt well. But I don't have a cat, so it's a guess. I always take the carpet away. It doesn't make sense to wipe the carpet wet or to go over it with a swiffer cloth. If the carpet is high, he would see it as an obstacle and avoid it. He also sees doorsteps as obstacles, just like stairs. So he wipes along the edge and doesn't fall off.

I can't judge cat jumping because I don't have one. He notices when he comes to a landing and looks for another way. Depending on the height of the carpet, he recognises the floor covering. I remove all carpets, but I only have two small footstools.
