Which robot vacuum models have mopping docks, and what should I look for in the dock's features?

The Dreame L40 Ultra, ECOVACS DEEBOT X2 OMNI, [Roborock S](https://www.amazon.com/s?k=Roborock+S&tag=wehavethat-20)8 Pro Ultra, Samsung Jetbot Mop, and [Tineco Floor](https://www.amazon.com/s?k=Tineco+Floor&tag=wehavethat-20) One S3 all come with mopping docks. Don’t just check the box — check what the dock actually does: some wash pads with clean water and scrub them, others just spray them down, and some dry them afterward to prevent smell while others leave that to you.
