I know there were a lot of simple vac only bots in the roborock line up. S5 and similar the mopping funciton is a small pad that you manually wet and it drags along behind. It kind of sucks but if you were in the market for just a vacuum, you remove the bracket and it's fine. The robot has no knowledge of the mop as there isn't a tank.

The S6Max that has a tank, you can also remove (easily, two button clips) and it'll not attempt any mopping feature. It also supposedly doesn't squirt water on to the pad when it knows its on carpet, but at some stage you may be dragging a mildly damp cloth on to the carpet. (was never an issue for me, the pad was never that wet that you could reasonably detect it on the carpet)

Overall mopping with drag-behind pads is pretty... opportunistic? Its not great and you'll be in a position where you have to manually mop. Many models are switching to the spinning buffer pads which is a much better solution (that's the Dreame W10) but it refuses to do carpet. So its always a matter of finding a model that fits your use case.

>That means I would need two vacuums anyway as they haven’t learned yet to climb stairs.

Many allow for multi floor mapping on a single bot, but stairs will always be a problem for the Daleks. :P

S5 works the same like you describe S6Max, maybe you're thinking about some older one.
