Question about Roborock S5 Max

That's relatively easy to answer, you get the best navigation with the Roborock S6 MaxV, it has 3D object recognition with cameras and a built-in database.

But for wet mopping, the S7 would be the best, as it can lift the mop top on carpet (pointless on long haired carpets of course, as this lift is not very high) and it would have an optional suction station.

An S6 MaxV, S5 Max or S7, they all clean very well. The navigation is the best with the S6 MaxV, because the others can only navigate with infrared and laser, the S6 MaxV can do that too, but it can also recognise the objects as such, e.g. a lamp base, a scale, shoes and power strips, the other Roborocks cannot do that.
