Yes, this robot has a wiping function, but it is a bit of a fiddle and the wiping tank shares space with the cleaning tank inside the robot. The Xiaomi Dreame is much better, it is comparable in quality and performance to a much more expensive Roborock S5 Max or S6 (they cost around 400 Swiss francs). The Xiaomi Mi Mop Pro device is made by Viomi, which is also good, but the Roborock and Dreame robot hoovers are much better.

The Xiaomi Dreame D9 is a top of the range robot hoover and I would recommend it, don't think because it costs under 250 it's bad, it's much better than the Mi Mop Pro :).

Xiaomi Dreame D9

The Dreame has a much larger dust bin than the Mi Mop Pro, spare parts are easier to get thanks to the similarity with Roborock models, the tank with the mop simply clicks onto the bottom of the Dreame D9 and you're ready to go.
