No, the 1S has no mop function and is made by Roborock. However, the Mi Robot Vacuum Mop Pro is made by Viomi, it is basically a Viomi V2 Pro i.e. getting spare parts is very difficult. Instead of the Mi Robot Vacuum Mop, I would go for the Roborock S5 Max or the S6 Pure because Roborock spare parts are much easier to get. The Roborock S6 Pure is better, quieter, has better features and costs almost the same as a Mi Vacuum Robot Mop Pro.
