The Narwal Freo X Ultra is one of our favorite robot vacuums for mopping. It features a commendable 8,200Pa of suction power and a host of welcome features, including a set of spinning triangular mops that allow it to clean hard surfaces exceptionally well. It can adjust the amount of pressure applied by its mop based on floor type, too, and can even make its own "cleaning decisions," one of which will prompt it to remop your floors if they remain dirty after its initial pass. It can also clean its own mop pads and offers support for several voice assistants, including Amazon Alexa and Google Assistant.
