Versatility is well-supported by evidence that it handles vacuuming and mopping across hard floors, carpets, tile, and hardwood in one run.

The system relies on clean and dirty water tanks in the dock and an internal water tank in the robot, which keeps mopping more automated than vacuum-only robots. Expect periodic refills and dirty-water emptying, and some coverage mentions a future-leaning option for auto fill and drain via plumbing.

Water-system evidence is mixed: the dock has clean and dirty tanks, but some reviewers mention smaller tanks or refilling hassle.
