Frustrating and lacking! I tried multiple mapping runs over several days, but the vacuum couldn't "see" past a line where tile and hardwood meet, leaving certain rooms in my house unmappable. After several days, I was able to get some of the rooms mapped, and attempting the vacuum and mop feature. The floor only had two wet streaks where the cleaner comes out onto the mopping pad, so I tried pre-wetting the pad. That worked a little better, but once it dried, I was down to two streaks, which did literally nothing to my floors. Once they dried, any marks, footprints, etc was still there. So disappointing and absolutely not worth the price. If I just wanted basic vacuuming without the smart mapping and mopping features, I could have found a better solution for half the price.
