I'm very impressed with this robot vacuum and mop duo!  It's smart technology scans and maps your house Floorplan, and you can send it specifically to a particular room.  The mop feature is really quite fascinating, and it does not leave your floor super wet, just damp. I love that it uses a microfiber mop pad!  It knows when to go fill its reservoir with water from the main tank and also knows when it's full of debris and needs to go empty itself. It's truly a no touch system in the sense that I've never had to deal with it since setting it up!!  The technology is amazing!  It's mostly quiet when running and leaves behind nice straight vacuum lines, which is love!  My only recommendation to Shark would be to work on the battery life. It does not last very long before it needs to go back to the base to recharge (which takes up to 3 hours).
