Wish I could make this a 4.5 star review. The robot itself is 5 stars--IT IS AWESOME. I say this as a lover of robots who has an iRobot Roomba j7+, and a Braava Jet M6. The Roborock Qrevo S5V is quieter and far more efficient at cleaning than the Roomba and Braava Jet combined. It rarely (more on this later) gets stuck compared to the Roomba and Braava Jet which both got stuck fairly regularly, sometimes multiple times daily. The Roborock's mapping function is far superior and easier to use than the Roomba and Braava Jet (Roborock learned the terrain in just one pass), it also charges quickly and cleans more effectively. No go zones are easier to set up (they're actually learned rather than selected) than Roomba and Braava Jet and are consistently respected. The Roborock charges quickly and its cleaning cycle--vacuum then mop--is 90 minutes for ~1500 sq ft as opposed to an all day effort by the Roomba/Braava Jet. The Roborock washes and dries its own mop heads and you will be stunned and grateful when you empty the dirty water tank. I did buy the official Roborock floor cleaning solution, but haven't used it yet. Water alone seems enough to clean the floors!There are only two caveats: (1) you MUST wrangle any electrical cords in order not to experience the frustration of having to move heavy furniture to rescue your Roborock. One pass over one electrical cord is enough for the cord to remove one or both mop heads rendering the Roborock completely inoperable and stuck. Unwrangled electrical cords are like poison to the Roborock; the mop heads are the Roborock's Achilles heel. Invest some money in flat cord covers for electrical cords that lay across flooring (i.e. for recliners or lamps) and cable sleeve covers for the jumble of cords hidden behind beds, couches and desks. Cord and cable covers are quite inexpensive. Spend some thoughtful time in organizing and protecting the cords--you''ll be so thankful you did!Caveat (2) is the app's user interface. If I could take half a star off, this would be why. In this regard the Roomba/Braava Jet is superior. The wording and layout of the Roborock app is curious and sometimes counter-intuitive leading to user frustration. There are times when I cannot remember the steps needed to access frequently used options which should require only 1 or 2 steps. There seems to be no way to easily locate the Roborock other than by using the map. The map however is beautiful!One huge added BONUS for those who have read this far and a big ol' Easter egg for me (I had no idea until I got the Roborock set up) is the ability to use the Roborock on multiple floors. You can do the additional floor mapping when you first set up the app or add it later. I only learned about this feature after setting up my Roomba and Braava Jet upstairs before unboxing the Roborock. The only downside I can see is having to carry (and remember to carry) the Roborock up and down the stairs.
