Narwal Freo X Ultra Robot Vacuum and Mop Combo, 8200Pa Robot Mop & Vacuum, Auto Mop Drying/Washing, Self-Empty, Zero-Tangling, DirtSense™, Maintenance-Free Base Station, Self-Contained Dust Processing

I've owned iRobot Vacuums pretty much since they've been invented, and I ended up trading in both our mop robot and a vacuum for the Freo and was not disappointed. Today, we still have an iRobot S4, which is fairly current, and without a doubt, this machine destroys them all.First, it's worth mentioning that LiDAR is a game changer. Unlike older technology that relies on infrared, LiDAR presents a significant upgrade in obstacle detection, which allows the robot to create optimized plans. This dramatically speeds up vacuuming and mopping.One of the marquee features is the fact that hair is not only captured but also does not tangle the rollers. On an iRobot, the tangled hair must be addressed constantly, or else the rollers will tear. On this machine, nothing tangles the rollers at all.In general, I've found the robot to be more hassle-free, faster, and it leaves my floors far cleaner than any combination of robots that I've owned.The app is the one weak area - the UI is complicated and obtuse. There are typos and grammar errors.Another somewhat weak area is that there is a good amount of cleaning that needs to happen. You need to do more than empty the vacuum and change the mop pads. The tray needs to be cleaned regularly, and the robot requires its various parts to be removed and addressed perhaps every 1500 sq ft of cleaning or so.Despite these minor gripes, the machine feels durable, and ours looks and works like new despite regular use. Our house has some larger rooms, but we have no issues running the machine for several hours continuously. The machine charges quickly, and we hardly ever notice issues.I can't comment on suction for carpets, but for wood floors, it more than suffices, and we are generally pleased. We don't see much of anything on the ground, so from our perspective, it is able to pick up what it needs to do and gets the job done.Overall, this is one of the best purchases we've made in years, and we are grateful.

Ok, I've had this one for a week. So I'll update in a couple months if things change. But....This is awesome. I owned a Roomva iRobot for the last two years. The kicker with them was when I needed customer service over a dust bin in the unit, and i was 1 week out of warranty/return for it because I bought it, put it aside until I really needed it, and when I finally instaled it, found it to be the wrong item. They told me to buy a new one of the right one and to bug off otherwise. iRobot's cleaning power was also substandard, mine being a pet vac, that left pet hair all over the corners of the room. So, I've had 2 years experience with a robot vac.The Narwal cleans most excellently. Once in a while a piece of hair will get stuck in the back wheel and come off when it is travelling back and forth, but otherwise, perfect. The robot auto-detects floor type, changing from mopping to not (and raising the mops) when moving to a carpet. Setting room areas and types is very simple. It has settings for tile, hardwood and carpet, as well as general (it figures it out). You can set no-go zones very easily. You can even define a room as a pass-thru to get from one room to another that you are mopping, but the room in middle you don't want dealt with.It detects obstacles so well. One time my son was in its way as it was on it's way to a room to clean and he wasn't going to move. It stopped about 9-12 inches away from him, then took a path around him. The Roomba would always be bumping into walls and furnature (softly, but still) to determine the extent of a room, but he Narwall has built-in optics and can detect obstacles before it hits them. So it doesn't bump the walls and furnature, but gets right up close to vacuum or mop the edges with accuracy. And even here, when it mops at the edges of a wall, it has a mode to move, swivel, move so that the mop brushes get right up the edge and clean very, very well.It also detects if an area is extra dirty, for which it will mop that area/room 2x, 3x even 4x (if this is the fist time for a really dirty area -- say a bathroom or laundry). After it mops so many square feet, or after a room (settable featured) the Narwal will go back and wash the mop heads to avoid cross-contamination of the dirt (very useful if coming from a bathroom, if you know what I mean).When complete, it cleans its mops and dries them. Sound can be set to quiet (takes longer) or strong (quicker, but louder) -- and at any level is not all that loud (compared to the Roomba emptying its dirt bin every 10 minutes with a 99 db vacuum!!).Yes, this is a $1,000 unit, and I had to think a few times before spending that much. But it is worth every penny. My only work is in keeping the dirty water disposed of, and the clean water bin full. (If you set the robot on room mode -- washing mop heads by room -- then it isn't that bad; leave it by area (smaller) and you will need to be present as the water likely will run out in the middle of the total task).So, that's my 1 week estimate. I'll come back in a few months to confirm or deny my initial findings. Right now: I love this thing!!
