Narwal Flow 2 robot vacuum impresses with spot-on AI mess detection and heated mopping tech

Narwal Flow 2 robot vacuum review: The most spot-on AI mess detection I've seen yet

A Mashable Choice Award is a badge of honor, reserved for the absolute best stuff we've tested and loved. Robot vacuum releases for 2026 kicked off in February and have been relentless since. Compared to multiple pre-spring release dates, Narwal's April 13 launch of the Narwal Flow 2 feels a little behind. A new roller mop robot entering the fold at this point would need to have a little extra sparkle to stand out -- to the average buyer, and to me, a vacuum reviewer who has had at least three robot vacuum and mop combos under her roof at any given point since January. Seemingly nothing, if you were merely comparing the bullet points in the Flow 2's Amazon description to the Amazon listings for other robovacs in its price range. 31,000 Pa suction power? A self-cleaning roller mop? Dual camera AI object recognition? On paper, it's nothing we haven't heard before. In practice, though, the Narwal Flow 2's AI skills around obstacles and messes have proven more reliable than other 2026 flagships that claim the same thing. I've realized that the Flow 2's specs are actually loaded for how much Narwal is charging -- especially with the Flow 2 at its launch sale price of $1,099.99. 31,000 Pa suction is quite strong for barely costing over $1,000, and heated water mopping is hard to come across at all. The Dreamxe X60 Max Ultra Complete mops with hot water, too, but it's not a roller mop vacuum (and it costs more). Every big robot vacuum is flaunting AI-powered cleaning and obstacle recognition this year. The thing is, AI robot vacuum features mean nothing to me if they're dodgy. Most fancy AI robot vacuums I've tested recently seem to struggle with consistent mess detection, especially around liquid. The Narwal Flow 2 and its Freo Mind AI mode have been different, though. When Narwal says that the Flow 2 "sees everything," it's honestly not that much of a stretch. When upcoming piles of debris or liquid spills are substantial enough, the Flow 2's front-facing camera snaps a picture before adjusting its cleaning approach accordingly. For instance, the Flow 2 knew that tracked kitty litter around the Litter-Robot was "scattered debris." Suction power audibly boosts when the Flow 2 crosses any area it thinks is heavily soiled. Most AI robot vacs use live imaging like this for behind-the-scenes processing while cleaning, but photographic evidence of what the vacuum is seeing isn't always readily available. I appreciate that the Flow 2 is so transparent about its thought process -- it's been fun to make a mess on the floor, then immediately check the app to see if the Flow 2 accurately recognized it. Narwal's small obstacle avoidance has also been spot-on so far. The Flow 2 successfully avoids charging cords, shoes, and slippers on a daily basis, and even made it a point to steer around large clumps of potting soil (thinking they were pet waste). The app drops a little pin in the map, noting what type of obstacle it found, and you can see a photo of those, too. This is how I found out that the Flow 2 noticed more niche obstacles in its peripherals, like the very out-of-the-way power cord to my Mill food recycling bin and my cat's crinkle ball toys. The Narwal Flow 2 is a beast at soaking up liquid spills. Instead of the traditional cylindrical roller mop design, this roller has flat slides like a conveyor belt. Narwal says this covers 0.157 square feet of floor surface per pass, which is allegedly more direct surface coverage than the sliver of a rounded roller mop hitting the floor at any given point. I believe that. The Flow 2 was super effective at fully soaking up runny spills like wine and thicker droplet consistencies like ranch and pancake batter. Most notably, the Flow 2 left no sticky residue behind after mopping several drops of syrup -- and every robot vacuum struggles to fully wipe syrup up. This has to be due to the roller mop's use of heated water, which we rarely see in roller mop robot vacuums. The combination of heat with a pressurized flat roller seems to be an elite pairing for melting away caked-on grime. I realize that 140 degrees Fahrenheit isn't enough to kill bacteria by science's standards. But for me, the heated scrubbing provides an extra layer of sanitation (and subsequently, comfort) for walking around in bare feet. The Narwal Flow 2's rug cleaning is definitely in the top percentile of the many flagship robot vacuums I've tested since January. I'd unsurprisingly rank it just below the Dreame X60 Max Ultra Complete's 35,000 Pa, but would surprisingly rank it above the Roborock Saros 20's 36,000 Pa. If you just want to compare the suction power to other roller mop robot vacuums, the Flow 2 is a smidge better than the Roborock Qrevo Curv 2 Flow's 20,000 Pa. There's a lot of variety in the Narwal app's customized vacuuming settings. There are four suction options from "quiet" to "super powerful," plus the occasional pop-up option for "vortex suction," depending on the floor type. You can choose between a standard or meticulous route, the latter taking longer as the Flow 2 scrupulously cleans in two zigzag patterns, one running perpendicular to the first to create a crosshatch pattern. My favorite part is being able to choose up to THREE cleaning passes for extra good measure. I entrusted the Flow 2 with tackling daily rug buildup like shedded cat hair and long head hairs from my own personal shedding, small crumbs, and litter lodged in the fibers of my plush bath mats. All of those saw a 95 to 97 percent pickup rate. After recently watching the Dyson Spot+Scrub Ai miss a ton of tiny quinoa pieces that I dumped into the fluffy hallway rug, I experimented with the Flow 2's handling of the same exact mess. It went much better this time. The Flow 2's performance on hardwood and tile has been solid, too. I was constantly sending it to clean up kibble and crusted wet food flung from my cats' bowls, fallen dryer lint, and two types of cat litter. None of the missed debris or dust here and there has been egregious, confirmed by the laser on one of my Dyson stick vacuums. Not even a minuscule stem was left behind after the Flow took several passes over dried bouquet remnants that my cat knocked out of a vase. As helpful as the meticulous cleaning and navigational settings have been, they're sometimes granular to the point of being more complicated than they need to be. Narwal's cleaning settings were... hyper-vigilant when I wanted the Flow 2 to clean up a puddle of wine. No matter how many times I sent it to vacuum and mop this cleaning zone, the Flow 2 would clean the entire rectangle but the few inches with a wine splatter -- even though I could see in the app that a liquid spill was detected. It took me forever to figure out that I had the Flow 2 in a custom "vacuum and mop at the same time" mode, and that the Flow 2 didn't want to vacuum over a liquid spill. I'm obviously thankful that the Flow 2 won't just drive through a puddle and suck wine up into the dust bin, but I'm surprised that the Flow 2 can't tweak its cleaning strategy, regardless of whether it's in custom mode. A heads-up like, "I'm not ignoring this spill just to annoy you. Switch me to Freo mode!" would have been nice. After its initial mapping run, the Flow 2 quietly defaulted rug settings to "cross the carpet without cleaning it." That's the Freo smart cleaning system trying to avoid getting rugs wet when mopping, but that feels like an illogical extra step. Other premium robot vacuums automatically clean both floor types on the fly, and simply cut water flow and lift the mop on soft flooring. This setting is buried in the map management maze, and I don't think most people would assume that it's a setting they could even toggle. They'd just get pissed off that their new robot vacuum is refusing to vacuum the rug.

The Narwal Flow 2 an AI-forward robot vacuum and mop that uses its smarts to determine how dirty your floor is, and the best way to clean it

Narwal Flow 2: two-minute review I'll be the first to tell you that I have had a hate-love relationship with robot vacuums. However, over the years, I've watched as the technology has improved, resulting in better mapping, improved object avoidance, and exciting features. This is why I was all too glad to test the Narwal Flow 2 robot vacuum. Narwal introduced its 2026 flagship robot vacuum in January, which resulted in a lot of buzz. It's not the first robot vacuum to have dual cameras, but the way they work with the LM OmniVision AI Model feels like a big leap forward. During testing, I observed the Narwal Flow 2 robot vacuum recognizing the dirtiness of a floor and adjusting the suction and mopping capabilities. Plus, its ability to 'smart clean', or recognize which areas of your house need deeper cleans, and avoid and identify obstacles is next to none. Although I don't have pets or babies, the Pet Care Mode and Baby Care Mode are quite cool because they let the Flow 2 find your pet (and play with it), switch to quiet mode near cribs, and avoid crawling zones. Overall, I found the Narwal Flow 2 's smart capabilities very impressive, and its customization capabilities within the app particularly convenient. Its mopping capabilities are its best feature, and when paired with vacuuming, it does a great job of cleaning all floor types -- though it doesn't fare as well with edge or corner cleaning. The suction capability wasn't strong enough to pull super-fine materials like flour from a thick rug, but it did better than other robot vacuums I've tested. I would have also liked it to be half an inch shorter so it could fit under my kitchen cabinets. The Narwal Flow 2 stands out in other ways too, such as its ability to climb over high thresholds, app and voice controls, and video feeds. The dock automatically empties the dust cup, and washes and dries the roller mop with hot water and hot air. I still think you'll need a vacuum and a wet-dry vacuum on hand for deeper cleans or to reach spaces the robot vacuum can't go, but the Flow 2 will do a stand-up job at keeping your home pristine between deep cleans. The Narwal Flow 2 launched in the US in April 2026, with a premium price tag to match its high-end cleaning features. There are plenty of other great robot vacuums that are more affordable (even ones with cameras), but most don't have the AI capabilities of this model, which really set it apart from the competition. Narwal Flow 2: price and availability * Price: $1,499 (about £1,100 / AU$2,100) * Special price at launch: $1,099 (about £810 / AU$1,500) * Launch date: April 2026 * Availability: US The Narwal Flow 2 launched in the US on April 13, 2026, with a UK release expected at a later date. Although the list price for the robot vacuum and the base is $1,499, those who buy it during the launch can snag this combo for $1,099. It's available directly from Narwal and Amazon, but may expand to other third-party retailers later. The price makes sense considering that the Flow 2 is outfitted with high resolution cameras, a roller mop, and superb AI capabilities that lets it recognize shoes, cords, pets, and toys, and adjust the cleaning settings depending on the type of dirt, debris, or spill. The dock also has hot water and hot air-drying capabilities -- something that lesser models lack. We consider the Narwal Flow 2 to be a premium buy since it costs more than $800 / £650 / AU$1,000 . Our review model came with cleaning solution and one extra dust bag. Accessory replacements are available from Narwal. Now the question remains, is this model worth $1,499? Considering all the features and control users have through the app, I would say yes. I just wish the edge and corner cleaning had matched my expectations. Perhaps an update will improve both settings soon. * Value score: 3.5/5 Narwal Flow 2: design * Circular robot vacuum and a self-emptying and self-cleaning base * Anti-tangle mopping roller brush * Dual high-definition cameras with a wide view The Narwal Flow 2 is a black, circular robot vacuum that's about 13.5 / 35cm inches in diameter and has the capability to lift over thresholds. At 3.7 inches / 9cm, the robot vacuum is relatively tall, and even though it can fit under my couch and baker's rack, it doesn't fit under my cabinets. It has a small rotating brush along the bottom edge that sweeps debris toward the zero-tangling floating brush, where the robot vacuum uses 30,000Pa to suck up debris. The Flow 2 uses a crawler mop for edges; think of it like a roller map that has been flattened so that it's wide, long, and rotates, using 12N downward pressure to clean floors. The crawler mop can extend 1.8 inches / 5cm from the side. The robot vacuum comes with a black base that's 20.5 / 36cm inches tall, 14 inches / 36cm wide, and 17 / 43cm inches deep, and a cord that is 4.8 feet / 1.5m long. Separate clean water and dirty water tanks sit on top of a tank that holds the cleaning solution. Both the robot vacuum and the dock have filters. The dock also features a dust bag that can last up to 120 days, and colored ambient lighting, which can indicate different things like when there is problem with the robot (eg flashing red lights).I n addition to LED lights on the robot vacuum itself, the Narwal Flow 2 has dual 1080p cameras with a 136-degree field of view. The robot vacuum uses cameras and AI to recognize objects or pets and either avoid them or note them on the map, captures video and photographs, and provides deeper cleanings. * Design score: 4.5/5 Narwal Flow 2: performance * Climbs tall thresholds and avoids objects well * Solid job at vacuuming and mopping * Truly hands-free experience and easy-to-use app I had no issue connecting the Narwal Flow 2 to Wi-Fi or the app. The robot mapped my house in 35 minutes. I had to split and merge a few rooms, but that was simple enough. As part of my testing, I utilized the robot vacuum like anyone else might - letting it clean my entire house multiple times, directing it to specific rooms (like the kitchen after dinner), or to an area where I'd made a mess (like near my sewing machine). In doing this, I found that the vacuuming and mopping capabilities of the Narwal Flow 2 were solid. The water output was perfect, and by that, I mean my floors weren't too wet and they dried very quickly. One of my favorite aspects of this robot vacuum is the roller mop. Some brands opt for circular mop pads that spin, however, I always thought such pads just moved wet dirt and other materials around the floor before the robot had a chance to return to the base to wash the pads. The Narwal Flow 2 has a roller map that's wide (almost flattened), and as it rotates, the robot sends clean hot water to the mop so that it's cleaning the mop as it cleans your floors. A 12N downward pressure of the roller mop also aids in removing stubborn or heavy messes. If the robot vacuum recognizes a significant spill, it will also return to the base to clean the roller before returning to clean the floor again. The robot easily climbed my thresholds - some of which are two inches / 5cm high - and avoided a lot of objects. In fact, I felt like it stayed too far from objects and edges at first, so I adjusted the cleaning to 'meticulous' within the app and was happier with the results. I also watched it avoid low overhanging areas like my kitchen cabinets. At least the robot vacuum had the ability to extend the roller mop 1.8 inches / 4.6cm under the cabinet. Still, it wasn't far enough to clean fully under the cabinet, so I had to use a vacuum to reach under there. The robot vacuum got stuck once on my bath rug, which has fringe, but that was the only object that it ever has any issue with. it avoided cords and shoes, and even noted them on the map. While I could customize the suction power of the vacuum, I liked to keep it on Smart so that the suction adjusted based on the floor type and whether the robot sensed dirt or a mess. I liked that the robot vacuum used the LED light in low light areas to clean better. The Narwal Flow 2 didn't do well with suctioning large objects like medium-sized leaves from my poinsettia plants. This isn't that big of a deal as most robot vacuums (or vacuums) don't do well with suctioning larger items. Although I used the app most of the time to direct the robot vacuum, occasionally, I used one of the 34 voice commands. Sometimes I had to use the app because the commands are limited. For instance, I could tell it to clean my living room, but I couldn't say, "Clean up the living room and the hallway." Combining commands wasn't possible. The robot vacuum took three hours to clean my entire 1,600-square-foot house, dropping to 31 percent in terms of the battery. In fact, the battery was only at 50% at the 2-hour cleaning mark. It took four hours to fully charge the robot vacuum, which is quick in my opinion. Overall, I was very happy with how well Narwal Flow 2 kept my house clean of dirt, debris, and kitchen scraps. That said, after running some cleaning tests, there are some areas where it could improve. Cleaning tests To begin my testing, I placed ground coffee, flour, and dried flower petals on my kitchen laminate floor and on my living room rug and utilized the vacuum-only feature to see how well the robot could suction different materials. I even made sure to sprinkle ground coffee under my kitchen cabinets, along the edges of my kitchen, and in the corners. Here's what I observed. In the kitchen, the robot vacuum increased suction automatically when it went over the flour and the dried flowers, but not over the coffee. It suctioned all of the coffee, all but one flower petal, and most of the flour. Unfortunately, the wheels of the robot vacuum moved a thin film of the flour around on the floor. Where it didn't succeed was suctioning coffee from the corners, edges, and under the kitchen cabinet. To be fair, the robot couldn't fit under the kitchen cabinet. When it came to corners, the robot vacuum suctioned coffee completely in one corner, but not the other. It failed quite miserably with suctioning coffee grounds along the edges. As for the suction test on the rug, the robot vacuum automatically increased the suction to 'super powerful' when it recognized the material. On the first pass, the robot vacuum picked up some coffee grounds and flour but all of the dried flower petals. I also placed slightly damp poinsettia leaves on the carpet, and the robot vacuum did not pick them up but unintentionally moved them off the rug. I was disappointed at first, until the robot vacuum went over the coffee and flour three more times - without me instructing it to do so. By the end, 98 percent of coffee grounds had been suctioned. A lot of the flour had been picked up, minus a small amount that had been pushed into the rug. In the end, I thought the suctioning capability on rugs was better than most robot vacuums. For the final test, I used the vacuum and mop features on my laminate floor. I covered the floor with flour, coffee grounds, a spilled glass of water, chocolate sauce, soy sauce, wing sauce, and creamer. The Narwal Flow 2 cleaned up the wing sauce, soy sauce, water spill, coffee grounds, and flour in a single pass. I was surprised by how smoothly it picked up the chocolate sauce since it's a tough substance that dries quickly. (I test wet-dry vacuums and even many of them have issues with cleaning slightly dried chocolate sauce in two passes or more.) When it came to the creamer, the robot vacuum recognized it as a 'spill', which meant it cleaned it up in a single pass then returned to the dock to clean the mop. It then repeated this two more times -- cleaning that area and returning to the dock to clean the mop -- before it moved on. The floor was not sticky by the time the robot vacuum had finished. I also placed coffee grounds under the cabinet, in the corners, and along the edges to see if the mop and vacuum combo would result in better cleaning capabilities. When the robot vacuum passed near the cabinets, it extended the mop to the side, and while it picked up a bit, unfortunately, the roller mop couldn't extend far enough to pick up half of the coffee grounds under the cabinet When it came to corners, the robot vacuum had the same results using the vacuum and mop as it did during the suction only test. It cleaned edges better with the mop than without it, but the results weren't as good as I'd hoped. One edge was cleaned very well but a lot of coffee grounds were left along another edge. To sum it all up, I'd advise utilizing the vacuum and mop features on hard flooring to maximize the cleaning process. The Narwal Flow 2 does an average job edge and corner cleaning. When it comes to carpets, it can pick up a lot of debris, though for the finest materials like flour, you'll probably need a more powerful vacuum. Maintenance When it comes to the Narwal Flow 2 , there isn't much maintenance you'll need to do daily or weekly. It took 16 uses of the robot vacuum before I was informed to refill the water tank and empty the dirty water tank. I would suggest going through the app when you first start using the Narwal Flow 2 to set up the maintenance how you see fit. Head to the "Dock" section and choose what kind of mop drying intensity you prefer (silent, strong, or smart), as well as how often you want the dust bin to be emptied (every time of execution or when the robot determines it needs to be emptied). You can even choose the noise level of the dust emptying. The base cleans the roller with 140-degree hot water and dries it completely with hot air. The dust bag holds up to 120 days' worth of debris. In the future, Narwal may roll out a reusable dust bag. The debris filter is washable and should be cleaned once a month. You'll need to remove the bottom tray of the base and clean it out once or twice a month as lots of debris and dirt accumulates there. Within the app, you can keep an eye on which accessories need to be replaced and/or how much longer they will last. For instance, the zero-tangling floating brush on my testing robot is still good for another 144 hours of use. * Performance score: 4/ 5 Narwal Flow 2: app * Easy app with fantastic 2D and 3D mapping and insights * Cleaning customization options (AI clean, vacuum and mop, vacuum then mop, vacuum, mop, and room customization) * Video features and control through app I had an easy time using the Narwal app to set up the Narwal Flow 2 . Although there is a 3D mapping option, I preferred using the 2D option and had an easy time labeling the rooms and seeing things like rugs on the map. I ran into some issues trying to split my living room and study on the map. The rooms have a wide doorway with pocket doors, so I understand the robot thinking they are the same room, but when trying to split them, the map says in doing so the rooms are "too small." This is odd considering that my bathroom is about a sixth the size of each of those rooms and it was considered its own room on the map. I tried to set up my corridor as a no-go zone (the floors are not sealed and can't be mopped), but unfortunately, when I did this, the robot vacuum wouldn't pass the corridor to clean the bathroom. Thankfully I was able to go around this with the room customization feature which allows me to customize the type of cleaning I want for each room. Therefore, I designed the corridor to be a vacuum-only space so that the robot vacuum would be able to reach the bathroom where I have it designated to be vacuumed and mopped. Within the app, I can choose to clean the whole house, certain rooms, or even specific zones within those rooms. I can also customize this further by informing the robot vacuum to vacuum and mop, vacuum then mop, vacuum only, or mop only. One of my favorite features is the Navo assistant that sits below the map offering insight on the cleaning or information that's relevant, like if the vacuum has gotten stuck. If you click it, the assistant shows you the voice commands that you can use with the robot vacuum and lets you adjust the language and voice tone. The Dock button informs users of the dust bag status and touch-on-demand features like dock dust emptying, dust bag dry and disinfecting, mop washing, mop drying, and adjusting the ambient lighting effects. Users can watch a live video from the cameras on the Narwal Flow 2 . You can record or take videos, control the direction of the robot, and direct the robot to clean. There is also a Cruise feature that takes photos on a specific route through your house and stores them in the app. On top of scheduling cleanings and monitoring the cleaning history, you can also adjust the cleaning settings, from the suction power to the mopping humidity, coverage precision (smart, standard, and meticulous), and set things like intensive corner cleaning, priority cleaning for carpet, intensive carpet cleaning, intelligent room splitting and rewashing of the mop, high altitude mode, child lock, do not disturb feature, obstacle avoidance strategy, and smart object detection. It's also here where you can set up your Narwal Flow 2 with Alexa, Google Home, or Matter. The Pet-friendly Mode section is very extensive. Users choose which pets they have (cats, dogs, or both) and designate either easy cleaning in specific pet areas or enhanced cleaning in areas that were missed because pets were present. It also allows you to find your pet and/or "play" with your pet by attracting the pet to the robot with a specific sound. * App score: 4.5/5 Narwal Flow 2: specs Narwal Flow 2: should you buy it? Buy it if Don't buy it if Narwal Flow 2: also consider If you're not sure whether the Narwal Flow 2 is the right robot vacuum for you, here are two other options to think about. How I tested the Narwal Flow 2 I tested the Narwal Flow 2 for two weeks on my laminate and historic wood floors and medium-to-large pile rugs. To review all the vacuuming and mopping capabilities, I conducted several tests with various materials (water, chocolate syrup, soy sauce, coffee grounds, and flour) on different types of flooring to see how well the robot suctioned and cleaned the floor. This included testing different features like spot cleaning, video capabilities, mapping, voice commands, and so much more. Read more about how we test
