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.

What’s special about the Narwal Flow 2?

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).

The Narwal Flow 2 might have the best AI mess detection I’ve seen

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.

Is the Narwal Flow 2 good at mopping?

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.

Is the Narwal Flow 2 good at vacuuming?

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.

Factors to keep in mind

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.
