I tried the Roborock Qrevo Curv 2 Flow: It's cracked the code to roller mopping along edges
Table of Contents
Out of the 25+ robot vacuum and mop combos that I've tested, only a few were roller mop robot vacuums. The verdict? I wasn't a roller mop non-believer, but I wasn't exactly a believer, either. While they excelled at sopping up large wet spills, both the Dreame Aqua10 Ultra Roller and Eufy E28 had me doubting how closely a large roller mop could really scrub near a wall. But when the Roborock Qrevo Curv 2 Flow was announced, my ears perked up. Roborock was responsible for two of my most recommended robot vacuums of the past few years, specifically for their corner scrubbing abilities — so if any brand could perfect roller edge mopping, it's Roborock.
What's special about the Qrevo Curv 2 Flow?
Roborock announced three new robot vacuums at CES 2026. Two of those are successors to the flagship Saros robot vacuums that were a huge deal last year, making it easy for the Qrevo Curv 2 Flow to get lost in the shuffle. I can't say that the name helps it stand out, either: There are too many Roborocks in the Qrevo line for the average person to keep track of. And past Qrevo Curv models weren't all that different from Roborock's other existing flagships — other than their sleek, curved self-empty docks, obviously.
So "Qrevo Curv 2 Flow" definitely doesn't encompass how this model is not only different from Curvs past, but different from any mopping Roborock we've seen: It's Roborock's very first robot vacuum with a roller mop.

Its 20,000 Pa suction power feels pretty appropriate for its $999.99 MSRP. That 20,000 Pa sounds even better at $849.99, the Curv 2 Flow's consistent sale price since it came out at the end of January.
For reference, Roborock's 2025 trifecta — the Saros 10, Saros 10R, and Saros Z70 with the grabby arm — are negligibly stronger at 22,000 Pa, and they were all at least $500 more than the Qrevo Curv 2 Flow upon release. The roller mop Eufy E28 offers the same 20,000 Pa and also costs $999.99, and the Dreame Aqua10 Ultra Roller with 30,000 Pa costs $1,599.99 (though it's been discounted a lot recently).
Is the Qrevo Curv 2 Flow good on carpet?
The Curv 2 Flow has handily tackled debris on medium-pile and thick rugs. As I did when testing the Dreame X60 Max Ultra Complete, I dumped sprinkles onto my fluffy hallway rug and tangled a handful of cat hair clumps through the fur. Though the Dreame vacuum is significantly stronger with 35,000 Pa of suction power, I honestly think that the Curv 2 Flow did just as good a job — the pickup rate of both was almost perfect. When I got down on eye level to see if the Curv 2 Flow cleaned up crushed chips on my tufted living room rug, it was spotless aside from a single long hair.
Perhaps you were so distracted by this glorious S-shaped cleaning path to notice the USB-C cable in the top left corner. And nope, it didn't get eaten. The Curv 2 Flow's small obstacle recognition cameras quickly identified it in the app, and I watched the botvac safely swerve around the charger without running it over. In other cleaning runs, a longer iPhone charger and an extension cord for a lamp were also marked safe. That's more consistent cord avoidance than I've experienced with any other flagship in the past year. A small fabric cat toy that looks like a sloth was recognized as pet waste. I'll take it.
The Curv 2 Flow occasionally left a bit of debris around the outskirts of rugs, especially my cushioned kitchen Ruggable that has a pretty substantial flap around the edges. But that's the case with every robot vacuum I test, no matter how premium. That said, the Qrevo Curv 2 doesn't struggle at all to transition from hard floors onto those rugs. The AdaptiLift chassis essentially features a pair of legs. They're not going to climb anything higher than a few inches, but it's a really great feature to ensure smooth transitions onto plush carpet or between floor type changes in doorways.
Is the Qrevo Curv 2 Flow good at mopping?
I've been pleasantly surprised with the flexibility of the Curv 2 Flow's SpiraFlow roller mop — for the most part, it isn't literally cutting corners as I expected. The roller sits in a sliding case that visibly extends an inch or two past the vacuum's circumference when an edge is sensed. The Curv 2 Flow has provided an extremely close scrub against walls, including the wall of my bathtub, where there are always tiny pieces of hair and kitty litter dust stuck in dried soap droplets.
I appreciated the roller's precision when circling around a fully upholstered velvet armchair. My cat loves batting stuff under that specific chair, constantly pushing any nearby dust, hair, and catnip particles right under the outer edge. I'm also pretty sure I watched it mop around my cat, Sansa's tail without touching her.
So far, the Qrevo Curv 2 Flow's roller mop has thoroughly scrubbed a variety of liquid messes on hardwood in my kitchen and tile in my bathroom. These ranged from super watery spills like red wine and orange juice to thicker, stickier consistencies like globs of queso, drops of body lotion, and Chick-fil-A Sauce. The wet roller also did a phenomenal job of wiping up super fine powder that suction power and a side brush alone will miss, like kitty litter dust, protein powder, and general dust that accumulates day to day.
The main advantage of a roller mop is the ability to prevent smearing across the rest of the floor, whether that's dirty water or a trail of the sauce it was supposed to be cleaning up. First, the long fibers on a roller mop are highly absorbent — much more similar to a fluffy bath towel than a microfiber cloth, like what most rotating mops use. Roller mops are just a sturdier design than thin spinning mops in general, able to exert stronger downward pressure. As they're scrubbing with extra elbow grease, most roller mops self-rinse to ensure every part of the floor is being cleaned with fresh water.
The Qrevo Curv 2 Flow only mildly struggled with smearing once. To be fair, it was purposefully a lot of queso to wipe up in one try — I was literally just spooning globs out onto the floor for extreme testing purposes. If I spilled that much in real life, I'd definitely go in with a paper towel first to get the worst of it, then send the robot in to sanitize and tackle any remaining stickiness.
The hardwood was pretty much spotless after I sent the Curv 2 Flow back for a second time. If you've ever tested the mopping capabilities of a super cheap robot mop, you can imagine how ugly this would get.
The dock does not have an automatic detergent dispenser, so you'll have to manually squirt your cleaning solution of choice into the water tank when you fill it up. I'm not that upset about it for a vac under $1,000. If you're sending it after anything oil-based, I'd make sure to put extra detergent in the tank.
Factors I'm keeping an eye on: Nimbleness in tight spaces
The Roborock Qrevo Curv 2 Flow definitely isn't a slim robot vacuum. It measures 4.7 inches tall, just like the Dreame Aqua10 Ultra Roller.
Both simply require a taller vacuum chassis to house the large roller mop and threshold climbing legs. But the Aqua10 Ultra Roller can squeeze under four inches when its retractable LiDAR tower is down, while the Curv 2 Flow's LiDAR tower is always up. You'll want to consider compactness if your home has low-hanging cabinets or low-clearance furniture to clean under.
I do feel like the roller mop prematurely rescinds near some 90-degree angles where the Curv 2 Flow can tell that it needs to change direction soon, like approaching the side of the refrigerator that sticks out further than the cabinets. If a spill is tucked too far into a corner, a smidge of it will probably need to be wiped up by hand. That might get old if you live in a small space.
