Quick Answer: The Roborock Qrevo Curv 2 Flow is a genuinely strong vacuum wearing a disappointing mop. Vacuum Wars measured a perfect 0% hair-tangle score and 87% carpet sand removal (vs a 76.7% average) — flagship-grade cleaning. But its SpiraFlow roller mop scored just 25-38 points on the dried-stain test against a 112-point average, one of the weakest mopping results recorded on a 2026 flagship. It launched at $999.99 and already sells for $899.99 per Roborock’s own store. Buy it if vacuuming is the priority; skip it if mopping matters as much as vacuuming, and look at the original Qrevo Curv or the CurvX instead.
The original Roborock Qrevo Curv held Vacuum Wars’ #1 overall ranking for the better part of two years by being excellent at both halves of the job — vacuuming and mopping. The Qrevo Curv 2 Flow is its roller-mop successor, and it makes a clear trade: sharper vacuuming numbers in exchange for a mop that, per independent testing, is a step backward from the model it replaces.
Roborock Qrevo Curv 2 Flow by the numbers
- 0% hair tangle in Vacuum Wars’ tangle test — a perfect score, tying the DuoDivide brush design used across Roborock’s current lineup.
- 87% carpet sand removal, above the site’s 76.7% average, despite a below-average measured sealed suction of 0.47 kPa against a 0.97 kPa average.
- 25-38 points on the dried-stain mopping test (medium vs maximum water setting) against a 112-point average — among the lowest mopping scores Vacuum Wars has recorded on a current-gen flagship.
- 270mm SpiraFlow roller mop with 15N of downward pressure and real-time fresh-water self-cleaning, auto-lifting 15mm on carpet.
- 16 of 24 objects avoided in obstacle testing — right at the site’s 16.6 average — using structured light plus an RGB camera Roborock says recognizes over 200 clutter types.
- $999.99 list, $899.99 current price per Roborock’s own US store — already discounted at launch.

Roborock Qrevo Curv 2 Flow
- Perfect 0% hair-tangle score and 87% carpet sand removal, per Vacuum Wars — ahead of the field on raw cleaning.
- SpiraFlow roller mop washes itself in real time with fresh water, but underperforms on dried, stubborn stains.
- Dock heats wash water to 167°F and dries at 131°F, with disposable-bag auto-empty.

Vacuuming: where the Curv 2 Flow earns its price
The headline number is the 0% hair tangle — a perfect score matching the best result Vacuum Wars has recorded, thanks to the DuoDivide brush design Roborock has carried across its 2026 lineup. Carpet performance backs it up: 87% sand removal, comfortably above the site’s 76.7% average.
That’s despite a measured sealed suction of just 0.47 kPa, below the 0.97 kPa average and well under Roborock’s advertised 20,000 Pa headline. It’s the same pattern we’ve flagged on other 2026 flagships — see the Roomba Max 705 review — where the claimed Pascal figure and independently measured sealed suction diverge. Here the real-world carpet result held up anyway; pet-hair pickup landed closer to the field at 77.5% against an 81% average.
Mopping: the trade Roborock made
This is the part of the review that should change your buying decision. The SpiraFlow roller mop is a genuine engineering shift from the spinning pads on the original Qrevo Curv — a 270mm roller washed with real-time fresh water under 15N of downward pressure, auto-lifting 15mm on carpet.
On Vacuum Wars’ dried-stain test, though, it scored just 25 points at a medium water setting and 38 at maximum — against a 112-point average across tested robots, and far below the 163 the Qrevo CurvX posted on a comparable coffee-stain test. Water residue left behind was very low (0.2g vs a 1.04g average), so the roller isn’t over-wetting floors — it’s simply not lifting dried, stuck-on messes as effectively as the spinning-pad docks Roborock still sells. If your floors mostly need fresh spills wiped up, this won’t matter much day to day. If you’re dealing with dried, stubborn stains regularly, the gap is real.
What we don’t like
- Dried-stain mopping score of 25-38 against a 112-point average — one of the weakest results on a current-gen flagship.
- Measured sealed suction (0.47 kPa) well below the 0.97 kPa average, despite the 20,000 Pa marketing figure.
- Obstacle avoidance (16/24) lands exactly at the field average rather than ahead of it.
- Pet-hair pickup (77.5%) trails the 81% average, a smaller but real gap for shedding-pet homes.
How it compares
Inside Roborock’s own Curv family, the choice comes down to what you value more. The original Qrevo Curv held Vacuum Wars’ #1 overall ranking for most of two years on the strength of balanced performance — its 104-point dried-stain score dwarfs the Curv 2 Flow’s 25-38 — and now sells for around $1,099.99. The CurvX sits between the two on price at $1,199.99 and posted a much stronger 163-point coffee-stain result. The Curv 2 Flow’s case is narrower: buy it specifically for the vacuuming numbers, not as a do-everything flagship.
Against the wider field, the Curv 2 Flow’s perfect hair-tangle score and strong carpet result put it ahead of most 2026 launches on raw vacuuming — see our best robot vacuum and best robot vacuum for pet hair rankings for how it stacks against Dreame, eufy, and Shark flagships. For mopping specifically, our best robot mop guide leans toward the pad-based docks this generation trails.
Who should buy the Roborock Qrevo Curv 2 Flow
- Buy it if vacuuming — carpet cleaning and pet hair in particular — is your top priority and mopping is a bonus feature, not the main job.
- Buy it if you mostly need fresh spills wiped rather than dried, stuck-on stains lifted; the low water residue means it won’t leave floors soggy.
- Skip it if mopping performance matters as much as vacuuming — the original Qrevo Curv or the CurvX post far stronger dried-stain scores.
- Skip it if you’re a shedding-pet household chasing the best possible pickup number; 77.5% is solid but not flagship-leading.
The bottom line
The Qrevo Curv 2 Flow is a reminder that a flagship name doesn’t guarantee flagship results in every category. Its 0% hair tangle and 87% carpet sand removal are genuinely excellent, and at $899.99 it undercuts the original Curv’s current price. But the 25-38 point dried-stain mopping score is a real step down from the 104 the original Curv posted, and it’s not close. If you’re buying primarily for vacuuming, this is a strong pick. If you want one robot that mops as well as it vacuums, the original Qrevo Curv remains the more complete machine. Start with our best robot vacuum rankings if you’re still comparing options.
