Qrevo Curv
3 independent reviewsRead the findings →Roborock's former Qrevo flagship, the first with a body that lifts itself over door thresholds. It's superb on hard floors and great at mopping. It misses too many small objects, so clear the floor first.

What reviewers found
Three tests of the original Curv. RTINGS ran it through its lab, TechRadar used it at home with five pets, and Vacuum Wars put it through its studio tests, where it briefly topped the rankings. All three rate the hard-floor cleaning and mopping highly. They split on carpet and pet hair, and on obstacles, where RTINGS was the harshest. None of these tests covers the Curv 2 models or the CurvX.
RTINGS, lab test · TechRadar, hands-on, Nov 2024 · Vacuum Wars, lab test, Nov 2024
Hard floors
Reviewers rate it highlyRTINGS rated its hard-floor pickup among the best it has seen, with the pop-out side brush clearing edges, and TechRadar saw every oat flake collected. Vacuum Wars found exceptional pickup, though heavy debris got spread sideways first in its extreme test.
Carpet and rugs
Mixed resultsVacuum Wars measured embedded-sand removal among the best it has tested, and TechRadar saw it cope with very deep carpet. RTINGS found it struggles with fine debris in carpet, because the rubber rollers don't agitate the pile much.
Pet hair
Mixed resultsVacuum Wars recorded zero hair tangles and strong pickup of flattened pet hair, and TechRadar had no trouble in a home with five pets. RTINGS found hair buried in carpet fibres hard for it to lift.
Mopping
Reviewers rate it highlyRTINGS called its mopping among the best there is and great on dried stains, and Vacuum Wars scored it highly on dried stains too. TechRadar needed a couple of passes for dried soy sauce but saw a clear daily difference.
Navigation and obstacles
Mixed resultsTechRadar found it crossed rugs and a book-stack threshold without trouble, but it rode over phone cables. RTINGS found it missed cords and socks and bumped into pet waste, and Vacuum Wars rated avoidance reasonable but not perfect.
Dock and upkeep
Reviewers rate it highlyVacuum Wars found upkeep efficiently automated, and TechRadar had no trouble with the dock emptying heavy pet hair. The 2.7-litre bag is small, though: TechRadar changed it every three weeks with five pets.
App and software
Reviewers rate it highlyVacuum Wars rates Roborock's app arguably the best in the industry, easy to use with deep control. TechRadar found it smooth and comprehensive, though its many settings take time to learn.
Noise
Not enough evidenceOnly TechRadar commented, finding it fairly quiet at around 60dB in standard mode. Nobody else has judged the noise yet.
Reliability and support
Not enough evidenceNone of the reviews we use has run it long-term or judged Roborock's support yet.
Value
Reviewers rate it highlyVacuum Wars found it better value than other flagships for its performance, and TechRadar thought it not bad value given the build and smarts, especially on discount, while noting cheaper robots suit many homes.
Verdicts come from independent, hands-on, finished reviews. An area needs at least two of them before we say more than “Not enough evidence”. We don't score robots ourselves. How this works
Excellent on hard floors and edges
RTINGS rated its hard-floor pickup among the best it has seen, with the pop-out side brush clearing edges and corners. Every oat flake was collected in TechRadar's test, none flung about. Vacuum Wars also found exceptional pickup on hard floors, though in its heavy-debris torture test the side brush spread mess sideways before collecting it. For everyday kitchen crumbs, it's hard to fault.
Carpet and hair: testers disagree
Vacuum Wars placed its embedded-sand result sixth among more than 100 robots tested and found no hair wrapped round the brush. TechRadar also liked its carpet cleaning. RTINGS was less keen, finding fine dirt and embedded hair left in the pile. If carpet or pet hair is your main job, it's a less sure bet than it is on hard floors.
A strong mopper
RTINGS and Vacuum Wars both reported strong stain removal. TechRadar needed a couple of passes for dried soy sauce but saw a clear improvement on its kitchen floor in daily use. The mop pads lift over carpet, but thick pile may still touch them, so check the carpet settings before a combined vacuum-and-mop run.
Climbs doorway thresholds and rugs well
TechRadar watched it scale a stack of books like an off-road vehicle and cross all its loose rugs without rucking them up. Vacuum Wars saw it struggle with a 25mm threshold at first, then get over once the threshold was marked in the app. RTINGS noted patchy manoeuvring on carpet. During setup, mark your tallest step in the app.
Clear the floor first
RTINGS found its obstacle handling disappointing: it didn't consistently recognise cords or socks, and bumped into shoes and even pet waste. TechRadar saw it dodge most things taller than about two inches but ride over phone cables, and wouldn't trust it near dog mess. Vacuum Wars rated avoidance reasonable but not perfect. That's the main reason to tidy before every run.

Our take
Should you buy the Qrevo Curv?
Best for: Homes where raised door thresholds strand other robots. Skip it if: You have low furniture or need strong pet hair pickup on carpet.
Consider the Qrevo Curv for mainly hard floors and raised thresholds, provided you clear small hazards before each run. Carpet and pet-hair results differed between reviewers. If you also need to reach under low furniture, compare body height and tested clearance separately from cleaning performance.
The Qrevo Curv topped Roborock's Qrevo line when it launched, and it was the first Roborock with a chassis that lifts itself over doorway thresholds. It mops with two spinning pads, one swinging out to skirting boards, and the dock washes them in hot water and dries them with warm air. With a raised sensor that cannot lower it stands about 10.4cm tall, so it won't get under low sofas the way the newer Curv 2 Pro does. It's now thin on the ground in some countries.
All three reviewers praised hard-floor pickup and mopping. RTINGS found particularly strong hard-floor cleaning, TechRadar collected all of its oat flakes, and Vacuum Wars also reported excellent pickup. Dried soy sauce needed a second pass in TechRadar’s mopping test. Carpet results were less consistent. Vacuum Wars measured strong embedded-sand removal and no brush tangles, while RTINGS found fine dirt and buried hair left behind. Small hazards are another weakness: tests recorded missed cables, socks and simulated pet waste. In TechRadar’s busy pet household, the dust bag needed changing about every three weeks.
Before you buy
The questions people ask about this one
Will it avoid cables and pet mess?
Not reliably. RTINGS saw it miss cords and socks and bump into pet waste, and TechRadar found it rode over phone cables and wouldn't trust it near dog mess. Pick things up before each run.
Does it fit under low furniture?
Only moderately low furniture. Because of the laser turret, Roborock lists the robot at 4.1 inches (about 10.4cm) tall, per the specifications. RTINGS found its tall profile keeps it out from under some furniture, so measure your lowest gap first.
Can it cross rugs and raised thresholds between rooms?
Very well for its age. TechRadar found it crossed loose rugs without rucking them and climbed a book-stack threshold. Vacuum Wars had to mark a 25mm threshold in the app before it crossed reliably. Roborock claims 3cm single and 4cm double steps, per the specifications.
How often do I have to empty or refill anything?
The dust bag is rated for up to seven weeks, but TechRadar, with five hairy pets, changed it every three weeks. You'll refill the clean-water tank and empty the dirty one, and RTINGS warns many parts wear out and need replacing.
How much space does the dock need, and how noisy is it?
The dock is roughly 45cm in each direction, before you leave space for docking and getting at the tanks. TechRadar measured the robot at around 60dB in standard cleaning mode, but that's the robot cleaning, so the reviews don't tell you how loud the dock is when it empties, washes or dries.
Alternatives
Other robot vacuums to compare.
Qrevo Curv 2 Pro
Why consider it: Its successor is praised for strong vacuuming on carpet and for sliding under low furniture.
The compromise: Home reviewers were cooler on its mopping and on how it handles small objects.
Saros 10R
Why consider it: Lab tests found excellent hard-floor pickup, strong mopping, very dependable obstacle avoidance and a much lower body.
The compromise: TechRadar found it couldn't climb the book-stack threshold the Curv handled, and a lab test found it leaves embedded pet hair behind.
Saros 10
Why consider it: Home testers praise its dog-hair pickup and its pop-down turret for low furniture.
The compromise: Its vibrating mop did poorly on dried stains in Vacuum Wars' test.
Omni S2
Why consider it: Strong carpet and hair pickup and a perfect obstacle score in Vacuum Wars' test.
The compromise: Its roller mop results are divided, and one reviewer's unit failed after a month.
