Qrevo CurvX
2 independent reviewsRead the findings →A very slim Roborock whose laser turret drops down to get under low sofas and beds. It's strong on navigation and hard floors in a reasonably tidy home. Its tiny onboard bin can't cope with a heavily shedding dog.

What reviewers found
Two lab-style tests and one long home test. Vacuum Wars measured strong carpet deep cleaning, no hair tangles and an above-average obstacle score, and TechGearLab ranked it first of 23 robots for navigation, hard floors and ease of use. Both found pet hair a weak spot, in different ways. Clutter is the big disagreement: the same outlet's three-month home test, Vacuum Wars (home test), found it tried to climb over toys and cables and needed rescuing far more often than the studio results suggest.
Vacuum Wars, hands-on, Several weeks · TechGearLab, hands-on, Mar 2026 · Vacuum Wars (home test), hands-on, About 3 months at home (Tested in a 750 sq ft family home with a heavy-shedding dog; Additional testing from an outlet already counted here; its findings are included without counting another independent outlet.)
Hard floors
Reviewers rate it highlyTechGearLab found it excelled on hard floors, picking up nearly all its cereal and most rice, with edge cleaning one tester called the best they'd seen. Vacuum Wars found its two brushes worked very well together on hard floors.
Carpet and rugs
Reviewers rate it highlyVacuum Wars measured embedded-sand removal from medium carpet among the very best it has tested. TechGearLab found carpets noticeably cleaner, with neat methodical passes, though some deeply embedded sand stayed in thicker pile.
Pet hair
Mixed resultsVacuum Wars found no hair tangles, but warns the very small robot bin means frequent runs in homes with pets. TechGearLab rated pet hair its weakest area, with fur balling on the roller and some needing to be cut free.
Mopping
Reviewers rate it highlyVacuum Wars found the mopping strong and reliable, though it uses more than double the average water even on the lowest setting. TechGearLab saw dried coffee and wet spills handled, leaving floors mostly dry.
Navigation and obstacles
Mixed resultsVacuum Wars and TechGearLab reported strong obstacle avoidance in controlled tests. In three months at home, Vacuum Wars (home test) repeatedly had to rescue it from toys, cables and cloths. Clear those hazards before a run, even though the shorter tests were encouraging.
Dock and upkeep
Mixed resultsVacuum Wars and TechGearLab praised the dock's automation, but Vacuum Wars (home test) found dog hair blocking the bin and emptying channel. It saves routine emptying work, yet a shedding-pet home may still need frequent checks and manual clearing.
App and software
Reviewers rate it highlyVacuum Wars rates the Roborock app one of the best for usability, and TechGearLab found it approachable even for first-time owners, with detailed maps, object icons and remote camera viewing.
Noise
Not enough evidenceOnly TechGearLab measured it, at 56.3dB on standard suction and 64.4dB while auto-emptying, both on the quiet side of the robots it compared.
Reliability and support
Not enough evidenceVacuum Wars (home test) used it for about three months and reported frequent hair clogs and rescues, but that's a second test from an outlet already counted here. Vacuum Wars separately rated Roborock support highly. No other outlet has backed up either long-term reliability or support yet.
Value
Not enough evidenceOnly TechGearLab judged value, calling it absolutely worth it if the high price fits your budget, while pointing to cheaper robots that still clean well.
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
Careful in the lab, bolder at home
Vacuum Wars scored it 20 out of 24 for obstacle avoidance, against an average of 17. TechGearLab saw it avoid 88% of set obstacles, including cords, shoes and simulated pet waste. In a family home with three children and a big dog, Vacuum Wars (home test) had a different experience: it often tried to climb over toys, cables, tissues and washcloths, sometimes losing a mop pad, and it bumped repeatedly into the dog when she lay still. Treat the lab scores as a best case and tidy up first.
Tiny bin, big problem with hair
In a home with a shedding dog, Vacuum Wars (home test) had near-daily bin clogs and the occasional clump of hair spat back onto the floor. Emptying between rooms helped. TechGearLab also found fur gathered on the roller, with some needing to be cut free, while Vacuum Wars found no tangles in its studio test. So with a hairy pet, expect to check both the bin and the brush.
Strong on carpet, spotless edges
Vacuum Wars recorded 92% of embedded sand removed from medium carpet, tied for third of more than 205 robots. TechGearLab measured about 79% of carpet debris and said deeply embedded sand remained in thicker pile. On hard floors TechGearLab was more enthusiastic, praising edge cleaning so thorough that one tester called it the only robot they'd seen clean the full length of a wall. TechGearLab also liked its tight, methodical passes, which left neat lines in the carpet.
Mops well once set up right
Vacuum Wars measured high water output even on the lowest setting, more than double the average, but saw no streaks on dark floors in follow-up runs. TechGearLab found it dealt with dried coffee and wet spills and left floors mostly dry. Vacuum Wars (home test) got streaks and gritty floors from tracked-in clay at first, then switched to vacuuming first and mopping afterwards. That fixed it but roughly doubled cleaning time. Pads came back fresh and odour-free throughout.
Slips under very low furniture
Vacuum Wars notes it's tied for the lowest robot it has measured, about an inch shorter than average, thanks to the turret that drops down under furniture. TechGearLab measured 3.2 inches. In daily use Vacuum Wars (home test) found it got deep under beds, even beneath overhanging blankets, and navigated well at night with its built-in light. If your sofa gap is around 8cm, this is one of the few robots with a laser turret that fits.
Vacuum Wars published a studio review and a three-month home test by a different tester. Both inform this profile; together they count as one independent outlet.
Our take
Should you buy the Qrevo CurvX?
Best for: Homes with low sofas and beds to clean underneath. Skip it if: You have a pet that sheds heavily or lots of long hair.
buy it for low sofas and beds, mostly hard floors and a reasonably tidy home, but skip it with a heavy-shedding dog. The Saros 10R is also low enough for most furniture, and the original Qrevo Curv covers more floor per charge if height doesn't matter.
The Qrevo CurvX follows the original Qrevo Curv with a sensor on top that retracts when it senses furniture above, so the robot is just under 8cm tall. Roborock added a chassis that lifts over doorway thresholds, a split main brush to stop hair wrapping and a dock that washes the two spinning pads in hot water and dries them. The bin inside the robot is very small.
Both lab-style tests rate it highly. Vacuum Wars measured embedded-sand removal from carpet among the very best it has tested, with no hair tangles, and TechGearLab ranked it first for navigation, hard floors and ease of use, with edge cleaning one tester called the best they'd seen. TechGearLab did see fur ball on the roller and rated pet hair its weakest area. The long home test is where the problems showed up. Over three months with a heavy-shedding dog, Vacuum Wars found the bin clogged almost daily, sometimes spitting hair back onto the floor, and hair blocked the dock's emptying channel. It also tried to climb toys and cables far more often than the studio scores suggest. Vacuum Wars measured mopping water at more than double the average even on the lowest setting.
Before you buy
The questions people ask about this one
Will it avoid cables and pet mess?
In lab tests, mostly yes: TechGearLab saw it avoid simulated pet waste and 88% of set obstacles. At home, Vacuum Wars (home test) had it try to climb cables, toys and cloths, and it bumped a sleeping dog even on the highest sensitivity. Don't leave cables or accidents on the floor.
Does it fit under low furniture?
Probably. It's 7.98cm tall with the turret lowered, per the specifications, and TechGearLab measured 3.2 inches. Vacuum Wars (home test) found it reached deep under beds. Measure your lowest gap before buying, since the turret has to retract to get under.
How often do I have to empty or refill anything?
Vacuum Wars (home test) had to deal with the water tanks often, and sometimes emptied the robot's bin by hand because of dog hair. The tester also saw dust leak from one particular third-party bag. Use bags made to fit this dock and check the seal. That one example doesn't tell you how every replacement brand performs.
Can it cross rugs and raised thresholds between rooms?
Roborock claims its lifting chassis crosses double-layer thresholds up to 4cm, per the specifications. Vacuum Wars says it did well crossing thresholds in its tests. TechGearLab found it didn't chew up thin washable rugs, which trips up many robots.
How big is the dock, and is it loud?
The dock is a 45cm cube according to the specifications, and the robot parks underneath it like a garage. TechGearLab measured 56.3dB while vacuuming on standard power and 64.4dB during auto-emptying, both on the quiet side among the robots it compared.
Alternatives
Other robot vacuums to compare.
Saros 10R
Why consider it: Also under 8cm tall, and lab tests found it superb on hard floors and one of the best at dodging clutter.
The compromise: Pet hair buried in carpet is its weak spot too.
Qrevo Curv 2 Pro
Why consider it: Reviewers rate its carpet cleaning among the best, and it slides under low furniture.
The compromise: Its spinning pads smear sticky spills and it runs over small objects.
Qrevo Curv
Why consider it: Superb on hard floors, great at mopping and good at climbing doorway thresholds.
The compromise: It's about 10.4cm tall and misses too many small objects.
Qrevo CurvX head to head
Head to head
Roborock Qrevo Curv vs Qrevo CurvX
Our verdict: The CurvX is about 2.5cm lower and scored better on obstacles in Vacuum Wars's test. The original Curv covered more floor per charge and pulled more air in the same tests. Pick the CurvX for low furniture, the Curv if height doesn't matter.
