Qrevo CurvX
A very slim Roborock with a laser turret that drops down under low furniture. Lab tests rate its navigation and hard-floor cleaning highly, but its tiny onboard bin struggles in a home with a heavily shedding dog.
See the alternatives below, or switch market.
The short version
The Qrevo CurvX follows the original Qrevo Curv and keeps its rounded dock, but the robot is much lower. The laser turret on top retracts when it senses furniture above, so the whole robot is just under 8cm tall. Roborock also added a chassis that lifts itself over door bars, more claimed suction, a split main brush to stop hair wrapping, and a dock that washes the mop pads in hot water and dries them.
The trade-off comes with the slim body. The bin inside the robot is very small, and one long-term tester found it clogging almost daily with dog hair. It also uses a lot of water when mopping, so you'll refill the dock's tank more often than with some rivals. Both lab testers were impressed by how it dodged cables and clutter, but the same outlet's home test found it much less careful in a busy family house.
Our take: Buy it if you have low sofas and beds, mostly hard floors and a reasonably tidy home, and you want a robot that looks after its own mop pads. Skip it if you have a heavy-shedding dog: the tiny bin and hair clogs meant regular hands-on work in one long test. 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.
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. The sharpest disagreement is over clutter: 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.

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
The low body costs bin space. Vacuum Wars (home test) measured it at just under 260ml, and with a shedding Shepherd-Pyrenees mix it clogged almost every day, sometimes spitting rolled-up hair back onto the floor. Hair also blocked the dock's emptying channel. A custom routine that sent it to empty between rooms helped. TechGearLab also rated pet hair its weakest area, with fur balling on the roller and some needing to be cut free. Vacuum Wars found no hair tangles at all, so the problem is volume, not wrapping.
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) initially got streaks and gritty floors from tracked-in clay, then switched to vacuuming first and mopping afterwards, which 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 two separate tests: a studio review and a three-month home test by a different tester. Only the studio review counts towards the page's evidence.
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?
More often than you might expect. Vacuum Wars (home test) refilled and emptied the dock's water tanks more than planned because it mops with a lot of water, and had to empty the small robot bin by hand in a home with a shedding dog. Use official bags too: cheap third-party ones leaked dust into the dock.
How does it handle rugs and door bars?
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.

Head to head
Roborock Qrevo Curv vs Qrevo CurvX
Our verdict: The CurvX is about 2.5cm lower and scored better on obstacles in [[vacuumwars]]'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.
Saros 10R
Also under 8cm tall, and lab tests found it superb on hard floors and one of the best at dodging clutter.
Pet hair buried in carpet is its weak spot too.
Qrevo Curv 2 Pro
Reviewers rate its carpet cleaning among the best, and it slides under low furniture.
Its spinning pads smear sticky spills and it runs over small objects.
Qrevo Curv
Superb on hard floors, great at mopping and good at climbing door bars.
It's about 10.4cm tall and misses too many small objects.
