Qrevo Curv vs Qrevo CurvX

Buy the Qrevo CurvX for most homes: it's about 2.5cm lower, so it gets under sofas the Curv can't, and it avoided more obstacles in the same lab. Pick the original Curv if you have a heavily shedding dog, because the CurvX's tiny bin clogged almost daily in one long home test.

Updated

The short version

Qrevo Curv

The original, from 2024. Every test rated its hard floors and mopping highly, with one lab putting its mopping among the best it had seen, and its chassis lifts over doorway thresholds. What you give up: its laser turret doesn't drop down, so at about 10.4cm it won't fit under low sofas, and it missed cables, socks and even pet waste in the lab.

Qrevo CurvXOur pick

The slimmer follow-up. Its turret sinks into the body so it's just under 8cm tall, one of the lowest robots Vacuum Wars has measured, and it avoided 20 of 24 obstacles against the Curv's 17. Carpet cleaning matched the Curv in the same lab. What you give up: its onboard bin is tiny, and in three months with a shedding dog it clogged almost daily and tried to climb toys and cables.

What reviewers found

Qrevo Curv

Three tests agree on hard floors and mopping. RTINGS rated its hard-floor pickup among the best it has seen and called its mopping great on dried stains, and TechRadar collected every oat flake in a home with five pets. Carpet hair splits them: Vacuum Wars measured strong carpet cleaning and zero tangles, while RTINGS found buried hair hard for it to lift. RTINGS also found its obstacle handling disappointing.

Qrevo CurvX

The lab-style tests are glowing. Vacuum Wars measured 92% of embedded sand removed from carpet and no hair tangles, and TechGearLab ranked it first of its group for navigation and hard floors, with edge cleaning one tester called the best they'd seen. The long home test is harsher: Vacuum Wars found the bin clogged almost daily with dog hair and had to rescue it from toys, cables and cloths.

Where they differ

  1. 01

    Height: the CurvX gets under far more sofas

    The CurvX's laser turret drops into the body when it senses furniture, so it's 7.98cm tall at its lowest. Vacuum Wars says that ties for the lowest robot it has measured, and Vacuum Wars found it got deep under beds. The Curv's turret is fixed, at about 10.4cm. Measure your lowest gap: if it's between those two figures, only the CurvX will get under.

  2. 02

    Obstacles: better in the lab, messier at home

    In the same lab, Vacuum Wars recorded 20 of 24 obstacles avoided for the CurvX and 17 for the Curv, with a 17 average. RTINGS found the Curv missed cords and socks and bumped into pet waste. But the CurvX's three-month home test went worse: Vacuum Wars saw it try to climb toys, cables and cloths. Tidy up before a run with either.

    Carpet and hair: level in the lab

    Vacuum Wars measured both removing 92% of embedded sand from carpet, against a 77% average, and neither wrapped any hair round its brush. The difference with pets is the bin. The CurvX's is very small, and Vacuum Wars had it clog almost daily with a shedding dog, sometimes spitting hair back out. TechRadar had no trouble with the Curv in a home with five pets.

  4. 04

    Battery: the Curv covers a little more

    Vacuum Wars estimated about 155 square metres per charge for the Curv and 134 for the CurvX, both well above its average of about 102. Either should finish a typical home on one charge.

    Vacuum Wars floor covered per charge
    Qrevo Curv1,668 sq ft (155m²)
    Qrevo CurvX1,442 sq ft (134m²)
  5. 05

    Mopping: both strong, the CurvX is wetter

    RTINGS called the Curv's mopping among the best there is and great on dried stains. TechGearLab found the CurvX handled dried coffee and left floors mostly dry, but Vacuum Wars measured it putting down more than double the average water even on its lowest setting. Both lift their pads over carpet rather than leaving them behind, so check your carpet settings.

Questions people ask

What is the difference between the Qrevo Curv and Qrevo CurvX?

Mainly height. The CurvX's laser turret drops down so it's 7.98cm tall, against about 10.4cm for the Curv, whose turret is fixed. The CurvX also claims more suction and has a hotter mop wash. In Vacuum Wars's lab the two cleaned carpet equally well, and the CurvX avoided a few more obstacles.

Is the Qrevo CurvX better than the Qrevo Curv?

For most homes, yes, mainly because it fits under much lower furniture. The exception is a heavily shedding pet: Vacuum Wars found the CurvX's small bin clogged almost daily with dog hair.

Which is better for pet hair?

Both lifted hair well and tangled none in Vacuum Wars's lab. At home, the Curv coped with five pets for TechRadar, while the CurvX's tiny bin struggled with one shedding dog for Vacuum Wars. With a heavy shedder, the Curv is the safer pick.

Will either fit under my sofa?

The CurvX needs about 8cm of space and the Curv about 10.5cm. Those are the robots' heights, so measure your tightest gap and leave a little room for the robot to move.

Is the Qrevo CurvX the same as the Qrevo Curv 2 Pro?

No. They're similar slim designs with pop-down turrets, but they're separate models, and none of the tests on this page cover the Curv 2 Pro.
