Disclosure — some links on this page go to Amazon, and we earn a commission if you buy through them. It costs you nothing extra and it does not change what we recommend or in what order. The full disclosure.

Roborock publishes 7 of the 9 specifications we track for this model and states nothing about the other 2. Everything below is quoted from Roborock’s own material, with the page it came from linked on each row. We have not handled this machine.

The Curv is the model that makes this site's flagship table possible. Roborock publishes two threshold figures for it rather than one — 30mm for a standard sill and 40mm for a double-layer one — and states which is which. That distinction sounds pedantic until you measure your own doorway and discover that a stepped sill and a single vertical face are genuinely different obstacles.

Everything else about it is a competent flagship rather than a remarkable one. 18,500 Pa is a large number that means little across brands, the DuoDivide brush is described in enough detail to be credible, and the dock does the full wash-dry-empty-refill routine. The 104mm body is the real cost: it is a tall robot, and it will stop at furniture the 80mm models drive under.

What the sheet says it does well, and what it does not

Strengths

Roborock publishes a standard-threshold figure and a double-layer figure separately, which almost nobody else does
17mm of mop lift is enough to keep a wet pad off medium-pile carpet
Anti-tangle design on the main brush and the side brush, not just one of them

Limits

The 40mm headline is a double-layer threshold, not a single 40mm step — read the condition, not the headline
104mm (4.1in) tall, so it will not fit under a low sofa or a kickboard gap

Who it is for

Older houses with real door sills, and anyone whose current robot announces itself stuck in the same doorway every day.

Who should skip it

Your floors are flat and open. You would be paying a premium for chassis hardware your home never asks for.

How we assessed this

By reading what Roborock publishes and recording it with its source. We have never owned, handled or measured this machine, and nothing above is written as though we had. Where the manufacturer publishes nothing, the row says so rather than borrowing a number from somewhere else. The full method is on how we pick, and if a figure here does not match the page it links to, tell us and we will correct it with a date.

What the spec sheet does not tell you

2 of the figures we track are absent from Roborock’s own material for this model. That is worth knowing before you buy, because each of them answers a question somebody eventually asks:

Stated runtime — Not stated on the Roborock product page.
Dustbin — Not stated on the Roborock product page.

We could fill those in from a review site or an estimate. We do not, because a number we cannot source is worth less than an honest blank, and the pattern of what each maker will and will not state is one of the more useful things on this site.

Questions people actually ask

+ Does Roborock publish a threshold climb height for the Roborock Qrevo Curv?

Yes — 40mm (1.6in) double-layer, 30mm (1.2in) standard. Roborock's own wording is that it can overcome standard thresholds up to 3cm and navigate double-layer thresholds up to 4cm. Stated maxima assume a clean square edge; a rounded or worn sill behaves differently. Compare it against every other model on the cross-brand climb table.

+ What suction does the Roborock Qrevo Curv have?

Roborock states 18,500 Pa. Stated as peak suction, not sustained. Remember that pascal ratings are not standardized between manufacturers, so that figure ranks this model within Roborock's own range and does not compare across brands — the full explanation.

+ Is the Roborock Qrevo Curv good for pet hair?

Its main brush is described as duodivide dual rubber-bristle main brush, which is the specification that matters most in a hair-heavy house — more than suction. The brush comparison sets out what each design does.

+ Can the Roborock Qrevo Curv mop over carpet?

Roborock states a mop lift of 17mm. Compare that against your own pile depth rather than against other models — mop lift compared.

+ Who should skip the Roborock Qrevo Curv?
