One brand sells a handful of machines and documents them properly. The other sells a machine for every budget and documents the ends of the range. Which matters depends on where in it you are shopping.
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.
Narwal publishes a mop lift height on both machines we can confirm on sale; Roborock publishes one on two of its seven. Roborock covers far more price points and is the only one of the two publishing a body height. Buy Narwal for documented mopping, Roborock for choice and for low furniture.
This is a comparison between two very different shapes of company, and the honest starting point is that they are not the same size here. We can confirm seven Roborock machines currently on sale and two Narwals. Narwal sells more models than that in the US; those are the two we have been able to price and specify against the maker's own current pages, and we do not rank machines we cannot confirm.
So read this as a comparison of habits rather than of catalogs. The question is not which brand has more boxes on the shelf - Roborock plainly does - but what each one tells you about the box you are considering.
The row where Narwal wins outright
Mop lift height is the specification that decides whether a mopping robot can be trusted in a house with rugs, and it is the single most commonly omitted figure in the whole category.
Published mop lift, both brands, every model we cover
4 of 8 models publish this figure. Every number below links to the page it came from.
Compiled from the manufacturers’ own published material — every row carries the date its figure was read. We have not measured any of these figures ourselves, see how we pick. Found an error? Tell us and we will correct it.
Both Narwals publish a figure. Two of seven Roborocks do. And the two that do are the two most expensive machines Roborock sells here - the Qrevo CurvX and the Saros 10R, both at 17mm. Everything in Roborock's middle and lower range, including machines that mop, leaves the row blank.
Roborock's 17mm is the higher figure and the highest on this site, so if you are comparing flagship against flagship it wins the number. But if you are shopping anywhere below the top of Roborock's range and mopping matters, Narwal is the brand that will still tell you. Our mop lift table puts every model we cover side by side.

Counted across the models each brand currently has on sale and this site covers. Narwal sells more US models than the two we can confirm and specify; we do not count machines we have not verified. Every underlying figure is sourced on that model's spec sheet.
Narwal fills a higher proportion of rows, which is easier to do across two machines than across seven - we should be fair about that. The more interesting comparison is the shape of the gaps. Roborock's blanks cluster in the middle of its range; Narwal's are spread thin across both machines. Neither brand publishes a runtime or a dustbin capacity for anything, which is a shared blind spot worth naming.
Where Roborock wins, and it is not close
Two things, and the first is the one most buyers will actually feel.
Choice. Roborock sells machines at seven price points we can confirm, from an entry model that still publishes a real suction figure up to a flagship. Narwal's two confirmed machines sit in the upper middle and at the top. If your budget is at the bottom of the market, Narwal does not currently have an answer we can verify and Roborock has several - see the best Roborock.
Body height. Roborock states a figure on three of seven machines and two of those are 80mm, the flattest anyone here publishes. Narwal states one on a single model, and it is 107.7mm - nearly 28mm taller. If your furniture sits low, that difference decides whether the robot cleans under it or stops at the edge. See which robots fit under furniture.
Roborock also publishes the higher suction figures across most of its range, though both brands post numbers from their own rigs and the top Narwal figure is the highest on this site. That row is the least useful one here and we would not decide on it - the reasoning is on the suction chart.
How we picked
Criteria first, products second. These are the things we ranked on, stated before anything is recommended.
Count filled rows across each brand's whole purchasable range, not just its best model. A brand that documents its flagship and nothing else is harder to shop than one that documents consistently.
Judge breadth separately from depth. Roborock sells machines at far more price points than Narwal. That is a real advantage and we say so rather than pretending the two ranges are the same size.
Compare only where both publish. Where one side is blank we mark it blank rather than filling it with an estimate.
Pa figures rank within a brand, not across one. Narwal's rig and Roborock's rig are different rigs.
No durability or reliability claims in either direction. We have not run these machines for years. See how we pick.
What we did not do: test any of these machines. We do not own one, we do not have a lab, and nothing on this page is written as though we did. The full method.

Narwal also states the base station washes at up to 212F.Source: Narwal Flow 2 product page — base station (retrieved 2026-09-26)
What it does well
Publishes more rows than any other roller mop here, including a noise figure most makers omit
12mm mop lift is published, so the carpet question has an actual number behind it
Dock bag stated at 2.5L and up to 120 days, the longest stated interval of any machine on this site
What it does not
The most expensive roller mop we cover by a clear margin
No published climb height, so thresholds are an unknown
No published body height or runtime, despite publishing a battery capacity
Who it is for
Someone buying the mechanism rather than the badge, who wants the specification available before spending flagship money.
Skip it if
Your budget is the constraint. This is the most expensive roller mop we cover, and the eufy C28 brings the same idea in for a lot less.

Auto-washing, auto-drying and self-emptying, with stated wash temperatures of 45C for starch and 60C for grease plus a 72C pasteurization cycleNarwal is the only maker we cover that states more than one wash temperature and ties each to a soil type. It does not state a self-empty interval for this model.Source: Narwal Freo Z10 Turbo product page — base station (retrieved 2026-10-03)
What it does well
Publishes suction, climb height, mop lift and body height — four rows most rivals leave blank at this price
Three stated wash temperatures, including a 72C pasteurization cycle
12mm mop lift, so the carpet question has a number behind it
What it does not
A 20mm climb figure is unremarkable — several cheaper machines match it
No published runtime, dustbin capacity or self-empty interval
The anti-tangle claim is a name and a promise rather than a described mechanism
Who it is for
Someone who wants a well-documented all-in-one dock and does not need the flagship's roller mop.
Skip it if
Your thresholds are over 2cm. Narwal publishes a 20mm climb figure for this one, which is the ordinary figure rather than a good one.
It has a hot-water mop washing dock with auto drying, which is real hardware. It is the skip because it is the emptiest sheet in this comparison from either brand: 7,000 Pa, no climb height, no mop lift, and a main brush Roborock never describes. Against a Narwal range where both machines publish a mop lift and both describe their brush, it is the clearest illustration of the point this page is making.
Which brand for which buyer
Mopping is the main job and you have rugs - Narwal. Both machines publish a mop lift figure, which is more than five of Roborock's seven manage.
You want the specific dock claim rather than the vague one - Narwal, for the per-soil-type wash temperatures and the 120-day dock interval on the Flow 2, the longest stated interval of any machine on this site.
Low furniture - Roborock, decisively. The 80mm bodies have no Narwal equivalent we can confirm.
A tight budget - Roborock. It is the only one of the two with machines at the bottom of the market, and the Q7 M5+ publishes more than most machines twice its price.
You want a roller mop specifically - Narwal's Flow 2 is one of only three roller-mop robots we can confirm on sale; Roborock sells none. The whole field is on robot vacuums with a roller mop.
Thick thresholds - Roborock's Qrevo CurvX at a published 40mm beats the one Narwal climb figure we have, which is 20mm. Check both against the threshold table.
Questions people actually ask
+ Is Narwal better than Roborock?
Neither of us has tested them, so we cannot answer that. On published specification Narwal documents both of its machines more completely than Roborock documents its middle range, particularly on mop lift. Roborock sells at far more price points and is the only one of the two publishing a body height worth having.
+ Does Narwal publish more than Roborock?
Proportionally yes, but across a much shorter line - two machines against seven, which makes a high hit rate easier. The meaningful finding is that both Narwals publish a mop lift height while only Roborock's two most expensive machines do.
+ Which is better for mopping, Narwal or Roborock?
Roborock holds the highest published mop lift at 17mm, on its two most expensive machines. Narwal publishes 12mm on both of its, states wash temperatures by soil type, and sells one of the three roller mops we can confirm on sale. For flagship-against-flagship, Roborock has the bigger number; below that, Narwal is the brand still telling you.
+ Why do you only cover two Narwal machines?
Because those are the two we could both price against a live retail listing and specify against Narwal's own current product pages. Narwal lists more US models than that, and at least one older model is still sold on Amazon but no longer appears in Narwal's current lineup, so we cannot source its specification from the maker. We do not rank machines we cannot verify.
+ Is Narwal a reliable brand?
We have no basis to judge reliability for Narwal or for anyone else on this site, and we will not invent one. We have never run these machines, and nobody has published long-run failure data we would cite. What we can tell you is what each maker commits to in writing, which is what every page here is built on.
