The Qrevo CurvX wins on nearly every practical front: dual spinning mop pads that scrub at 200 RPM, a longer 220-minute runtime, an extendable side brush that reaches into corners, and a dock that cleans itself. The Narwal Flow counters with a roller mop, two side brushes, and a 3-year warranty that triples Roborock's coverage. For most homes with a mix of carpet and hard floors, the CurvX is the more complete cleaner, and it costs less too.
Roller mop versus dual spinning pads. That's the technical heart of this matchup, and it's a genuinely interesting one because roller mops are the newest mopping approach on the market, but newest doesn't automatically mean better executed. Narwal's Flow leans hard into its self-maintaining roller system, and Roborock's Qrevo CurvX answers with proven dual spinning pads, a self-cleaning dock, and an extendable side brush. Both use LiDAR plus cameras plus 3D structured light for obstacle avoidance, so navigation is a genuine draw. The rest of the comparison is where things separate, and price makes it more lopsided than you'd expect.
Narwal Flow
out of 10Roborock Qrevo CurvX
The Roborock Qrevo CurvX takes this one with an 8.9 overall rating against the Narwal Flow's 7.8. Cleaning is a big part of it: 8.7 versus 7.8 means the Roborock pulls more dirt out of carpet and handles messes with less fuss. The bigger gap is in features, 7.9 versus 5.7, so you get more useful extras and smarter automation. Navigation is a tie at 8.1 for both, and both get around a home well. The Roborock also gives you more for the money.
Mopping is the headline. The Flow uses a roller mop spinning at 110 RPM, an emerging technology that's promising but still maturing, and the CurvX uses dual spinning pads running at 200 RPM with 17 mm of lift versus the Flow's 12 mm. That extra lift matters when the robot crosses from tile onto a thick rug. Cleaning hardware splits differently: the Flow carries two side brushes, but the CurvX's single brush extends outward to sweep corners and edges, and its main brush lifts to protect carpets. Runtime favors Roborock at 220 minutes against 190, with 4,305 square feet covered in a single run. Narwal's counterpunch is coverage of a different kind: a 3-year warranty against Roborock's 1 year.
The CurvX pairs a dual rubber and bristle brush with an extendable side brush that reaches into corners the robot's body can't get to, plus a liftable main brush that keeps carpet fibers from tangling. The Flow's combo brush and two fixed side brushes cover more width on open floor, but they don't extend.
Dual spinning pads at 200 RPM give the CurvX active scrubbing pressure that the Flow's 110 RPM roller doesn't match, and 17 mm of mop lift keeps carpets drier than the Flow's 12 mm. Roborock also dries pads at 113 degrees versus 104, which cuts down on mildew smell.
Both docks swallow a similar amount of debris, with the CurvX holding slightly more in its dust bag. For heavy shedders, the CurvX's liftable main brush and 258 mL onboard bin give it the practical edge on longer pet-hair runs.
This one is a genuine tie. Both robots combine LiDAR, cameras, AI, 3D structured light and an LED for low-light obstacle spotting, and both rate 6.92 for navigation, so expect similar behavior around chair legs and stray socks.
Roborock's dock does more: it self-cleans, holds 4 L of clean water and 3 L of dirty water, and dries pads at a higher temperature. The Flow's dock handles self-emptying and mop washing too, but without the self-cleaning step you'll be wiping the tray yourself more often.
The CurvX runs 220 minutes and covers 4,305 square feet in one go, enough for most single-story homes without a mid-clean recharge. It also supports off-peak charging to top up when electricity rates drop. The Flow's 190 minutes is still solid for apartments and mid-size homes.
Both cover the essentials: voice control, no-go zones, multi-level maps and smart carpet cleaning. Roborock spells out support for its built-in assistant plus Amazon, Google and Apple platforms, so it slots into whichever ecosystem you already use.

The Qrevo CurvX is the stronger all-around machine and the cheaper one, which makes it an easy call for most buyers. The Flow earns its place if a 3-year warranty and roller mop technology speak to you specifically. Otherwise, Roborock's mopping, runtime and dock automation do more of the work for you.
