Both robots use roller mops and the same LiDAR-plus-camera navigation stack, so the real split comes down to automation depth and cleaning muscle. The Mova Z60 Ultra Roller SA brings 26,000 Pa suction, an extendable side brush, liftable brushes, auto detergent dispensing, and a hotter mop-drying cycle, making it the stronger pick for homes with carpet, pets, and lots of edges. The Narwal Flow makes sense if clearing taller obstacles, mapping a fourth floor level, and a documented 57 dB vacuum noise level matter more than the extra automation.
Roller mops are still the newest approach to robot mopping, and here are two robots that both use one. That shared foundation makes the rest of the comparison sharper than usual. The Mova Z60 Ultra Roller SA pushes harder on suction, dock automation, and brush lifting, and it does it at a price well below the Narwal Flow. The Flow answers with a taller obstacle clearance, a fourth mapping level, two side brushes, and a published noise figure. So the question isn't which technology is newer. It's how much automation you want, and how much you're willing to pay for it.
Mova Z60 Ultra Roller SA
out of 10Narwal Flow
The gap here is wide. Overall, the Mova Z60 Ultra Roller SA earns a 9.12 rating against the Narwal Flow's 7.78. Cleaning is closer at 7.41 versus 6.65, and navigation is dead even at 6.92 for both. The real separation shows up in features, 7.26 versus 4.18, driven by things like auto detergent dispensing, liftable brushes, and off-peak charging. On value, the Z60 Ultra Roller SA delivers more than its price suggests, and the Flow lands about where it should.
Suction is the headline number: 26,000 Pa on the Z60 Ultra Roller SA versus 22,000 Pa on the Flow, backed by a bigger 3.2 L dust bag against 2.5 L. The Mova also lifts both its main brush and side brush, and extends that side brush out to reach corners and baseboards, features the Flow doesn't offer. Dock behavior separates them too. The Z60 Ultra Roller SA adds detergent automatically when it washes the roller and dries it at 145 °F, compared with 104 °F on the Flow. The Flow counters where it counts for cluttered rooms, clearing obstacles up to 40 mm versus 22 mm and storing maps for four floors instead of three. It also runs two side brushes to the Mova's one.
The Z60 Ultra Roller SA pairs 26,000 Pa with a dual rubber-and-bristle brush, a 210 mL onboard dustbin, and a side brush that extends outward to sweep debris from along walls. The Flow's combo brush and two side brushes cover more ground per pass, but 22,000 Pa and no extendable arm put it a step behind on edges and embedded debris.
Both use roller mops, the most effective mopping design available right now, so neither is at a disadvantage on wet cleaning. The Flow applies 12 N of mop pressure and spins at 110 RPM, and the Mova offers 32 moisture levels plus a slightly higher 14 mm mop lift for stepping over carpet.
For shedding households, the Mova's extra 4,000 Pa of suction and 3.2 L dust bag mean fewer clogged passes and longer stretches between bag changes compared to the Flow's 2.5 L bag.
These two run identical obstacle avoidance hardware (AI, camera, 3D structured light, and an LED), which is why their navigation ratings match at 6.92. The Flow pulls ahead on practical reach, climbing thresholds up to 40 mm versus 22 mm and holding maps for four floors instead of three.
The Mova dock does more work: it adds detergent automatically when washing the roller for a cleaner mop, dries at 145 °F versus 104 °F, and holds 4 L of clean water plus 3.5 L of dirty water across multiple sessions. The Flow washes with water only.
The Z60 Ultra Roller SA runs up to 220 minutes against the Flow's 190, and it can schedule charging during off-peak electricity hours. That extra half hour matters most in larger single-story homes.
Both handle voice control, no-go zones, multi-level maps, smart carpet cleaning, and smart obstacle avoidance, so the everyday app experience lands in similar territory. The Mova adds a built-in voice assistant alongside Amazon Alexa and Google support for hands-free commands without opening the app.

For most homes, the Mova Z60 Ultra Roller SA is the easier call. It cleans harder, runs longer, automates more of the mop upkeep, and costs considerably less. The Narwal Flow earns its place in multi-story homes with tall thresholds where 40 mm of clearance and four-floor mapping solve a real problem.
