The Narwal Flow leans on a roller mop that scrubs with 12 N of downward pressure and gets backed by two side brushes, making it the stronger pick for hard floors and edge pickup. The Roborock Saros 10 counters with a deeper automation stack: automatic mop pad detachment before carpet, detergent added during dock washing, a liftable main brush and side brush, an extendable side brush, and a 140 °F drying cycle. Pick the Flow for cleaning fundamentals and a longer warranty, the Saros 10 for the hands-off dock experience and longer runtime.
Two very different philosophies show up once you look past the shared LiDAR, cameras, and self-emptying docks. Narwal built the Flow around its roller mop, a continuously rinsed scrubbing surface that presses down hard and covers ground with a rotating cylinder rather than a pad. Roborock went the other direction with the Saros 10, stacking automation on top of a vibrating mop pad: pads that detach themselves for carpet, a brush that lifts, a side brush that extends into corners, and detergent mixed in during dock washing. One prioritizes how the floor gets cleaned. The other prioritizes how little you have to touch it.

These two land close together overall, 7.78 for the Flow versus 7.69 for the Saros 10, so neither runs away with it. The Flow edges ahead on cleaning at 6.65 versus 6.24 and navigation at 6.92 versus 6.61. The Saros 10 takes a wide lead on features, 8.38 versus 4.18, which comes down to its long list of automation extras. Both sit at a fair price for what they deliver, and both are excellent. It really comes down to which side of that split matters more in your home.
Mopping hardware splits them first. The Flow uses a roller mop, the newest approach on the market, rotating at 110 RPM and pressing down with 12 N. The Saros 10 relies on a vibrating pad running at 4,000 vibrations per minute with 8 N of pressure, plus a small rotating edge pad for baseboards. Brush layouts differ too: the Flow runs two side brushes for wider debris sweeping, the Saros 10 runs one that extends outward and lifts when it hits carpet, alongside a dual rubber and bristle main brush that also lifts. Then there's automation depth. The Saros 10 detaches its own mop pads before carpet, self-cleans its dock, adds detergent during washing, and dries pads at 140 °F versus the Flow's 104 °F. Narwal answers with a 3 year warranty against Roborock's 1 year.
The Saros 10 pairs a dual rubber and bristle main brush with a single side brush that extends into corners and lifts off carpet, plus a 270 mL onboard dustbin. The Flow answers with two side brushes and a combo bristle and rubber roller, which sweeps a wider path toward the intake on open floors.
Roller mops are the newest and most capable mopping design out there, and the Flow's version presses down with 12 N against the Saros 10's 8 N from its vibrating pad, which runs at 4,000 vibrations per minute alongside a small rotating edge pad. Roborock takes the automation side though, lifting its mop 18 mm versus 12 mm on carpet, detaching pads on its own, and drying them at 140 °F instead of 104 °F.
Both handle pet hair the same way in practice, with tangle-resistant rubber elements in their main brushes and full self-emptying docks so shed fur ends up in the base rather than a bin you empty daily. Neither pulls ahead here.
Both use LiDAR mapping with a camera and 3D structured light for obstacle avoidance, so cords, socks, and chair legs get handled well either way. The Flow adds an LED illuminator and a second RGB camera, which helps it identify objects in dim rooms.
The Saros 10's dock does more: it holds 4 L of clean water and 3 L of dirty water, cleans itself, adds detergent while washing the mop pads for a deeper clean, and dries them at 140 °F. The Flow's dock dries at 104 °F and washes with water alone.
Roborock runs longer, 220 minutes against 190 minutes for the Flow, and covers up to 2,500 sq ft in a single outing. It also supports off-peak charging, so the dock can top up when electricity rates drop.
Both cover the essentials: voice control, no-go zones, multi-level maps, smart carpet cleaning, and smart obstacle avoidance. The Saros 10 spells out its voice support across Amazon Alexa, Google Assistant, Apple, and a built-in assistant.

Neither of these is a mistake. Go with the Narwal Flow if you want stronger mopping hardware, wider edge sweeping, and a longer warranty. Go with the Roborock Saros 10 if the appeal is a robot that adjusts itself for carpet, runs longer, and asks less of you between cleanings.
