Mopping style is the real fork in the road here. The Narwal Flow 2 uses a roller mop with 12 N of downward pressure and a bigger onboard water tank, plus 30,000 Pa of suction for deep carpet work, making it the pick for homes with lots of hard floor and heavy pet shedding. The Roborock Saros 10R counters with dual spinning mop pads that lift 10 mm for carpets, a dual brush system, an extendable side brush, and a dock with 4 L clean and 3 L dirty water tanks, which suits large multi-room homes that want longer unattended runs.
Roller mop versus dual spinning pads. That's the headline matchup between the Narwal Flow 2 and the Roborock Saros 10R, and it's a genuinely interesting one because these are the two most capable mopping approaches on the market right now. Both robots run LiDAR plus camera navigation, both empty themselves, both wash and dry their own mops with hot air. So the decision comes down to how each one handles floors, how much your dock needs to hold, and whether raw suction numbers or broader automation features matter more in your house. They land in the same price range, which makes the feature trade-offs the whole story.

out of 10Roborock Saros 10R
The Saros 10R takes the overall rating 8.92 to 8.45. It leads on cleaning at 7.45 versus 6.72 and on features at 7.31 versus 6.20, helped by its dual brush setup, extendable and liftable side brush, and a dock with larger water tanks. The Flow 2 flips the script on navigation, 8.44 versus 7.68, thanks to its dual HD camera setup working alongside LiDAR. Value tips toward the Saros 10R, rated good for the price, with the Flow 2 rated as priced about right.
Suction splits them wide open: 30,000 Pa on the Flow 2 against 19,000 Pa on the Saros 10R. But the Roborock answers with a dual brush system rather than a single brush, which grabs debris across a wider path, plus an extendable side brush that reaches into corners and a liftable one that stays out of the way on carpet. Mopping goes the other direction. The Flow 2's roller mop is the newest approach and applies 12 N of pressure at 80 RPM with a roughly double-size onboard water tank. Roborock's dual spinning pads lift 10 mm to clear carpet and can detach automatically before vacuuming. Then there's the dock: the Saros 10R holds 4 L of clean water and 3 L of dirty water, and washes pads at 176 degrees F versus 140 degrees F.
The Flow 2 brings 30,000 Pa against the Saros 10R's 19,000 Pa, but the Roborock uses a dual rubber and bristle brush plus an extendable side brush that pushes into corners and along baseboards. Higher suction on one side, better debris pickup mechanics on the other, which is why this one lands even.
Narwal's roller mop is the newest mopping technology available, pressing down with 12 N at 80 RPM and drawing from an onboard water tank roughly double the Roborock's, so it stays wet longer between refills. The Saros 10R's dual spinning pads are still excellent and lift 10 mm to clear carpet, but the roller edges it out on continuous scrubbing.
Pet hair is where the Flow 2's 30,000 Pa earns its keep, pulling embedded fur out of rugs and upholstered edges. The Saros 10R's slightly larger 2.7 L dust bag holds a bit more between changes, but the suction gap decides this one.
Both use AI, cameras, and 3D structured light for obstacle avoidance, and both run LiDAR. The Flow 2's dual HD cameras give it sharper object recognition in practice, and it takes the navigation rating, though the Saros 10R adds a headlight for dark rooms and stores up to four floor maps.
Roborock's dock is the more self-sufficient one, with a 4 L clean water tank and a 3 L dirty water tank so it can run several sessions before you touch it. It also washes mop pads at 176 degrees F versus 140 degrees F, though Narwal dries at the higher 140 degrees F.
The Saros 10R covers 2,150 sq ft in a single run with up to 180 minutes of runtime, and it supports off-peak charging so it tops up when electricity is cheaper. The Flow 2 carries a larger 7,000 mAh battery against 6,400 mAh.
Dead even here. Both support built-in voice control plus Amazon Alexa, Google Assistant, and Apple, and both handle no-go zones, multi-level maps, smart carpet cleaning, and smart obstacle avoidance.

Both are top-tier machines and you won't regret either. Go Narwal Flow 2 if pet hair and hard floor mopping dominate your cleaning routine. Go Roborock Saros 10R if you want the more hands-off dock, longer single runs, and smarter edge and carpet handling across a bigger home.
