Roborock, for most homes: it vacuums carpet more consistently, its flagships fit under much lower furniture and its app is easier to live with. Pick Narwal if mopping hard floors matters most, because nearly every tester rated its mops among the best they had used.
Updated
Start with the thing that matters most to you.
Narwal's mops are its strength. Vacuum Wars called the Flow 2 the best robot mop it had used at home, and TechRadar called the Freo Z Ultra the best mopping robot it had tested.
Roborock's Saros 10 and Qrevo CurvX drop their turrets to just under 8cm. Narwal's robots stand about 9.5cm to 11cm, and techreviewer measured the Freo Z10 Ultra at 10.96cm with a turret that doesn't retract.
Vacuum Wars measured the Qrevo CurvX's carpet deep clean among the very best it has tested. techreviewer found the Freo Z10 Ultra left more grit in carpet than top Roborock models.
Both brands have good options. Vacuum Wars saw no clogs or tangles in three months with the Flow 2 and a shedding dog, and TechRadar found the Saros 10 cleared a cocker spaniel's hair for ten months. Avoid the CurvX with a heavy shedder: its small bin clogged almost daily Vacuum Wars.
T3 said no other robot vacuum app comes close to Roborock's. Narwal's drew complaints: TechRadar found it overwhelming, and Vacuum Wars couldn't turn off a night-time voice alert.
The closest match from each brand at three price levels, with today's prices.
The Freo Z10 Turbo mops better and handled a shedding dog well The Gadgeteer, but it has no camera and ran through dog waste for CGMagazine. The Qrevo CurvX is lower and stronger on carpet TechGearLab, but its tiny bin clogged with dog hair at home Vacuum Wars.
The Flow 2 is the better mop and dodged cables for three months Vacuum Wars, but Tom's Guide saw it push cereal around and leave corners for hand cleaning. The Saros 10 vacuums more consistently, gets under much lower furniture and ran ten months with few rescues TechRadar.
Narwal is a mop-first brand, and reviewers agree on that part. Every Narwal here got top marks for mopping, from the original Flow Vacuum Wars to the Freo Z10 Turbo The Gadgeteer. The camera models also dodge clutter well: Vacuum Wars recorded its best-ever obstacle score on the Freo Z Ultra. Vacuuming is the weaker side. RTINGS found the Flow's routes missed whole areas of floor, and TechRadar gave up on fine dust in carpet after three attempts. Some testers also hit setup and reliability problems, with TechRadar seeing the Z10 Ultra skip rooms and fail to empty its bin.
Roborock's robots are the better all-rounders. Every test of the Saros 20 rated its hard floors highly RTINGS, and the Saros 10 cleared a cocker spaniel's hair from carpets over ten months TechRadar. The flagships are low enough for most sofas and the newer ones climb doorway thresholds well TechRadar. Mopping is good rather than class-leading: the Saros 10R and Saros 20 mop well Vacuum Wars Expert Reviews, but the Saros 10's vibrating pad needs its stronger settings on dried stains Trusted Reviews.
This is where Narwal earns its place. Vacuum Wars put the original Flow's mopping in its top seven of all time, Trusted Reviews saw dried coffee and red wine cleared in one pass by the Flow 2, and Vacuum Wars found the Freo Z Ultra beat a floor washer on dried stains. Roborock's Saros 10R mops well too Vacuum Wars, but the Saros 10 left dried ketchup barely touched on its Standard setting TechRadar.
Narwal's vacuum results swing a lot. RTINGS rated the Flow poor on hard floors and carpet because its routes missed large areas, and Tom's Guide watched the Flow 2 crush cereal and push it around. Roborock's results line up better: RTINGS found almost complete hard-floor pickup on the Saros 20, and Trusted Reviews saw a flour spill on carpet almost entirely gone with the Saros 10.
Narwal's robots are tall. The Flow 2 fitted under a sofa but not kitchen cabinets for TechRadar, and the Freo Z10 Ultra's turret doesn't retract techreviewer. Roborock's Saros 10 and Qrevo CurvX lower their turrets to get under gaps of about 8cm, and Vacuum Wars found the CurvX reached deep under beds.
Vacuum Wars recorded its best-ever obstacle score on the Freo Z Ultra, and Vacuum Wars never had the Flow 2 stuck on a cable in three months. The camera-free Z10 Turbo is the exception: CGMagazine's ran through dog waste. Roborock varies by model, from the Saros 10R's perfect obstacle score Vacuum Wars to the CurvX, which tried to climb toys and cables at home Vacuum Wars.
Roborock's app is a regular highlight, and T3 said no other robot vacuum app comes close for depth and ease of use. Narwal's needs more patience. TechRadar found a lounge carpet silently marked as no-clean, TechRadar found key settings buried, and The Gadgeteer overrode the automatic mode for two days before trusting it.
Only for mopping. Narwal's mops scored among the best in almost every test Vacuum Wars TechRadar, but Roborock vacuums more consistently, fits under lower furniture and has the easier app T3. For most homes, especially with carpet, Roborock is the safer buy.
It depends on the model more than the brand. The Narwal Flow 2 had no clogs or tangles in three months with a shedding dog Vacuum Wars, and the Z10 Turbo lifted most dog hair from a low rug in one run The Gadgeteer. Roborock's Saros 10 kept up with a cocker spaniel for ten months TechRadar, but the Qrevo CurvX's small bin clogged almost daily with a heavy shedder Vacuum Wars.
Low rugs, yes; deep carpet, less so. The Gadgeteer found the Z10 Turbo cleared a low rug but needed a second run on medium pile, and TechRadar gave up on fine dust in carpet with the Freo Z Ultra. Narwal mops lift rather than detach, so Trusted Reviews suggests a robot that drops its mop for deep pile.
Narwal's camera models and Roborock's Saros 10R are the best here. Vacuum Wars recorded its best-ever obstacle score on the Freo Z Ultra, and RTINGS found the Saros 10R great at avoiding pet waste. Skip the camera-free Narwal Z10 Turbo if your pet has accidents: one ran through dog waste CGMagazine.
There isn't enough long-term testing to say. The longest reports are three months with a Flow 2, with only two interventions Vacuum Wars, and ten months with a Saros 10, with few rescues TechRadar. None of the reviews we use judged either brand's support.
