Narwal Flow 2 vs Roborock Saros 10R: Which Robot Vacuum Fits Your Home?
The Roborock Saros 10R is the lighter and lower robot (4.1 kg and 79.8 mm versus 5.0 kg and 95 mm), while the Narwal Flow 2 lists a longer 190-minute runtime against 180 minutes, a 7.0 Ah battery against 6.4 Ah and a rolling track mop. Here is how their published specs compare.

Weighing 9.0 lb (4.1 kg) against 11.0 lb (5.0 kg), the Saros 10R is the lighter robot, and at 79.8 mm tall it is also the lower one. In the Narwal Flow 2 vs Roborock Saros 10R matchup, the Flow 2 robot vacuum answers with a rolling track mop, a large base station dust bag and a slightly longer listed runtime, while the Saros 10R robot vacuum is a very low-profile robot whose dock handles its mop. Both are self-emptying robot vacuum and mop combos. This comparison uses manufacturer specifications and our catalog; we have not tested either robot.
Narwal Flow 2 vs Roborock Saros 10R at a glance
- Choose the Flow 2 if you want a long gap between dust bag changes (Narwal lists up to 120 days, or 90 days in pet households), a rolling track mop and an optional plumbed refill-and-drainage dock.
- Choose the Saros 10R if furniture clearance or carrying weight matters, you want a dock that mounts and removes the mop for you, and you prefer a clearly stated 1-year limited warranty.
Neither choice is universally better. They are built around different priorities, and the specs below show where.

Weight, runtime and battery
Our catalog gives the Flow 2 a weight of 11 lb (5.0 kg) and the Saros 10R 9 lb (4.1 kg), a 0.9 kg difference. The Flow 2 figure comes from a review site because Narwal does not publish it, so treat both as approximate. The gap matters mostly if you carry the robot between floors.
On runtime, listings show 190 minutes for the Flow 2 and 180 minutes for the Saros 10R, only a 10-minute difference. Both come from review sources rather than manufacturer pages, and real runtime depends on suction mode and floor type. The battery figures run the same direction: 7.0 Ah for the Flow 2 against 6.4 Ah for the Saros 10R. The Saros 10R is marketed with 2.5-hour fast charging; Narwal does not publish a charge time.
Mop systems and docks
The Flow 2 uses what Narwal calls the FlowWash rolling track mop, which it describes as cleaning itself while it mops. The base station dries the mop with warm air, and an optional plumbed auto refill and drainage dock can take manual water-tank handling out of the routine if you can run plumbing to it. Plan for the installation before assuming it fits your layout.
The Saros 10R takes a different route. Its 10-in-1 Multifunctional Dock 4.0 can mount and remove the mop automatically, and the robot's FlexiArm riser side brush and mop reach toward edges. The dock is part of what you are buying, so check what footprint it needs before ordering. Roborock's page we checked gave no dock bag capacity, so a bag-life comparison is not possible.
Carpet, sensing and Wi-Fi
Both robots lift the mop over carpet in their own way. The Flow 2 identifies carpet with CarpetFocus and raises the mop. The Saros 10R's AdaptiLift system raises the chassis by 10 mm and the mop by 17 mm, which helps with thresholds and rugs.
For sensing, the Flow 2 uses dual 1080p AI cameras (TwinAI Dodge) for obstacle avoidance. The Saros 10R navigates with StarSight Autonomous System 2.0 and uses VertiBeam sensing for lateral obstacle avoidance. Different sensor approaches do not tell you which will avoid cables or pet accidents better in your home; independent testing would be needed for that.
One practical detail: the Saros 10R works on 2.4 GHz Wi-Fi only, so check your router if it combines bands.
Choosing for your home, and the limits of a spec comparison
- Pet households and long hands-off stretches: the Flow 2's bag interval is the main draw, with a shorter 90-day figure for pets.
- Low furniture or stairs: the Saros 10R's 3.14 in height and lower weight are measurable advantages. Measure your gap first.
- Mixed carpet and hard floors: both lift the mop; compare how much lift you need for your rugs.
- Warranty clarity: Roborock states a 1-year limited warranty on its US page; the Narwal US page we checked does not state a standard term, so confirm it before buying.
Spec sheets leave out what matters most day to day: real cleaning performance, noise in use, app quality and long-term reliability. Some figures come from reviews and non-US pages, so where manufacturers disagree or are silent we left the figure out rather than guess. Browse more from each brand through the Narwal vacuum and Roborock pages, see other Roborock robot vacuum reviews if the Saros 10R is close but not right, or compare vacuum specs side by side the same way.
The Flow 2 is also compared with the Qrevo Curv 2 Flow in a separate page, and with a Narwal sibling in Flow 2 vs Freo Z10 Ultra.

Does the Roborock Saros 10R work on 5 GHz Wi-Fi?
No. Roborock's US product page says the Saros 10R supports 2.4 GHz Wi-Fi only and that 5 GHz is not supported. If your router combines 2.4 and 5 GHz under one network name, you may need to use the 2.4 GHz band or split the bands during app setup. The Narwal Flow 2 comparison on this page does not cover its Wi-Fi bands because we could not confirm them from the manufacturer page.
How often does the Narwal Flow 2 need a new dust bag?
Narwal's US product page lists a 2.5 L dust bag in the base station that lasts up to 120 days, dropping to 90 days for households with pets. Actual intervals depend on how much debris you have and how often it runs. The Roborock Saros 10R also empties itself into its Multifunctional Dock 4.0, but Roborock's page we checked gave no bag capacity or interval to compare.
