Side-by-Side Comparison
| Spec | Narwal Flow Robot Vacuum and Mop | Roborock Saros 10R |
|---|---|---|
| Price | $899.99 | $1099.99 |
| Release Year | 2025 | 2025 |
| Claimed Suction (Pa) | 22,000 Pa claimed — the identical number Roborock prints on the Saros 10R, and 12,000 Pa above the SwitchBot S20 that costs the same. The figures are measured differently by every brand and should not be read as a ranking | Sources conflict on Roborock's own number. Announced at 19,000 Pa at CES 2025 and still listed as 19,000 Pa in Vacuum Wars' 2026 Roborock guide; marketed as 22,000 Pa on Amazon, Best Buy and in Gizmodo's coverage; and listed as 18,000 Pa by one third-party spec database. Same robot, three numbers, no hardware change |
| Independent Test Result | Vacuum Wars ranked the Flow #2 overall: top-7 all-time for mopping, the best battery-efficiency score they have recorded, 0% hair tangling, strong pet-hair pickup. Consumer Reports ran a first-look review. Weak spot: fine hard-floor debris needs multiple passes | Vacuum Wars: a perfect 24/24 on obstacle avoidance, 92% flattened pet-hair pickup against an 80% average, 0% hair tangling against 39%, 80% carpet deep clean, and a 103-point dried-stain mopping score against a 98 average. RTINGS names it their top robot vacuum for 2026 |
| Navigation & Obstacle Avoidance | Semi-recessed 180-degree spinning LiDAR plus dual RGB AI cameras with LED lighting, 200+ object types. Vacuum Wars' complaint is that the avoidance behaviour is barely configurable | StarSight 2.0 dual-transmitter solid-state LiDAR plus 3D time-of-flight and an RGB camera — 21,600 sensor points, 108 object types — with VertiBeam for lateral detection |
| What the Maker Promises About Pet Waste | Narwal lists pet waste among the objects the dual-camera system recognises but publishes no replacement guarantee if it fails | Pet waste is in Roborock's recognised-object list and the robot scored 24/24 on Vacuum Wars' obstacle course, but Roborock publishes no replacement guarantee of the kind iRobot offers on the j7+ |
| Mop System | FlowWash track mop — a belt washed in real time with 113°F water at 12 N of pressure and squeegeed dry as it runs, plus a separate hot dock wash between runs | Dual spinning pads with auto mop detaching, plus a FlexiArm riser side brush that extends into corners |
| Mop Lift Over Carpet (mm) | 12 mm on carpet detection (Narwal's own figure). Enough to clear a flat rug; not enough for high pile | Sources conflict inside Roborock's own website: the product page says '17mm Mop Lift' and the Saros 10R feature page says '0.87 inches (22mm) Maximum Mop Lifting'. Vacuum Wars separately records 26 mm of AdaptiLift threshold clearance, which is a different measurement again |
| Dock Type & Plumbing | Self-empty plus mop wash and dry. A separate Auto Refill & Drainage version plumbs into a cold supply and a drain; the standard dock does not | Multifunctional Dock 4.0, marketed as 10-in-1: self-empty, mop wash, hot-air dry and refill. The sibling Saros 10 is sold in a plumbed Refill & Drainage version; this one is not |
| Dock Mop Wash & Dry | 176°F (80°C) dock wash for full-chain sterilisation, 104-113°F warm water during the run, 104°F warm-air drying. The dirty-water tank is still emptied and rinsed by hand — no dock here self-cleans that | 176°F (80°C) hot-water mop washing with dirt detection that triggers a re-wash and re-mop, then 131°F (55°C) warm-air drying in 2, 3 or 4-hour cycles. The dirty-water tank is still emptied and rinsed by hand |
| Dock Bags & Running Cost | 2.5 L proprietary bag rated at 120 days, about 3 bags a year — the lowest bag count on this page. Two bags ship in the box. Vacuum Wars notes there is no automatic detergent dispensing, so you top the solution up manually | One proprietary dust bag in the box; retail listings quote 60 days of self-emptying. Roborock's 6-pack that fits the Saros series is $25.59 direct and $31.99 at Abt, so roughly $26-32 a year in bags, plus mop modules and filters |
| Robot Bin Capacity (ml) | 480 ml | Not published on Roborock's US spec page. One third-party spec database lists 400 ml |
| Rated Runtime (and at what setting) (min) | Up to 190 minutes, and Vacuum Wars confirms that figure is the lowest power setting | 180 minutes, and Vacuum Wars confirms that figure is the lowest power setting. They measured 1.8 minutes per battery percent and about 1,389 sq ft per charge against a 1,020 sq ft average |
| Account, Cloud & Camera Privacy | Narwal account required and maps sync to Narwal's cloud. Two cameras on board with in-app remote viewing, so this is a live camera in your home; Narwal states object recognition runs on the robot's own AI chip | Roborock account required and maps sync to Roborock's cloud as well as the robot. Camera on board with in-app remote viewing; independent privacy write-ups report obstacle images are processed on-device and not uploaded by default |

Category Scores
Carpet Cleaning
The Roborock Saros 10R leads clearly here, 8.5 against 8.0 — a 0.5-point margin on embedded-debris and pet-hair pickup from carpet in independent bench tests, plus anti-tangle brush design — not the manufacturer's Pascal claim.. If that is what you are buying for, the Narwal Flow Robot Vacuum and Mop does not close the gap elsewhere.
Hard Floor & Edges
The Roborock Saros 10R leads clearly here, 9.0 against 7.5 — a 1.5-point margin on pickup on hard floor including crevices, edges and corners, and whether the side brush or mop actually extends to the skirting.. If that is what you are buying for, the Narwal Flow Robot Vacuum and Mop does not close the gap elsewhere.
Mopping
The Narwal Flow Robot Vacuum and Mop leads clearly here, 9.5 against 8.5 — a 1.0-point margin on whether the mop scrubs or just drags: pad versus spinning versus washed roller, down-pressure, dried-stain removal and how wet the floor is left. Vacuum-only robots score 0.. If that is what you are buying for, the Roborock Saros 10R does not close the gap elsewhere.
Obstacle Avoidance

If that is what you are buying for, the Narwal Flow Robot Vacuum and Mop does not close the gap elsewhere.
Dock Automation
The Roborock Saros 10R leads clearly here, 9.0 against 8.5 — a 0.5-point margin on how much the dock genuinely does unattended: self-empty, hot-water mop wash, hot-air dry, solution dosing, plumbed refill and drain — minus the jobs it still leaves you.. If that is what you are buying for, the Narwal Flow Robot Vacuum and Mop does not close the gap elsewhere.
Running Cost
The Narwal Flow Robot Vacuum and Mop leads clearly here, 8.0 against 6.0 — a 2.0-point margin on the trap dimension. What the machine costs to feed each year in proprietary bags, mop pads, filters and detergent, and whether a bagless dock lets you spend nothing at all. 10 means it costs nothing to keep running.. If that is what you are buying for, the Roborock Saros 10R does not close the gap elsewhere.
Privacy & Control
The Roborock Saros 10R leads clearly here, 6.0 against 5.0 — a 1.0-point margin on whether an account and cloud are required, where the maps live, whether there is a camera and where its frames are processed, and the brand's actual privacy and security record..

Value
The Narwal Flow Robot Vacuum and Mop leads clearly here, 8.0 against 7.5 — a 0.5-point margin on tested cleaning performance and dock automation against the real street price and the year-one consumables bill..

Pros & Cons
Narwal Flow Robot Vacuum and Mop
Pros
- +The best mopping mechanism here: a track mop rinsed in real time genuinely does not smear dirty water around
- +0% hair tangling and the best battery efficiency Vacuum Wars has measured
- +95 mm tall, so it fits under furniture that stops the Roomba Max 705 dead
- +120-day bag rating means roughly three bags a year, the cheapest bagged dock to feed
Cons
- −12 mm mop lift is mid-table — a thick rug will still get damp edges
- −No automatic detergent dosing, so the 'hands-free' dock still wants manual top-ups
- −List price is $1,499.99 and street has swung from about $799 to $1,049 in 2026 — pay list and you have badly overpaid
- −Two always-on cameras with remote viewing, and Narwal's US privacy documentation is thinner than Roborock's or iRobot's
- −Vacuum Wars notes reported quality-control issues and needs several passes on fine hard-floor debris
Roborock Saros 10R
Pros
- +The only robot here with a perfect 24/24 obstacle score from Vacuum Wars alongside 92% pet-hair pickup — it is the best all-rounder tested
- +Solid-state LiDAR means no turret, so it is 79.8 mm tall and gets under furniture full-dock rivals cannot
- +0% hair tangling against a 39% category average — a real advantage in a long-hair household
- +RTINGS' number-one pick for 2026, and Roborock publishes its accessory prices so running cost is knowable
Cons
- −Roborock cannot keep its own suction claim straight: 19,000 Pa at CES, 22,000 Pa at retail, 18,000 Pa in third-party databases
- −Roborock's own site publishes two different mop-lift figures for this robot, 17 mm and 22 mm
- −The 180-minute runtime is the lowest suction setting; expect far less on carpet at full power
- −No bin capacity published anywhere on Roborock's US spec page
- −Roughly $26-32 a year in proprietary bags, and the dirty-water tank is still a manual rinse
