Side-by-Side Comparison
| Spec | Roborock Qrevo Curv | Narwal Flow Robot Vacuum and Mop |
|---|---|---|
| Price | $849.99 | $899.99 |
| Release Year | 2024 | 2025 |
| Claimed Suction (Pa) | 18,500 Pa on Roborock's own product page. For scale on how soft these numbers are: Roborock announced the Saros 10R at 19,000 Pa at CES 2025 and now sells the same robot as 22,000 Pa on Amazon and Best Buy | 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 |
| Independent Test Result | Vacuum Wars rates obstacle avoidance as the Qrevo line's weak spot next to ECOVACS and eufy; the Curv's successor, the CurvX, sits at #17 in their 2026 Top 20. Reactive AI here recognises 62 object types against 108 on the Saros 10R | 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 |
| Navigation & Obstacle Avoidance | PreciSense LiDAR plus Reactive AI camera-based obstacle recognition, 62 object types, with an in-app video-call and pet-view feature | 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 |
| What the Maker Promises About Pet Waste | Roborock lists pet waste among the objects Reactive AI is trained on. There is no published replacement guarantee if it drives through it | Narwal lists pet waste among the objects the dual-camera system recognises but publishes no replacement guarantee if it fails |
| Mop System | Dual spinning pads with adaptive down-pressure and an extending arm that pushes the pad out to skirting boards | 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 |
| Mop Lift Over Carpet (mm) | 17 mm on carpet detection — Roborock's own figure, and it is printed in the Amazon listing title. High enough to genuinely clear a low-pile rug | 12 mm on carpet detection (Narwal's own figure). Enough to clear a flat rug; not enough for high pile |
| Dock Type & Plumbing | Multifunctional Dock 3.0 — self-empty, mop wash, hot-air dry, refill from onboard tanks. No plumbed refill or drain on this model | 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 |
| Dock Mop Wash & Dry | 167°F (75°C) hot-water mop washing, then 113°F (45°C) warm-air drying, plus a dock self-clean cycle for the washboard. The dirty-water tank is still yours to empty and rinse | 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 |
| Dock Bags & Running Cost | Proprietary Roborock bag rated at about 7 weeks. Roborock sells the 6-pack that fits this dock at $25.59 direct and Abt lists it at $31.99, so roughly $26-32 a year in bags. Add mop cloths for the Curv/Edge series at $20.99 for four, a main brush at $22.99 and side brushes at $11.19 a pair | 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 |
| Robot Bin Capacity (ml) | Not published on Roborock's US Qrevo Curv page | 480 ml |
| Rated Runtime (and at what setting) (min) | Roborock does not publish a minute figure on the US Qrevo Curv page. The battery is 6,400 mAh, the same cell as in the Saros 10R which Roborock rates at 180 minutes on its lowest setting | Up to 190 minutes, and Vacuum Wars confirms that figure is the lowest power setting |
| Account, Cloud & Camera Privacy | Roborock account required and maps sync to Roborock's cloud as well as living on the robot. There is a camera with in-app remote viewing; independent privacy write-ups report Roborock processes obstacle images on-device and does not upload them by default. 'Hello Rocky' voice control works with the internet down | 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 |
| Warranty | 12 months | 12 months |
| Colors | Black, White | White, Black |

Pros & Cons
Roborock Qrevo Curv
Pros
- +17 mm mop lift genuinely clears a low-pile rug, where the ECOVACS X11's 10 mm does not
- +AdaptiLift raises each wheel independently for a 4 cm threshold — it goes places the flat-chassis robots cannot
- +Offline 'Hello Rocky' wake word means basic control survives an internet outage
- +Roborock publishes real accessory prices, so the running cost is knowable before you buy
Cons
- −Reactive AI recognises 62 object types against 108 on Roborock's own Saros 10R — obstacle avoidance is the Qrevo line's known weakness
- −Roborock publishes neither a runtime nor a bin capacity on the US Qrevo Curv page
- −Roborock's own site quotes a 1-year limited warranty; a widely cited warranty comparison claims Roborock gives 2 years, so check your invoice
- −Roughly $26-32 a year in proprietary bags, against $0 for the bagless Shark and ECOVACS docks
- −$849.99 direct against a $1,599.99 list price that nobody has paid in a long time
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
