Robot Vacuums / Narwal
Narwal Flow Robot Vacuum and Mop
The best mop in the category on a track that rinses itself — buy it on discount, never at list.
Overall score 7.8/10
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
Narwal Flow Robot Vacuum and Mop review: what the specs say
The best mop in the category on a track that rinses itself — buy it on discount, never at list. At $899.99, Narwal's 2025 model sits in the middle of the range — the robot Vacuums we compare run from $139.99 to $1,399.99. It scores 7.8/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.
Its strongest showing is Mopping at 9.5/10 — 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.. The weakest is Privacy & Control at 5.0/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.
Worth knowing before you buy: 12 mm mop lift is mid-table — a thick rug will still get damp edges; and no automatic detergent dosing, so the 'hands-free' dock still wants manual top-ups. Every specification on this page comes from Narwal's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.

Full Specifications
| 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 |
| 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 |
| 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 |
| 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 |
| 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 |
| Mop Lift Over Carpet | 12 mm on carpet detection (Narwal's own figure). Enough to clear a flat rug; not enough for high pile mm |
| 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 |
| 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 |
| 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 |
| Robot Bin Capacity | 480 ml ml |
| Rated Runtime (and at what setting) | Up to 190 minutes, and Vacuum Wars confirms that figure is the lowest power setting min |
| 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 |
| Connectivity | Wi-Fi (Narwal app), Alexa, Google Assistant, Siri Shortcuts |
| Material | Plastic; Narwal publishes no housing material |
| Warranty | 12 months |
