Flow 2
Narwal's flagship: 31,000 Pa, a rolling track mop rinsed with fresh water as it goes and washed at 100 °C in the dock, a pressure plate for carpet, dual 1080p cameras with no turret, and a 7,000 mAh battery, for €1,099.

Our verdict
The Flow 2 is Narwal's answer to the turret-free flagships, and it argues its case with the mop. A FlowWash track mop rolls under a stream of fresh water while it works, so it does not push yesterday's dirt around, and the dock finishes the job at 100 °C with warm-air drying and automatic detergent. Suction is 31,000 Pa, second only to the Saros 20 here, and a pressure plate seals the deck to the carpet for what Narwal calls 4.2 times the pull. The body is 95 mm tall because positioning and obstacle avoidance both come from two 1080p cameras and a 10 TOPS chip rather than a LiDAR turret, and it crosses a 40 mm threshold. What Narwal does not publish is the list Roborock also keeps short: no bin or tank capacity, no runtime, no weight, no map count, and no word on how camera-only positioning behaves in a dark room. The mop lifts 10 mm over carpet, which is on the low side, and the price is flagship money.
Pros
- Rolling track mop rinsed with fresh water while cleaning, washed at 100 °C and dried in the dock
- 31,000 Pa with a pressure plate that seals to carpet
- 95 mm tall with no turret; crosses 40 mm thresholds
- Dual 1080p cameras and a 10 TOPS chip for obstacles down to 5 mm
- 7,000 mAh battery, 120 days of dust storage, under 56.5 dB
Cons
- Positioning by cameras alone; Narwal makes no low-light claim
- Mop lifts only 10 mm over carpet
- No bin, tank, runtime, weight or map count published
- €1,099, flagship money without a LiDAR fallback
Best for
- Homes with hard floors and sticky spills, where a roller beats pads
- Low furniture that a turret cannot get under
- Owners who want the dock to wash, dry and dose detergent itself
Not recommended for
- Dimly lit flats, until Narwal says how the cameras cope
- Deep carpet, where a 10 mm lift is marginal
- Buyers who need a published runtime or bin size
