Narwal Flow review
Narwal's roller-mop robot below the Flow 2: 22,000 Pa, a track mop scraped and rinsed 110 times a minute, 45 °C water at 1.22 kg of pressure, 120 days of dust storage, two cameras and no turret.

Our verdict
The Flow carries the Flow 2's mop mechanism at a lower price. The same track mop is scraped and rinsed 110 times a minute from 16 nozzles as it works, pressed down at 1.22 kg and fed 45 °C water, and two RGB cameras with an AI chip handle obstacles and positioning without a LiDAR turret, so the body is 95 mm tall. The mop and the side brush extend to the wall, and it climbs 40 mm ledges. You give up suction, 22,000 Pa against the Flow 2's 31,000, the carpet pressure plate and part of the dock: Narwal's page lists hot-water washing and 120 days of dust collection but nothing about drying. On carpet the track mop lifts 12 mm, once Carpet Mode is on in the app. The battery is 6,400 mAh, 'Hey Nawa' takes voice commands, and an optional self-fit kit handles refilling and draining. Bin, tank, runtime, weight and noise are not published.

In detail
Suction and brushes
The manufacturer rates the suction at 22,000 Pa. That is about the middle of the field. The main brush is the tangle-resistant type, with one side brush. On carpet the suction rises automatically.
Mopping
Mop system: washed roller. It lifts the mop 12 mm over carpet. The mop swings out to reach along walls.
Navigation and obstacles
It navigates by camera SLAM and avoids obstacles with twin-camera AI. It climbs thresholds up to 40 mm. That is more than 66% of the 71 robot vacuums with a published figure. No-go zones can be drawn in the app.
The dock
The dock empties the bin, washes the mop and refills the water tank. The dust bag lasts about 120 days.
Battery, charging and noise
The manufacturer publishes neither a runtime nor a noise figure.
