Flow
The roller-mop Narwal at €699: 22,000 Pa, a track mop scraped and rinsed 110 times a minute, 45 °C water at 1.22 kg of pressure, a self-emptying dock for 120 days, dual-camera obstacle avoidance and no turret.
Review method: Specification analysis
Our verdict
The Flow is the Flow 2's mechanism at two-thirds of the price. The same rolling track mop is scraped and rinsed 110 times a minute from a 16-nozzle feed while it works, pressed down at 1.22 kg and fed 45 °C water, and the same pair of RGB cameras with an AI chip handles obstacles and positioning without a LiDAR turret, which keeps the body at 95 mm. The mop and the side brush extend to the wall, and it climbs 40 mm ledges. What you give up is suction, 22,000 Pa against 31,000, the pressure plate for carpet, and part of the dock: Narwal's page lists hot-water washing and 120 days of dust collection and says nothing about drying or about lifting the mop over carpet. The battery is 6,400 mAh, there is a 'Hey Nawa' voice assistant, and an optional plumbing kit takes over refilling and draining for €300 more. Bin, tank, runtime, weight and noise are not published.
