The Narwal Freo 20 is a roller-mop robot from 2026: its FlowWash roller is flushed with fresh water while it mops, and the dirty water is sucked away at once, so it is not spread over the floor again. It has 31,000 Pa of suction, DualFlow main and side brushes built against hair wrap, obstacle recognition with two cameras and TwinAI that, according to Narwal, knows more than 300 types of household object, and it takes double thresholds of up to 4 centimetres. The station washes the roller in water of up to 100 degrees, dries it with air of up to 60 degrees, refills the robot and holds up to 120 days of dust.
On paper it matches the Narwal Flow 2, which TechRadar and Vacuum Wars tested, in several places: the same 31,000 Pa, a self-rinsing roller, a two-camera obstacle system, a wash of up to 100 degrees and 120 days of dust. Our specifications do not show whether it doses detergent or can be connected to the water supply, both of which the Flow 2 can.
None of our test sources has measured the Freo 20. Whether it avoids the Flow 2's weak spots in the tests, dried stains and edges, is not yet known. At 95 millimetres the robot is of average height, and our specifications list no battery or run time. Anyone who wants a Narwal with a roller mop and camera recognition on the strength of test results can look at the Flow 2.
Based on the maker's specifications and our price data; none of our test sources has tested this model.

Suction in pascal, as the maker measures it. More pascal helps on carpet, but it says little about how well the robot picks grit off a hard floor.

The side brush swings out in a corner or along a kickboard, so the dust there is swept in too. On this model: Assumed, not a stated fact: the maker's full specification does not name it, so we take it as no.

Yes. The station empties the robot’s dust bin after every run. The 2.4 l dust bag in the station lasts up to 120 days, the maker says.
Yes. The station washes the mop itself, with water at 100 °C. It then dries the mop with warm air.
It works with Alexa and Google Assistant.
Thresholds up to 40 mm, the maker says. It has no climbing system for higher thresholds. Measure your own thresholds: the ones to a bathroom or balcony are often higher.
The robot is 9.5 cm tall, so it fits under furniture with at least 10 cm of clearance. It has no turret on top.
Yes, the maker says. The brush guides hair to the side instead of winding it round the roller. The maker says it also recognises a pet’s accident and drives round it.
