The Narwal Flow 2 is Narwal's flagship with two HD cameras and an AI processor that, according to the maker, recognizes a near-unlimited range of objects down to keys and wallets, a self-refreshing roller mop, 31,000 Pa of suction and a station that washes in boiling-hot water, dries with hot air, doses detergent, can be plumbed in and makes the bag last about 120 days. TechRadar names it the best for obstacle avoidance; Vacuum Wars ranks it 17th of 20.
TechRadar watched it double back mid-run to re-mop a dirty entryway, dodge obstacles at top-tier level and even name them in the app, with suction exceeding their top pick. Vacuum Wars measured 20 of 24 obstacles avoided, above-average route efficiency despite an unusual pattern, 84 percent of the sand out of carpet, excellent pet hair pickup and not a single wrap in the long-hair test. An editor then used it for three months in a family with a heavily shedding dog and was happy with mopping, hair and obstacles.
The criticism: in the lab, mopping of dried stains scored only 68 points against a 108 average, TechRadar found edges and baseboards less clean, the robot is too tall for some cabinets and users reported flaky maps and connections in the app, which Vacuum Wars confirmed in daily use. The side brush does not extend. Anyone wanting the smartest obstacle recognition and a complete station, and willing to live with the app, gets a strong package.

Narwal Flow 2 specifications
The numbers that matter first, then every fact by group. As published by the maker or the store we read it from.
The side brush swings out in a corner or along a baseboard, 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.
no (assumed)
Suitable for pet hair
When it matters
Dogs and cats that shed.
Long-haired pets, whose hair wraps around a brush.
Without pets, ordinary hair and dust need nothing special.
Source: derived, no source of its own · checked on Oct 2
Whether the robot copes with pet hair: a brush that hair does not wind around and a dock that empties the bin for you. Where the maker does not say so itself, we read it from those two.
yes
Mopping6 facts
Mop type
When it matters
Homes with a lot of hard floor that you want mopped, not just wiped.
Dried-on dirt in a kitchen, which spinning pads or a roller scrub off better than a dragged cloth.
If you only vacuum, the mop’s build decides nothing.
The robot leaves the mop at the dock before it vacuums a carpet, so the carpet never gets wet. On this model: Assumed, not a stated fact: the maker's full specification does not name it, so we take it as no.
no (assumed)
Mop refreshed while mopping
When it matters
Large hard floors, where a mop that is never rinsed spreads dirt around.
Kitchens with sticky spills.
In a small home the mop does not get dirty enough in one run for it to matter.
The robot returns to the dock during a run to rinse the mop, instead of pushing dirty water around. On this model: from the maker's product text, not from a specification table.
yes
Water tank in the robot
When it matters
Large hard floors mopped in one go.
A robot whose dock does not refill it during a run.
With a dock that refills the robot during the run, the tank’s size hardly matters.
The dock collects dust in a bin instead of a disposable bag. No bags to buy, but you empty it yourself. On this model: Assumed, not a stated fact: the maker's full specification does not name it, so we take it as no.
The dock can be connected to the tap and the drain, so you never fill or empty a tank. It does need a connection nearby. On this model: from the maker's product text, not from a specification table.
yes
Dock size (w × d × h)
When it matters
A small hallway or a niche where the dock has to fit.
Placing the dock under a cabinet or a counter.
Along an open wall with room to spare it decides little.
How the robot maps your home and follows that map. Lidar measures with a laser and works in the dark, a camera looks along and recognizes more. On this model: from the maker's product text, not from a specification table.
