Narwal Flow
Narwal's 2025 flagship that introduced the FlowWash rolling track mop, pairing 22,000Pa suction and a low 3.7-inch embedded-LiDAR body with a mop that rinses itself with 176°F hot water as it cleans.
Specifications
Features

Owner Insightssummarized from Reddit and owner forums
The Flow is Narwal's 2025 flagship and the machine that made track mops a thing. Ask Reddit which robot actually mops rather than smears, and this is the default answer — "hands down the best robot mop" comes up over and over. The wide roller pad gets washed with hot water while it works, presses down with real force, and swings out to reach edges. Nobody seriously disputes the mopping. Everything after that is where the arguments start.
Day to day, hard-floor owners love it: quiet, fast, great obstacle avoidance, and floors that genuinely look scrubbed. But the vacuum side is a step behind Roborock and Dreame flagships — fine for everyday debris, weak on thick carpet — and it's a water hog, so the tank version means constant refills. The app is dense and buggy, mapping struggles with open layouts and won't let you split rooms cleanly, and it has a habit of jamming itself under low cabinets. The plumbed version fixes the water problem but its pump-priming process has flooded floors, with little help from Narwal support.
At $1,499 list nobody should buy it — but it launched with $1,099 presale pricing and has sold on Amazon around $1,049, where the value case gets real. It's the right robot for tile- and hardwood-heavy homes where mopping is the whole point. It's the wrong robot for high-pile carpet or heavy dog hair — testers explicitly steer those homes elsewhere. Owners who've run it against a Roborock Saros 20 keep reaching the same split decision: "Narwal is best mop," but the Saros is the one that never needs rescuing.
What owners like
- +Widely called the best robot mop on the market — the track mop is washed in real time with 113°F water so it never drags dirty water across the floor
- +EdgeReach extends the mop outward to actually hit baseboards and corners, which spinning-pad robots miss
- +Exceptional on tile — one tester called its performance on flat and pitted tile "unparallelled"
- +Strong obstacle avoidance that reliably steers around toys, cables, and clutter
- +Quieter than competing flagships and runs longer per charge — owners note it's faster through a house too
- +Carpet mode drops a brush cover to concentrate suction up to 22,000 Pa and lifts the mop so rugs stay dry
Common complaints
- −Vacuuming lags flagship rivals — multiple testers called it mediocre, and one high-pile carpet owner said "the vacuum just couldn't handle the thickness"
- −Drinks a ridiculous amount of water — non-plumbed owners refill the tank constantly, sometimes mid-run in bigger homes
- −Wedges itself under low furniture — one owner's unit got stuck under a cabinet so badly it broke
- −App is overloaded and buggy — and it won't let you split rooms properly when the map comes out wrong
- −Small onboard dustbin fills fast in larger or pet-heavy homes
- −The plumbing-kit version needs pump priming that can flood, and owners say Narwal offers no real guidance on doing it right
- −TechRadar's verdict sums up the pattern: "superb cleaning let down by software quirks" — pathing errors show up in certain layouts

Is the mopping really that much better than Roborock or Dreame?
How weak is the vacuuming, honestly?
How bad is the water consumption?
Should I buy the Flow or the Flow 2?
Does it get stuck a lot?
What's a fair price?
