Narwal Flow 2 Review: The Rolling Track Mop That Sets the Bar for Hands-Free Floors
31,000 Pa suction, a self-rinsing track mop with hot water and a dock that runs itself for months, wrapped in an app that takes patience.
The Narwal Flow 2 is the brand's flagship robot vacuum and mop, and the FlowWash rolling track mop is what separates it from everything else: instead of dragging a pad, a belt continuously washes itself with 140 F water while scrubbing at up to 12 N of pressure. Owners coming from Roborock, Roomba and Ecovacs flagships describe it as a clear step up on mopping, with dried spills coming off in a single pass and no streaking. Suction is class leading at 31,000 Pa, the dual-camera VLM navigation avoids cables and pet bowls reliably, and the base station handles hot-water washing, warm-air drying and up to 120 days of dust collection. The main complaint is the app: the mapping and room editing take real effort to get right.

Who is the Narwal Flow 2 for?
This is for people who want floor cleaning to genuinely disappear from the chore list and are prepared to pay flagship money for it. The rolling track mop, 31,000 Pa suction and the AI-adaptive station together cover vacuuming, scrubbing, mop washing, drying and emptying without intervention. Owners running it across hardwood, tile and area rugs report it handles the transitions without getting stuck, and the dual tangle-free roller plus auto de-tangling side brushes are repeatedly credited with surviving long hair and shedding dogs without manual unwrapping.
What buyers love
Mopping dominates the praise. Owners who have used several premium robots describe the FlowWash belt as the best mopping system they have tried, because it keeps presenting a clean, hot surface to the floor rather than pushing dirty water around. Suction gets the same treatment: several reviewers say it lifts pet hair and fine dust from carpet better than their stick vacuum. Mapping is fast and accurate, obstacle recognition through the dual 1080p cameras avoids cables and shoes down to fractions of an inch, and it is noticeably quiet outside the maximum suction mode. Build quality comes up again and again, with owners describing a heavy, premium feel that looks like furniture rather than an appliance.
What to know before you buy
The app is the recurring complaint. Getting the floor plan split into the right rooms takes merging, splitting and patience, and several owners say it took weeks of regular use before the settings made sense. A handful report the robot failing to find its way back to the dock, and one reviewer had trouble pairing over Matter despite the certification. It is also physically large and heavy, so the dock needs real floor space. And while the station is maintenance free for months at a time, this is a premium purchase: the price is the biggest barrier for most shoppers.
Is the Narwal Flow 2 worth it?
If mopping quality is the reason you are buying a robot, this is currently the most convincing execution of the idea, and the suction figure means you are not trading vacuuming away to get it. It is Matter certified, so it slots into Apple Home, Alexa, Google Home and SmartThings without a bridge, and the 2.5 L dust bag means you can ignore the dock for months. Budget buyers and people who want a simple app should look at a mid-range model instead; everyone else gets a genuine flagship.
Frequently asked questions
Is the Narwal Flow 2 Matter certified?
Yes. It is listed as Flow 2 in the CSA Matter certified product database, so it can be added to Apple Home, Amazon Alexa, Google Home and SmartThings as a Matter device, alongside Narwal's own app.
How is the FlowWash mop different from spinning pads?
Instead of two rotating discs, a rolling track presses a belt against the floor and rinses it continuously with hot water, scraping the dirty water into a sealed tank. That means the surface touching your floor is always clean, which is why owners report it removing dried spills in one pass.
How often do I need to touch the base station?
The station empties the robot into a 2.5 L dust bag rated for up to 120 days, washes the mop with 113 to 176 F water and dries it with warm air. Day to day you only top up the clean water tank and detergent.
Does it handle carpet?
Yes. Pressurized CarpetFocus offers four carpet modes, including avoiding carpet entirely, crossing it, boosting suction on it, or vacuuming and mopping, and the mop lifts 12 mm when it detects a rug.
How long does a full clean take?
Narwal quotes roughly 115 minutes to sweep a 150 square metre home, about 140 minutes to mop it, and around 160 minutes in the simultaneous hosting mode. Amazon lists 275 minutes of battery runtime.
