Narwal Flow 2 Review: Hot-Water Mopping Robot Vacuum

As someone who already lives with a Narwal robot at home, the arrival of the brand's new flagship caught my attention right away. The Narwal Flow 2 was unveiled at CES 2026 and is being positioned as the company's most capable cleaning robot yet. It pairs a continuously rolling track mop with 31,000 Pa of suction and a base station that all but takes care of itself. But what do all those claims actually mean day to day? Here's a full, honest look — the good and the not-so-good.

What is the Narwal Flow 2? Quick overview

The Narwal Flow 2 is a premium robot that both vacuums and mops. Its biggest differentiator is that instead of the usual spinning disc pads, it uses a continuously moving "track" mop belt. That belt is rinsed in real time with flowing water as it cleans, so rather than smearing dirt around, it keeps meeting the floor with a fresh surface. Add 31,000 Pa of suction, dual-camera AI navigation and a station that runs itself for up to 120 days, and you get a genuine "set it and forget it" machine.

The headline features: a self-cleaning FlowWash mop that washes with hot water, TwinAI obstacle avoidance with dual 1080P cameras, a 7,000 mAh battery, quiet operation under 56.5 dB, and an optional automatic water refill and drainage system.

FlowWash: the self-cleaning hot-water mop

The classic problem with robot mops is simple: the pad gets dirty, and then you drag that dirty pad across the whole house. The Narwal Flow 2 tackles this by continuously washing the belt as it rolls — pulling dirt inward and always presenting a clean surface to the floor. Because it mops with warm water (around 45–60 °C), it also breaks down dried stains and grease more easily than a cold, damp pad.

Edge cleaning is thoughtfully handled too: the mop can extend toward the wall, and the robot gets to within about 5 mm of baseboards. That noticeably reduces the "dirty strip left along the edges" issue most robots suffer from. When it detects carpet, the mop lifts 12 mm so it never gets the carpet wet.

31,000 Pa suction and carpet performance

On paper, 31,000 Pa is among the strongest in its class. In practice, that power shows up most when pulling crumbs off hard floors and, especially, lifting embedded dust and pet hair from deep in carpet fibres. When carpet is detected, a pressure plate seals the brush inlet and instantly boosts suction, then the robot makes a second reverse pass to loosen anything trapped beneath the pile.

If you have a cat, a dog, or — like me — a feathery pet at home, this is where the difference really lands. The anti-tangle roller brush is designed so long hair doesn't wind around it and lock the unit up. To be fair, though, very long hair can still gather at the outer edge of the brush now and then, so an occasional manual check is worth it.

TwinAI obstacle avoidance and navigation

The Flow 2 "sees" its surroundings with dual 1080P cameras and a 10 TOPS AI chip. It detects and avoids typical household hazards — cables, chair legs, toys — with millimetre-level precision, spotting objects as small as 5 mm. Thanks to its Narmind Pro vision-language model, it gets to know your home better over time and adapts its route accordingly.

It can climb thresholds up to 4 cm and stands just 9.5 cm tall, which helps it slip under furniture and move between rooms. One caveat that comes up in owner feedback: the map-editing screen doesn't show furniture or the spots where the robot got stuck, so drawing no-go zones can take some trial and error at first. It's the kind of thing firmware updates typically improve.

The maintenance-free base station

The station is the most reassuring part of this machine. When the robot finishes, it returns and handles everything itself: it washes the mop belt with roughly 100 °C hot water, dries it with warm air to prevent mould and odour, empties debris into a 2.5 L bag, and auto-doses detergent. In a pet-free home, that bag can last up to 120 days.

You can also add the optional automatic water refill and drainage system, which removes manual tank filling entirely. Just know upfront that it needs a nearby water supply, drainage and a power outlet — it's a small plumbing job, so plan for it.

App, voice control and smart home

Through the Narwal app you get multi-level 3D mapping, room-by-room cleaning order, no-go zones and carpet-type settings. There are also nice touches like baby-care and pet-care modes, scheduled cleaning and a child lock. Voice control works with Alexa, Siri and Google Assistant, and there's a built-in voice assistant called NarGPT.

One privacy detail stands out: the AI data is processed locally on the device rather than uploaded to the cloud — a considerate approach you don't see often enough in smart-home gear.

Specifications table

Narwal Flow 2 price and availability

Narwal already has an official presence in many markets, with its Freo line widely available, so the Flow 2 is likely to reach more regions over time. If you want a price/performance benchmark, current flagships like the Narwal Freo Z10 Ultra make a reasonable reference point.
