The Narwal Flow 2 and Dreame Matrix10 Ultra are premium robot vacuums with similar stated suction but different mopping and dock designs. The Ambient tested the Flow 2, while its comparison of Dreame relies on manufacturer specifications and a review by Trusted Reviews; a direct test is still pending.
The Narwal Flow 2 and Dreame Matrix10 Ultra take sharply different approaches to flagship robot cleaning, according to a new comparison from The Ambient: Narwal emphasizes a heated roller mop, while Dreame uses spinning pads and a dock that swaps pad types automatically. The comparison is not a head-to-head test: The Ambient tested the Flow 2 but says it has not reviewed the Matrix10 Ultra, so some conclusions about Dreame rely on specifications and a Trusted Reviews review.
Both machines list suction around 30,000Pa: Narwal specifies 31,000Pa for the Flow 2 and Dreame lists 30,000Pa for the Matrix10 Ultra. The Ambient’s lab tests found that the Flow 2 removed dried coffee and red wine in one pass and mud in two; dried ketchup required pretreatment with kitchen cleaner. Those results apply to the Narwal, not to a comparison against Dreame.
The key design difference is the mop. Narwal’s FlowWash system uses a continuously cleaned fabric roller, with water heated to 60°C during mopping and pressure of 12N. Dreame uses two spinning pads, washed by its dock in 100°C water. The Matrix10 Ultra dock can automatically switch among three pad types, intended for different rooms and messes. The Ambient describes Dreame’s arrangement as more flexible, but says it has not yet tested how its pads perform on stains.
Both docks automatically empty the robot, wash and hot-air dry the mop, and dose detergent. Narwal says its 2.5-litre dust bag can last up to 120 days; Dreame rates its 3.2-litre bag for up to 100 days. These are manufacturer claims, not independently verified durations in the comparison.
Choosing Between Mop Designs
For buyers, the difference is less about the nearly matched stated suction figures than about floor types and how much automation they want. The Flow 2’s tested roller performance offers some evidence for households focused on hard floors and dried-on stains. Dreame’s three-pad system aims to tailor cleaning by room, but its real-world performance against the Narwal remains untested by The Ambient.
Carpet clearance may also matter. The Flow 2 lifts its roller by 10mm, which the report says should suit short-pile rugs but may not keep the mop clear of deeper carpet. Dreame lifts its pads by 10.5mm and detaches them on long-pile carpet, according to its specifications. That gives the Matrix10 Ultra a stated design advantage for thick rugs, though buyers do not yet have a direct test from The Ambient to confirm how it works in practice.

Prices and Test Coverage
The comparison reports different regional prices, so the models cannot be compared on price without accounting for market and currency. Dreame’s UK store listed the Matrix10 Ultra at £999, discounted to £799 when the report was written. Narwal listed the Flow 2 at $1,499.99 in the United States, discounted to $1,299.99, and at €1,299 in Europe; Narwal had not confirmed UK pricing.
The Ambient says it tested the Flow 2 in its Home Technology Lab using its regular carpet, hard-floor, stain and obstacle tests. For the Matrix10 Ultra, it used Dreame’s published specifications and a review by its sister site, Trusted Reviews. The outlet says it plans to update the comparison after testing the Dreame model.
“The more useful difference between them is how they mop, how well they can navigate, and how easy they are to use.”

Dreame’s Performance Still Untested
The main gap is the absence of a direct, shared test of the two robots. The Ambient has not assessed the Matrix10 Ultra in its lab, so its pad cleaning, navigation and obstacle avoidance have not been compared with the Flow 2 under the same conditions. Dreame’s claim that its system recognizes more than 240 object types is presented as a company specification, not an independent test result.
Some practical details are also unavailable in the supplied comparison. Dreame does not disclose a battery capacity or runtime there, and Narwal has not confirmed UK pricing. The dust-bag duration figures are company estimates, while actual maintenance intervals will depend on use and home conditions.
A Direct Test Is Pending
The next relevant development is The Ambient’s planned test of the Matrix10 Ultra. The outlet says it will update its comparison after testing, which should add independent evidence on Dreame’s mopping, navigation and cleaning performance against the Flow 2. Until then, buyers can compare stated features and regional prices, but should treat the models’ relative real-world performance as unsettled.
Key Questions
Which robot vacuum performed better in The Ambient’s tests?
The Ambient tested only the Narwal Flow 2 in its lab. It reported that the Flow 2 removed dried coffee and red wine in one pass and mud in two; it has not yet tested the Dreame Matrix10 Ultra under the same conditions.
What is the main difference between their mops?
The Flow 2 uses a continuously cleaned, heated track-style roller mop. The Matrix10 Ultra uses spinning pads, and its dock automatically swaps among three pad types intended for different rooms and cleaning needs.
Which model is designed for homes with thick carpets?
Dreame says the Matrix10 Ultra lifts its pads and detaches them on long-pile carpet. The Flow 2 lifts its roller by 10mm, which The Ambient says may not be enough to clear deeper carpet. A direct comparison test is still pending.
How much do the two models cost?
At the time of The Ambient’s report, the Matrix10 Ultra was listed at £799 on sale from £999 in Dreame’s UK store. The Flow 2 was listed at $1,299.99 on Narwal’s US store after a discount, and €1,299 in Europe. Narwal had not confirmed UK pricing.
