The Narwal Flow 2 and Dreame Matrix10 Ultra are flagship robot vacuums with similar quoted suction but different mopping systems and docks. The Ambient has lab-tested the Narwal, while its Dreame comparison relies on manufacturer specifications and a sister-site review, so a direct test is still pending.
The Narwal Flow 2 and Dreame Matrix10 Ultra use different mopping systems: Narwal has a heated roller mop, while Dreame has spinning pads and a dock that swaps among three pad types. The Ambient reports strong stain results from its lab tests of the Flow 2, but says it has not tested the Matrix10 Ultra itself, so a direct performance comparison is not available.
Both manufacturers list suction at about 30,000Pa: Narwal quotes 31,000Pa for the Flow 2 and Dreame lists 30,000Pa for the Matrix10 Ultra. The Ambient’s lab testing found the Flow 2 removed dried coffee and red-wine stains in one pass and mud in two. Dried ketchup required pretreatment with kitchen cleaner before it came off. Those results are specific to the Flow 2; the publication says it has not yet run the same tests on the Dreame.
The central difference is the mop system. The Flow 2’s FlowWash track-style roller receives water heated to 60°C while cleaning and applies 12 newtons of pressure, according to the comparison. Its dock washes the roller at 100°C. The Matrix10 Ultra uses two spinning pads, also washed by its dock at 100°C, and Dreame says the station can automatically choose among thermal, nylon and sponge pads for different areas.
The machines also differ in carpet handling and navigation. Narwal lists a 10mm mop lift; the Matrix10 Ultra lifts pads 10.5mm and can detach them on long-pile carpet. The Dreame’s retractable laser sensor allows a listed height of 89mm, compared with 95mm for the Flow 2. Dreame says its AI camera recognises more than 240 object types. The Ambient reports the Flow 2 avoided shoes, cables and simulated pet mess in its tests.
Mopping Systems and Features Differ
The comparison sets out differences in mop design, carpet handling and dock automation, alongside similar manufacturer-listed suction figures. The Flow 2 has results from The Ambient’s own tests, including tests on dried stains. Dreame says its dock can automatically swap among three pad types for different areas. The comparison does not establish how those pads perform relative to Narwal’s roller.
Price and availability also differ by market. Dreame’s UK store listed the Matrix10 Ultra at £999, discounted to £799 at the time of the report. Narwal listed the Flow 2 at $1,499.99 in the United States, discounted to $1,299.99, and €1,299 in Europe; it had not confirmed a UK price. These are market-specific listed prices, not a like-for-like comparison across currencies.
The published specifications give different figures for obstacle clearance. The Flow 2 reached a 3cm single threshold or 4cm double threshold, while Dreame lists up to 4.2cm for a single step or 8cm for a double threshold. The Matrix10 Ultra can detach its pads on long-pile carpet, while the Flow 2 lists a 10mm mop lift. Actual results may depend on the shape and surface of an obstacle or rug.

What the Published Tests Cover
The Ambient says it tested the Narwal Flow 2 in its Home Technology Lab using its regular carpet, hard-floor, stain and obstacle tests. It found the robot cleared flour from carpet in two passes and collected dust from hard floors in one vacuum-only run. The publication also reports that the Flow 2 cleaned its lab on one charge, even when set to make three passes; Narwal rates its 7,000mAh battery for up to 190 minutes.
For the Dreame Matrix10 Ultra, The Ambient relied on Dreame’s specifications and a review by its sister publication, Trusted Reviews. The comparison says Dreame does not disclose battery capacity or runtime. The two docks both offer automatic emptying, 100°C mop washing, hot-air drying and detergent dosing, but their capacities and cleaning-solution systems differ. Narwal lists a 2.5-litre dust bag rated for up to 120 days; Dreame lists a 3.2-litre bag rated for up to 100 days.
“We’ll update this comparison once we’ve tested it.”

The Missing Direct Dreame Test
The key limitation is that The Ambient has not tested the Matrix10 Ultra using the same procedures as the Flow 2. The available comparison therefore cannot establish which model performs better on the same stains, carpet, obstacles or cleaning schedule. Dreame’s claim about recognising more than 240 object types is not independently verified in the article.
Some specifications are also unavailable or are manufacturer estimates. The source does not provide Dreame’s battery capacity or rated runtime, and the quoted hands-free operating periods depend on use. Narwal has not confirmed UK pricing in the report. The comparison’s price listings are time-sensitive, and the discounted Dreame price may change.
A Direct Test Is Still Pending
The Ambient says it plans to update the comparison after testing the Dreame Matrix10 Ultra. That test would allow a closer assessment of cleaning performance, obstacle avoidance and carpet handling against the Flow 2 under comparable conditions. Until then, the comparison draws on the published Flow 2 lab results and Dreame’s specifications and a third-party review.
Shoppers can check current regional prices and compare the models’ stated features with their flooring, rugs, thresholds and preferred dock functions. The available testing does not establish a winner, and direct comparative results remain unavailable.
Key Questions
Which robot vacuum has stronger suction?
The listed figures are close: 31,000Pa for the Narwal Flow 2 and 30,000Pa for the Dreame Matrix10 Ultra. These are manufacturer specifications, and they do not by themselves show which robot cleans better in practice.
Which model has been tested by The Ambient?
The Ambient tested the Narwal Flow 2 in its Home Technology Lab. It has not yet tested the Matrix10 Ultra using the same procedures, so the comparison is not a direct head-to-head lab test.
What is the main difference in their mopping systems?
The Flow 2 uses a heated track-style roller that is cleaned as it works. The Matrix10 Ultra uses spinning pads and a dock that Dreame says can automatically swap among three pad types.
Which model may suit a home with thick carpet?
The Matrix10 Ultra is specified to detach its pads on long-pile carpet. The Flow 2 lifts its roller by 10mm but cannot leave the mop at the dock. The comparison does not include a direct test of both models on the same thick carpet.
How much do the two robot vacuums cost?
At the time of The Ambient’s report, Dreame listed the Matrix10 Ultra in the UK for £999, or £799 on discount. Narwal listed the Flow 2 at $1,299.99 on sale in the United States and €1,299 in Europe; UK pricing was not confirmed.
