The Narwal Flow 2 and Dreame Matrix10 Ultra are high-end robot vacuums with similar quoted suction but different mopping systems. The Ambient has tested the Narwal, while its comparison of the Dreame relies on specifications and a sister-site review; a direct test is still pending.
The Ambient has compared the Narwal Flow 2 and Dreame Matrix10 Ultra, two flagship robot vacuums that advertise around 30,000Pa of suction but take different approaches to mopping and automation. Its findings are unevenly sourced: The Ambient tested the Narwal in its lab, while its account of the Dreame draws on specifications and a review by sister site Trusted Reviews, so a direct comparison remains incomplete.
The Narwal Flow 2 uses a heated, track-style roller mop that is supplied with water at 60°C and applies 12N of pressure. The Ambient says its tests removed dried coffee and red-wine stains in one pass and mud in two; dried ketchup required pretreatment with kitchen cleaner. The robot’s dock washes the mop with water at 100°C.
The Matrix10 Ultra instead uses two detachable spinning pads. Its dock also washes pads at 100°C, and can automatically select among three pad types intended for different rooms: thermal for living areas, nylon for kitchens and sponge for bathrooms and spills. The Ambient describes this setup as more flexible, but says it has not yet tested how the pads perform against the Flow 2’s roller.
The quoted suction figures are 31,000Pa for Narwal and 30,000Pa for Dreame. The Ambient’s Flow 2 testing found it cleared flour from carpet in two passes and dust from hard floors in one vacuum-only run. These results are not a head-to-head comparison: equivalent lab results for the Matrix10 Ultra were not supplied.
Mopping Choices Shape the Decision
For buyers, the comparison suggests that floor type and cleaning routine may matter more than the small difference in advertised suction. Narwal’s system has demonstrated stain-cleaning results in The Ambient’s lab, while Dreame’s automatic pad swapping is designed to adapt the mop to different rooms without requiring the user to change pads manually.
Carpet clearance is another practical distinction. The Flow 2 lifts its roller by 10mm; The Ambient says that may be adequate for short-pile rugs but might not keep the mop clear of deeper carpet. The Matrix10 Ultra lifts its pads by 10.5mm and, according to the comparison, detaches them on long-pile carpet. That feature could make the Dreame a better fit for homes with thick rugs, although independent testing of its performance is still needed.
Prices also differ by market and currency. Dreame’s UK store listed the Matrix10 Ultra at £999, discounted to £799 when The Ambient reported it. Narwal’s US store listed the Flow 2 at $1,299.99, reduced from $1,499.99, and its European price was €1,299. Narwal had not confirmed a UK price, so the available figures do not establish a like-for-like local comparison.

Two Different Dock Strategies
Both machines pair their robots with docks that empty dust, wash mops in 100°C water, dry them with hot air and dispense detergent. Their approaches diverge in capacity and maintenance. Narwal’s dock has a 2.5-litre dust bag rated by the company for up to 120 days, alongside 4.5-litre clean-water and 4-litre dirty-water tanks. Narwal says users can use their own floor cleaner rather than proprietary cartridges.
Dreame’s dock has a 3.2-litre dust bag rated for up to 100 days and automatically refills a compartment holding three cleaning solutions. The quoted hands-free periods are manufacturers’ estimates, not independent measurements of how long a particular household can go between maintenance. The Ambient also reports that the Flow 2 is 95mm tall, while the Dreame can lower to 89mm when its laser sensor retracts.
The comparison includes navigation and obstacle-avoidance claims, but the evidence differs by model. The Ambient says the Flow 2 avoided shoes, cables and simulated pet mess in its tests. Dreame says the Matrix10 Ultra can recognize more than 240 object types; that is a manufacturer claim in the source, rather than a result from The Ambient’s own testing.
“The more useful difference between them is how they mop, how well they can navigate, and how easy they are to use.”

The Missing Head-to-Head Test
The biggest limitation is that The Ambient has not reviewed the Matrix10 Ultra. Its account uses the manufacturer’s specifications and Trusted Reviews’ assessment, while its detailed stain, carpet and obstacle results apply to the Narwal. The comparison therefore does not establish which robot cleans better under identical conditions.
Some specifications are also unavailable in the source. Dreame does not disclose a battery capacity or runtime there, and its mop pressure is not stated. Narwal’s claim of noise below 56.5dB and its battery rating of up to 190 minutes are company-provided figures. Results may also depend on settings, floor surfaces and home layouts.
UK pricing for the Flow 2 had not been confirmed at publication, and promotional prices can change. The comparison also does not provide enough information to determine the total long-term cost of replacement bags, cleaning solutions or mop components for both models.
A Dreame Lab Review Is Pending
The Ambient says it plans to update the comparison after testing the Matrix10 Ultra. That review should provide a more direct basis for comparing stain removal, carpet pickup, obstacle avoidance and the practical performance of the two mop systems.
Until then, buyers can compare the stated features against their own homes: the Flow 2 has lab-tested roller-mop results and a published battery rating, while the Dreame offers automatic pad changes, pad detachment for long-pile carpet and a lower profile when its sensor retracts. Shoppers should check current local prices and treat manufacturer performance and maintenance estimates as claims rather than guaranteed outcomes.
Key Questions
Which robot vacuum has been tested by The Ambient?
The Ambient tested the Narwal Flow 2 in its Home Technology Lab. It had not yet reviewed the Dreame Matrix10 Ultra when it published the comparison.
Which model has the higher advertised suction?
The Narwal Flow 2 is listed at 31,000Pa, compared with 30,000Pa for the Dreame Matrix10 Ultra. Those figures are specifications, and the comparison does not provide equivalent lab results for both models.
Which one may suit a home with thick rugs?
The comparison says the Matrix10 Ultra detaches its mop pads on long-pile carpet. The Flow 2 lifts its roller by 10mm, which The Ambient says may be less suitable for deeper carpet. A direct test of the Dreame’s carpet performance is still pending.
How do their mopping systems differ?
The Flow 2 uses a heated track-style roller that is cleaned as it works. The Matrix10 Ultra uses two spinning pads, and its dock automatically swaps among three pad types intended for different rooms.
Are their prices directly comparable?
Not from the figures in the report. It lists UK pricing for the Dreame and US and European pricing for the Narwal, but says Narwal had not confirmed a UK price. Prices and discounts may also change.
