Qrevo Edge 3 Pro vs Saros 20 Flow: Same Pascal Number, Different Mop
Roborock did not bring one flagship to IFA 2026. It brought a naming problem.
On September 3, Vacuum Wars unpacked the Berlin lineup. The machine announced abroad as the Saros 20 Neo is coming to the United States as the Roborock Qrevo Edge 3 Pro. Same 36,000 Pa claim, dual anti-tangle brush, AdaptiLift Chassis 3.0 rated for double-layer thresholds at 8.8 cm, about 3.5 inches, plus a multifunctional dock. The other machine, the Saros 20 Flow Complete, keeps the Saros name, keeps the same 36,000 Pa, and bets the article on a self-cleaning roller mop. Android Headlines gave the Flow an IFA award. Vacuum Wars called it the more technically interesting robot over the longer term, then refused to score either one until the studio tests land.
We already ran Saros 10R against Dreame X50 Ultra. That was last year’s ceiling. This is two 2026 Roborocks that share a suction number and disagree about water.
Specs that are actually in the write-ups
| Qrevo Edge 3 Pro (Saros 20 Neo) | Saros 20 Flow Complete | |
|---|---|---|
| Official suction | 36,000 Pa | 36,000 Pa |
| US nameplate | Yes, Qrevo Edge 3 Pro | Still Saros in the IFA coverage |
| Chassis | AdaptiLift 3.0, 8.8 cm / 3.5 in thresholds | Not the headline |
| Hair | Dual anti-tangle | Dual lifting arc side brushes |
| Mop | Not the lede in VW | SpiraFlow 2.0 roller, 15 N, 240 r/min, 16 water outlets |
| Nav / avoid | Low-profile body | RetractSense LiDAR; Reactive AI, 300+ object types |
| Dock | Multifunctional | Fully automated base, high-temp mop wash |
| Independent test | None yet | None yet |
| Street price | Not published in these pieces | Not published in these pieces |
36,000 Pa next to 36,000 Pa is a brochure tie. Pascal ratings have been the industry’s favorite unfalsifiable number for three years. Believe the chassis and the mop. Do not believe the tie.
What the Edge 3 Pro is for
Vacuum Wars’ US note is the whole plot. If you are shopping in America this fall, the Neo is not a Saros on the box. It is a Qrevo. That will confuse anyone who followed last year’s Saros 10 / 10R naming, and it will help anyone whose retailer search bar still autocompletes Qrevo.
The 8.8 cm threshold rating is the number I would actually pay for. Door bars, chunky transitions, the dumb wood strip between kitchen tile and living-room oak: last year’s AdaptiLift talk was 40 mm on the 10R, and even that needed the threshold mapped in the app. 88 mm is a different class of house. If your floor plan has a sunken living room or a 1950s sill, this is the robot in the table.
Dual anti-tangle is Roborock speaking to people with dogs. Every dock-vac launch says this. The only evidence in the IFA notes is the claim. Wait for Vacuum Wars to wrap hair around the roller on purpose.
Low-profile is the other practical spec. IFA was full of robots that duck under sofas. CNET watched Dreame’s X60 Ultra Complete Pro do the obstacle course at a speed they do not usually associate with robot vacs, then heard a Dreame rep say there are no confirmed US plans, with FCC-ban and waiver noise on top. An impressive demo that cannot ship is not a competitor you can order. The Edge 3 Pro is the one with a US name.
What the Flow is for
Android Headlines cared about water. SpiraFlow 2.0 is a roller mop, not spinning pads. 15 newtons of downforce, 240 revolutions per minute, 16 pressurized outlets. The dock washes the roller hot. Vacuum Wars groups that with a broader shift: self-cleaning rollers with continuous water and real pressure, instead of a damp pad that paints juice around the kitchen.
If you mop more than you vacuum, the Flow is the interesting machine. If you have light carpet and a lot of grit, a roller that stays wet is also how you soak a rug. Roborock will claim carpet detection. Every brand does. The studio test is whether it lifts in time.
RetractSense LiDAR plus Reactive AI on 300-plus object classes is the other half of the award. Cords, shoes, toys. We have heard 100 objects, then 200, then 300. The useful question is still whether it eats the one charging cable you forgot. Android Headlines says low light is fine. Believe that after a night run, not a booth.
The Flow’s US timing is the gap. VW is clear about the Neo’s American name. It is not as clear that the Flow Complete is on the same boat. An IFA award does not place an order with a US warehouse.
The rest of the booth, so you do not buy the wrong robot
Roborock also showed the F25 Ultra Steam Gen 2, a wet-dry stick with high-temp steam and a short claimed warm-up, headed to the US. The F25 Pro Turbo Combo swaps between stick vacuum and wet-dry mop, 25,000 Pa, SlideTech 2.0 wheels, JawScrapers brush. No US availability in the VW piece. Pool cleaner and a wire-free lawn mower: also no US date.
CNET’s IFA trend piece is the context for allergen claims. Eufy’s Omni E35 and Ecovacs’ Deebot X12S Omnicyclone both showed up with certifications. The X12S, tested by SGS in Singapore, removed an average 97.44% of dust mite allergens and 95.45% of dust mites from carpet in that test. If asthma is the reason you are in this aisle, a certified allergen run may beat another 1,000 Pa on a Roborock banner. That is a different comparison than the one in this table.
Dyson brought 11 new products, including robot vacs, off-site. CNET’s David Watsky noted the pace. Pace is not a pickup score.
What IFA still does not tell you
Battery minutes. Dustbin size. Whether the dock needs a drain or just a tank. Noise at 2 a.m. How long the mop takes to dry so it does not smell like a gym bag in week three. Vacuum Wars flagged all of that by refusing to rank on a press wall.
Obstacle counts are the other unearned number. 300 classes sounds like a brain. It is a training set. The cable that kills runs is always the one that looks like the floor.
If you have mixed floors, the Flow’s wet roller is the risk. If you have one long rug in a hard-floor apartment, watch a review that shows the lift, not a booth clip of a robot circling a shoe.
Thresholds cut the other way. 8.8 cm is a gift in an old house and irrelevant in a new build with 5 mm transitions. Measure the tallest bar with a ruler. Do not buy chassis travel you cannot use.
Miele’s HX3 stick lineup at IFA, which CNET handled in a separate piece, starts at $849 and runs to $1,249 with the Aqua mop head. That is a human-held vacuum. It is the honest alternative if you wanted pickup more than autonomy. A robot that cannot climb the sill you actually have is a $1,000 mop with a map.
Who should buy which
Buy the Qrevo Edge 3 Pro if you are in the US, you have real thresholds, and you want the machine that already has a domestic nameplate. You are trading away the roller-mop science project for a robot you can actually hunt at a retailer.
Buy the Saros 20 Flow Complete if mopping is the job, you can wait for US stock to be confirmed, and you like the idea of 15 N on a roller that the dock cooks. You are an early adopter with a hard-floor house.
Buy neither until Vacuum Wars publishes the studio numbers if you already own a Saros 10R that does not infuriate you. Last year’s S8 MaxV Ultra vs Roomba Combo j9 argument still applies: the dock you have is worth more than a Pascal number from a press wall.
Winner, for a US kitchen this fall: Qrevo Edge 3 Pro. Not because 36,000 is bigger. It isn’t. Because 3.5-inch thresholds and a name you can order beat an award-winning roller that still has to clear customs.
Prices were not in these articles. If a preorder lands $400 apart, that gap is larger than the mop philosophy. Wait for the tag, then wait for a hair wrap test.
If you are replacing a dead Roomba, do not wait for both IFA machines. The Edge 3 Pro is the one Vacuum Wars already mapped onto a US SKU. The Flow can be the upgrade next spring if the roller tests hold and the dock does not need a plumber. Two robots from one booth is a gift for a comparison table. It is a bad reason to own both.
