A practical comparison
Qrevo Edge 3 Pro, Edge 2 or Curv 2 Flow?
Roborock's Qrevo Edge 3 Pro, Qrevo Edge 2 and Qrevo Curv 2 Flow are not simply successive levels of one robot. The exact Edge 3 Pro US page said it had not launched yet when checked on October 23, 2026, so treat its details here as a model reference rather than a ready-to-buy choice. The useful split is between two spinning-pad designs and a powered roller, followed by what each exact dock and manual actually say. Check the route and maintenance plan first; a product name or headline temperature cannot answer those questions by itself.
Edge 3 Pro: the newer spinning-pad package
The Edge 3 Pro pairs a 3.14-inch, retractable-LiDAR robot with two rotating pads. Roborock describes warm-water mopping, but its exact US FAQ does not give a numeric temperature for water on the floor. Separately, the station is rated for mop washing up to 100°C and drying with 55°C air. It also auto-empties dust, refills from removable clean and dirty tanks, dispenses cleaner and self-cleans. This is a broad set of automated chores, not a plumbing installation or a maintenance-free dock.
Its 36,000 Pa maximum suction and over-300 obstacle-type statements are manufacturer claims, not independent pickup or avoidance results. The Edge 3 Pro does publish a 1.77-inch single-level threshold maximum and a qualified 3.46-inch double-layer maximum. The larger figure has geometry conditions: the first rise must be no more than 1.77 inches, the gap must be greater than 4.72 and no more than 5.51 inches, and the second rise no more than 1.69 inches. Do not treat that as a 3.46-inch single-step promise. Its exact manual also requires 2.4 GHz Wi-Fi and cold tap water in the clean-water tank; it says to keep the floor free of water and sticky substances. Roborock claims dynamic carpet cleaning up to 1.18 inches with the feature manually enabled in the app; the claim does not establish thicker carpet or independent performance.
Edge 2: an explicit floor-water temperature
Edge 2 keeps the low retractable-LiDAR format and dual spinning pads, but the exact US FAQ gives a more specific mop-cycle figure: warm water up to 60°C. Its station washes pads up to 80°C and dries at up to 55°C. That makes it easier to answer a buyer who specifically wants a stated floor-mop-water temperature. It does not make the model universally better at stains; these are maker specifications, not side-by-side cleaning results.
The exact Edge 2 package is a tank dock too. It lists 25,000 Pa maximum suction and over 280 object categories, and its product sources do not give a numeric threshold-crossing maximum. Its FCC manual explicitly says not to use it on high-pile carpet and cautions about reduced effectiveness on dark carpet. That direct caution is more decisive than an automatic mop-lift feature if the household's carpet is a deal-breaker. Like Edge 3 Pro, it is 2.4 GHz-only and not for wet or sticky-floor pickup.
Curv 2 Flow: change the mop mechanism
Curv 2 Flow's defining difference is its powered, refreshed roller rather than two separate rotating pads. It is also noticeably taller in the reviewed US configuration: Roborock lists about 4.69 inches. Its dock is a removable-tank multifunction station, and the reviewed materials identify roller cleaning, dock wash and drying behavior rather than a plumbed water line. Its maximum suction and dock claims belong to that exact package, not to the similarly named Edge series.
A roller may be the right choice if you specifically want a roller that is continuously supplied and scraped as it works; it will not be interchangeable with an app setting on a twin-pad model. The body height can rule it out under low furniture even when its floor mechanism appeals. The exact manual cautions against high-pile carpet and liquid or sticky substances, and requires 2.4 GHz Wi-Fi. The dock still asks for tank, tray, roller and consumable care.
Choose by the question you can actually answer
If an exact published temperature for water used on the floor is essential, Edge 2 has the clearest figure among these three; Edge 3 Pro's 100°C is a dock-wash figure, while its floor-mop warmth is not numerically specified. If the priority is the newest listed 100°C pad-wash dock and a low retractable sensor, Edge 3 Pro is the better specification match, provided the double-step claim and unknown carpet status work for your home. If a continuously refreshed roller is your requirement, compare the Curv 2 Flow's taller body and roller-care routine against the two pad designs.
Before choosing any of them, measure the narrowest opening and the actual transition, then reserve the dock's manual-specified clearance. Confirm the network band, check whether your carpet is permitted by the exact model manual, and decide who will fill and empty the tanks, clean the wash tray and replace bags or cleaner. Neither mop mechanism should be used to collect a puddle: each reviewed manual restricts running over water or sticky material. These are different ways to automate routine floor care, not substitutes for preparing a safe route. Read Roborock’s exact Edge 3 Pro feature details and the full Edge 3 Pro, Edge 2 and Curv 2 Flow assessments, then verify the floor plan against the exact Edge 3 Pro product information and its manual.
