Roborock Qrevo Curv 2 Flow Review 2026: Specs, Roller Mop and Verdict
Roborock's roller mop Qrevo: what changed from the original Qrevo Curv, where it beats the flagships and where it falls short.
By , research by the BestBots team · Updated Oct 18, 2026
Fact checked against each company's published pricing, documentation and verified user ratings. How we score
The Roborock Qrevo Curv 2 Flow is the best value roller mop robot in this guide: 20,000 Pa suction, a SpiraFlow roller that rinses itself as it mops, a 15 mm carpet lift and 200+ obstacle types. It gives up flagship suction and low clearance, since it stands 4.7 inches tall. Buy it for hard floors that get mopped every day.
The Curv 2 Flow is the value pick of the Roborock lineup: a self cleaning roller mop with 2.5 times the mopping pressure of the original Qrevo Curv, a 65 day dust bag and 200+ obstacle types. It gives up the Saros models' suction and thresholds, and Matter is still pending an update.

What it is
The Qrevo Curv 2 Flow is the roller mop successor in Roborock's Qrevo Curv line. The original Qrevo Curv, with dual spinning mops and 18,500 Pa, no longer appears in Roborock's robot vacuum collection as of October 2026; the Curv 2 Flow and the Qrevo CurvX do. The Curv 2 Flow keeps the rounded Curv dock and adds a roller.
The core spec sheet: 20,000 Pa HyperForce suction, a SpiraFlow roller mop with real time self cleaning, 2.5 times the mopping pressure of the Qrevo Curv (which ran up to 6 N), a roller that lifts up to 15 mm on carpet, structured light and RGB camera obstacle avoidance that recognizes 200+ object types, and a 5,200 mAh battery. The robot measures 13.9 by 13.9 by 4.7 inches.
The dock washes the roller with 167°F (75°C) water, dries it with 131°F (55°C) air, empties dust for up to 65 days and uses dirt detection to trigger a rewash.
Pricing explained
The Qrevo Curv 2 Flow is sold on Amazon and on Roborock's store, so we do not list a price. Check the current price at either retailer.
Running costs to plan for:
- Dust bags. About 65 days per bag, so roughly five to six a year.
- Roller mop. Rollers wear like pads do. Third party kits on Amazon bundle rollers, brushes, bags and filters for this model, which tells you the replacement cadence is real.
- Cleaning solution. Optional, but the dock is designed around it.
- Water hookup. Roborock lists an optional refill and drainage variant for the Curv family. It saves refilling tanks but needs a water line near the dock.
Where it sits: below the Saros 20 and Saros Z70 in Roborock's lineup, above the Q series entry robots like the Q7 M5+.
Key features
SpiraFlow roller mop
A roller mop stays in contact across its whole width and is rinsed and scraped during the run, so it is not pushing dirty water around between dock visits. That is the main reason to choose this model over a spinning pad Qrevo. Roborock says the pressure is 2.5 times the original Curv's 6 N.
Carpet handling
The roller lifts up to 15 mm when the robot detects carpet, and the robot applies adaptive strategies such as more suction. Spinning pad robots like the Saros Z70 can remove their mops entirely; the Curv 2 Flow keeps the roller on board and lifts it.
Suction and anti tangle
20,000 Pa with Roborock's dual anti tangle system. That is enough for hard floors and low pile rugs. Thick carpet and heavy shedding favor the 31,000 to 36,000 Pa flagships.
Obstacle avoidance
Structured light and an RGB camera recognize 200+ object types, up from 62 object types on the original Qrevo Curv. That covers cords, shoes, pet waste and toys.
Dock
167°F mop wash, 131°F drying, about 65 days of dust, dirt detection rewash. It is not as hot as the 212°F docks on the Saros 20, Dreame X60 Max Ultra Complete and Narwal Flow 2, but it is hotter than eufy's 140°F.
App and voice
The Roborock app with SmartPlan 3.0 tailors suction and rewash by room. Real time video calls, pet tracking, Alexa, Siri and Google Home are supported, and an offline voice assistant answers commands. Matter is promised by update. Roborock supports up to four floors of maps.
Noise
62 to 65 dB in vacuum and mop mode, per Roborock.

What users say
The Amazon listing for the Qrevo Curv 2 Flow shows 4.2 out of 5 from 1,399 ratings as of October 2026, level with the Saros 20 and ahead of the Saros Z70's 4.0. For a model launched in 2026, that is a solid early base. Amazon ratings are listing level and can include more than one color.
Privacy and security
The robot has an RGB camera for obstacle recognition and supports video calls and pet finding through the app. Roborock's Saros 20 page says Roborock follows global data privacy standards, and its site lists a vulnerability disclosure policy and a software security support policy. Keep video features off if you do not use them.
Who it is for
- Hard floor homes that mop daily and want a roller instead of pads
- Pet homes on a mid range budget
- Owners of an older Qrevo or S series who want real time mop rinsing
- People who want Roborock's app without paying for a Saros
Who should skip it
- Homes with low sofas and beds: at 4.7 inches it is the tallest robot here except the eufy C28
- Thick carpet and heavy shedding: look at the Saros 20 or Dreame X60 Max Ultra Complete
- Matter households that need it today
Alternatives
- Narwal Flow 2: a heated track mop, 31,000 Pa and a 120 day bag
- eufy Omni E35: 35,000 Pa roller mop and up to 180 minutes runtime
- iRobot Roomba Max 875 Combo: roller mop with a carpet sealing skirt; see our head to head
- Dreame X60 Max Ultra Complete: thinner and more powerful; see Dreame vs Roborock
- Ecovacs Deebot X12S OmniCyclone: roller mop with a bagless station
Verdict
The Qrevo Curv 2 Flow puts a self cleaning roller, 200+ object recognition and Roborock's app into the mid range. It is the robot most people who mainly have hard floors should look at first. Step up to a Saros or a Dreame X60 if you have thick carpet or low furniture.

What is the difference between the Qrevo Curv and the Qrevo Curv 2 Flow?
The original Qrevo Curv uses dual spinning mops, 18,500 Pa suction and recognizes 62 object types. The Curv 2 Flow switches to a SpiraFlow roller mop with real time self cleaning, raises suction to 20,000 Pa, raises mopping pressure 2.5 times and recognizes 200+ object types, per Roborock.
Is the Qrevo Curv 2 Flow a roller mop?
Yes. The Flow in the name refers to the SpiraFlow roller mop, which is rinsed and scraped continuously while the robot cleans, so it does not have to return to the dock as often to wash pads.
Does the Qrevo Curv 2 Flow work with Matter?
Roborock says Matter will be available through an upcoming over the air update. Alexa, Siri and Google Home work now.
How long does the Qrevo Curv 2 Flow take to charge?
Roborock's FAQ says the 5,200 mAh battery takes about 3 hours to charge from 15% to full. Roborock does not publish a runtime in minutes for this model.
Is the Qrevo Curv 2 Flow good for pet hair?
It has Roborock's dual anti tangle system, 20,000 Pa suction and 200+ object recognition, which covers pet waste. For heavy shedding on thick carpet, the 36,000 Pa Saros 20 or 35,000 Pa Dreame X60 Max Ultra Complete have more suction.
How loud is the Qrevo Curv 2 Flow?
Roborock lists 62 to 65 dB in vacuum and mop mode, which it compares to a refrigerator hum.
Where can I buy the Qrevo Curv 2 Flow?
Roborock sells it on Amazon and on its own store. We do not list robot prices; check the current price at either.
