The short answer
- Buy the Roomba Max 875 if you have a lot of carpet, already use the Roomba app, and want the longest dock interval and the most object types of these two.
- Buy the Qrevo Curv 2 Flow if your floors are mostly hard, you want a robot with a large base of owner ratings, and you would rather avoid the uncertainty of iRobot's 2025 bankruptcy.
These two replace the models most people still search for: iRobot's Combo 10 Max is now at select retailers only, and the original Qrevo Curv has left Roborock's collection.
Pricing
Both are sold on Amazon and their brands' stores. We do not list robot prices because they change often; check the current price on each listing. What differs is the cost of running them:
- Bags. The Roomba's carbon AllergenLock bag lasts up to 90 days; Roborock's lasts about 65. Over a year that is about four bags versus five to six.
- Solution. The Roomba dock auto mixes StayClean concentrate. The Roborock dock works with Roborock solution.
- Rollers and brushes. Both use rollers that wear and need replacing.

Models and features
Suction and carpet. The Roomba's 35,000 Pa and SealForce skirt are designed for carpet. Roborock's 20,000 Pa is fine for hard floors and low pile rugs.
Mopping. Both use rollers that are washed during or between passes. The Roomba heats its mist and water to 140°F on the robot. The Roborock does not heat on the robot but has 2.5 times the mopping pressure of the original Qrevo Curv and rinses the roller in real time.
Obstacles. 300+ object types on the Roomba versus 200+ on the Roborock. Both handle cords, shoes and pet waste.
Clearance. The Roomba is 0.77 inches lower, which matters under sofas.
Specific head to head scenarios
Mostly carpet with pets
Winner: Roomba Max 875. SealForce and 35,000 Pa are built for carpet, and the 90 day bag handles shedding.
Mostly hard floors, mopped daily
Winner: Qrevo Curv 2 Flow. Real time roller rinsing and a 15 mm lift do the job, and its owner rating base is large.
Low furniture
Winner: Roomba Max 875. 3.93 inches versus 4.7 inches. If you need lower still, look at the Dreame X60 Max Ultra Complete at 3.13 inches.
Long term ownership and support
Winner: Qrevo Curv 2 Flow. iRobot went through Chapter 11 in December 2025 and changed owners. Roborock has no comparable event in our sources.
Smart home on Matter
Winner: Qrevo Curv 2 Flow, narrowly. Roborock promises Matter by update for this model; iRobot does not list Matter for the 875 in our sources.
Dried on kitchen spills
Winner: Roomba Max 875. Heated 140°F mist softens dried messes before the roller scrubs.
Privacy
Both robots use cameras for obstacle recognition. iRobot says it uses high standards of data encryption. Roborock says it follows global data privacy standards and publishes a vulnerability disclosure policy. Given iRobot's change in ownership, read the current privacy policy in the Roomba Home app before setup.
Verdict
The scenarios split three and three: the Roomba Max 875 wins on carpet, clearance and dried spills, and it is the better robot for carpet. The Qrevo Curv 2 Flow is the safer buy, with a proven rating base and no ownership question. If you want Roborock with flagship specs that beat the Roomba, step up to the Saros 20.
