Verdict
Pick the Roomba s9+ if Tom’s Guide-style dry debris and pet-hair pickup is the only job and you do not need mopping. Pick the Curv 2 Flow if you want a current mop-and-vac dock system — The Verge highlights its roller mop — and you accept a lower pet-hair score on that Tom’s Guide table.
Overview
These robots are from different generations. The Roomba s9+ is a high-suction iRobot vacuum with a Clean Base. The Qrevo Curv 2 Flow is a 2025/2026 Roborock with a roller mop and a maintenance dock.
Pickup scores
Tom’s Guide lists the s9+ at 96.82 overall, 92.5 cereal, 100 kitty litter, and 98 pet hair. The Curv 2 Flow is 89.5, 96.25, 97.5, and 75. Cereal is the one debris type where the Curv leads on that table.
Mopping
The Verge recommends the Curv 2 Flow specifically for mopping (SpiraFlow roller, about 15 N downward pressure, 20,000 Pa). The s9+ does not replace a mop.
