How we reached each verdictThe numbers behind each model's score
Roborock Qrevo Curv 2 Flow
All 5 expert reviewers tested it hands-on, and 3 of 5 call it best suited to homes with mostly hard floors. Mopping is the headline: Wired, Tom's Guide and ZDNet rate it strongly, while Vacuum Wars found dried stains among the weakest it has measured, and RTINGS saw no improvement over the original Curv. Owners are broadly positive, with 45% of 215 first-hand owners praising suction and 39% praising mopping, and only 6% mentioning failures. Evidence on long-term durability and parts costs is thin, and pet-hair performance on carpet is genuinely contested.
Roborock S8 MaxV Ultra
The evidence here is deep: 7 hands-on expert reviews and 456 owner comments, 411 of them first-hand. Experts score it 81 and owners 73, with 4 of 7 reviewers calling it their best or top-tier robot cleaner, and 38% of owners praising its suction versus 5% complaining. Mopping is more divisive among experts (5 of 7 note streaks, stubborn stains or only okay results), though owners lean positive at 27% praise versus 8% complaints. The main caution is durability and value: reliability scores 64, 15% of owner comments mention failures, 9% say it broke or died, and 7% cite poor customer support.
