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 Saros 20
All 6 hands-on expert reviews agree the Saros 20 is a top-tier cleaner, with standout suction, threshold climbing and a slim profile, and the expert score of 84 reflects that. Owners are cooler at 62: the most common praise is suction (32% of 496 comments) and mopping (18%), but 9% complain about navigation, 6% about value, and 5% about it getting stuck. Reliability looks solid, with failure mentions in only 6% of comments and no recalls, though long-term durability data is thin for a newer model. Amazon shows 4.2 stars from about 4,500 votes, and Roborock's own store shows 4.51 from 376.
