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 rate the Saros 20 as a top-tier performer, with its suction, low profile and threshold climbing praised across the board. ZDNet found it the best of the robots it tested on medium-pile carpet. Owners are warmer about cleaning (31% praise suction, 18% praise mopping) than about getting around: 14% praise navigation, while 10% criticize it and 5% say it gets stuck. That gap helps explain an owner score of 62 against an expert score of 84. Every reviewer flags the price, and two call it only an incremental step over the Saros 10 and 10R. Reliability evidence is reassuring, with failures mentioned by just 5% of owners, but long-term durability data is still limited because the model is new.
