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 Z70
Across 12 hands-on expert reviews, the verdict is remarkably consistent: an excellent vacuum and mop held back by its OmniGrip arm, which 11 of 12 call unreliable or limited. Consumer Reports offers only a preliminary look with no test results. At least 6 reviewers point buyers toward cheaper armless models such as the Saros 10R. Among 469 owner comments, 31% praise its cleaning, 18% its mopping and 17% its navigation. Complaints are fewer: 8% call it poor value, 5% cite customer support and 4% report breakdowns. Retail ratings are split, with 3.1 stars on Amazon (176 votes) but 4.33 at Roborock's own store (341). Long-term durability evidence is thin, and one reviewer notes major replacement parts reportedly won't be offered.
