How we reached each verdictThe numbers behind each model's score
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.
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.
