How we reached each verdictThe numbers behind each model's score
Eufy Omni C20
Evidence is moderately thin: 4 expert sources, only 3 of which tested it hands-on and just 2 of which publish scores, while Consumer Reports' page offered no verdict. Owners are warmer (score 75) than experts (63), with 31% of 109 owner comments praising value and 21% each praising suction and mopping. The recurring weak spots are navigation (12% of owners complain, and all 3 hands-on reviewers flag poor obstacle avoidance), hair tangles (9%), and getting stuck (6%), with failures mentioned in 10% of comments. Amazon shoppers give it 3.9 stars across 173 ratings, and it typically sells for well under its $700 list price.
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.
