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.

Amazon shoppers give it 3.9 stars across 173 ratings, and it typically sells for well under its $700 list price.
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.
