The most interesting cases where individual AIs diverged from the consensus ranking
We asked 15 leading AI models the same question and combined their independent rankings using weighted scoring. Each robot vacuum earns points based on its position in each AI's list, with bonuses for consensus agreement and top-pick placement.
Total Score = Position Points + Top Pick Bonus + Consensus Bonus
No single AI's bias. No paid placements. Just the robot vacuums that multiple AIs independently agree are the best.
AI Agreement measures how strongly the top-ranked robot vacuum dominated across all 15 AI models. A higher percentage means more AIs independently ranked it near the top.
Agreement = (Appearance Count × Avg Position Score) ÷ Maximum Possible Score × 100
Moderate consensus — most AIs agree but there is some variance in rankings.
"Slop" is the noise in AI-generated data — duplicates, hallucinated entries, naming inconsistencies, and one-off picks that only a single AI mentioned. The Slop Score measures how much cleaning we had to do to produce a reliable ranking.
Moderate slop — some duplicates and inconsistencies were found and resolved. The final ranking is solid.
We sort through the slop so you don't have to.
