Evergreen monthly benchmark — May 20
Robot Vacuums
May 20Rank Trend
How top brands moved week over week. Rank 1 is the top position.
For a busy pet-owning family with a mixed-floor home, AI overwhelmingly routes to Roborock first And Dreame second, with the entire category gated behind anti-tangle brushes, self-emptying docks, and LiDAR. A brand outside the Roborock-Dreame-Eufy core is effectively invisible at the moment of purchase intent unless the buyer names it.
Top Brands by AI Mention Frequency
Mention frequency counts how many times a brand appeared across all AI responses. This differs from top-pick rank, which reflects each model’s #1 choice.
Opportunity for Brands
- IRobot is the standout opportunity narrative: high mention frequency but uniformly framed as outpaced, signaling an incumbent losing the AI-recommendation layer in real time.
- MOVA appears only in Claude and Perplexity, invisible to ChatGPT P1 and Gemini at the brand level.
- Several large brands are entirely absent: Wyze, Xiaomi, Bissell, Narwal (which appeared in the inaugural run But has since dropped from cross-model presence), Lefant, and Coredy.
- No model surfaced a clear sub-300-dollar pet-hair winner with full dock automation, leaving a budget-tier gap.

What This Means
- The four models agree on the brand hierarchy (Roborock, then Dreame, then Eufy/Ecovacs, then iRobot) but diverge sharply on specific SKUs: ChatGPT pushes the Roborock Qrevo Curv.
- Claude the S8 MaxV Ultra, Gemini the Saros 20 and Dreame X60 Max Ultra, and Perplexity the Ecovacs Deebot X8 Pro Omni.
- Claude is the most premium-leaning, recommending 1300-to-1600 dollar flagships first and making aggressive skip calls.
- Gemini uniquely elevates Eufy to flagship-tier value.
- Perplexity uniquely surfaces MOVA, TP-Link, and Eureka.
- ChatGPT is the most commerce-formatted with price-tagged carousels.
Why These Brands Win
- The brands AI favors share anti-tangle rubber brush rolls (cited as the critical pet-hair feature).
- Self-emptying docks (universal must-have for shedding households), LiDAR multi-floor mapping (table stakes for 2000-plus sq ft), and automatic mop-lift on carpet transitions.
- Premium-tier docks add hot-water mop washing and drying.
- RTINGS and Vacuum Wars are the most-cited authorities across models.

How we measure this
Each benchmark runs the same standardized prompts across multiple leading AI systems, including ChatGPT, Claude, Gemini, and Perplexity. We use consistent, category-specific questions designed to surface genuine product recommendations — not sponsored results.
Responses are parsed to extract brand mentions, rank position, and frequency. We then analyze cross-model agreement, identify which brands consistently appear in top positions, and flag where AI outputs diverge from marketplace trends.
Evergreen categories are benchmarked monthly. Results reflect organic AI behavior at the time of testing. Read the full methodology
