Methodology: one multi-brand scan asked ChatGPT (OpenAI), Gemini (Google) and Perplexity the same real shopper prompts for robot vacuums. “Recommended” = the assistant explicitly recommends the brand; “Mentioned” = the brand appears in the answer. Scanned Jun 19, 2026. Rates are directional: brands within a few recommendations are effectively tied and their order can shift between scans, so we name a single leader only when it outscores the field more than 2-to-1.
