Method: Dataset covers 13 robot window cleaners spanning current flagship (Ecovacs WINBOT W3 Omni, W2S Omni), mainstream corded (HOBOT 2S/388/R3, Mamibot, Cop Rose, HUTT) and budget/niche (Alfawise, Gladwell, Sichler) tiers. Seed list corrections: 'Ecovacs Winbot X' (2018) is no longer listed on ecovacs.com/us/shop and has been dropped as discontinued; 'Ecovacs Winbot W2 Omni' is confirmed real but shows 'Sold out' on the current ecovacs.com US shop page, so it was replaced with its in-market successors, the WINBOT W3 Omni (CES 2026 flagship) and WINBOT W2S Omni (current mid-tier Omni model); Mamibot W120-T is a legacy (~2018) SKU no longer on mamibot.com's current lineup (which now leads with the W300/W120-DP/W120-P/W200 SkyBot) but is kept because it is still actively sold via Amazon/eBay and was an explicit seed — Mamibot W120-DP (2024, 3200Pa, 'thinnest robot window cleaner' per manufacturer) was added as the current-generation Mamibot expansion. Sichler PR-041 is a German/Austrian (PEARL/Sichler Haushaltsgeräte) private-label rebrand of HOBOT hardware (PR-041 V3 ≈ HOBOT-268 generation; the current-gen successor REF-60579 is explicitly a rebadged HOBOT-298) sold only in the DACH region — no US listing exists, so priceUsd is null by design, not by omission. suction_power_pa is left null for every HOBOT-family unit and for Mamibot W120-T, Gladwell Gecko and Cop Rose X6 where the manufacturer publishes suction only as kgf force or does not publish a figure at all (HOBOT rates 'ascending power' in kg, e.g. HOBOT-2S ≈ 6.0–7.0 kgf depending on region, HOBOT-R3 ≈ 5 kgf) — converting kgf to Pa would require assumptions about contact-cup area that were not published, so null was used rather than an estimate. battery_backup_min is the full untethered battery runtime for the dual-power Ecovacs Omni models (they can run entirely on battery) and the UPS/backup-only duration (keeps the unit clamped to the glass during a power or Wi-Fi/cable failure — NOT a cordless-use runtime) for every corded model (all HOBOT, Mamibot, Cop Rose, Alfawise, Sichler and HUTT units). Several small retailer/manufacturer storefronts (hobot.us, acevacuums.com, shop.prosperahealth.com, gladwellclean.com, robowindow.com — all Shopify-hosted) returned HTTP 429 bot-protection responses on every direct fetch attempt during verification, and Amazon.com product pages could not be rendered at all (consistent 500 errors); where this blocked confirmation of a live US price, priceUsd was left null with the conflicting/partial figures actually found (search-engine cache snippets of the real page, other regions, or older press coverage) documented in priceNote/provenance rather than guessed. Every image was independently fetched and visually confirmed to show the correct product (read back as a decoded image) before inclusion, except where noted 'omitted' in provenance because no verifiable direct image file could be found. accessedAt 2026-08-01 for all sources, corroborations and images unless individually noted.
