Source: hobot.com.tw (verified 2026-08-01). Fetched live from HOBOT's Taiwan site: embedded UPS holds position 20 minutes on power loss, 4.5m/200kg safety rope, ~4min/m^2 cleaning speed, ultrasonic spray, AI auto edge-detect, 4m power cord, 3 auto modes. Suction figure and noise (dB) are not stated in the extractable text of that page (shown only as an image graphic) and were left null rather than reusing a different HOBOT model's number. Weight (915g/32.27oz) and dimensions (295x148x95mm / 11.6x5.8x3.7in) are from a manufacturer-authored blog post on hobot.us (via search-engine cache; direct hobot.us fetch blocked, HTTP 429) and a 2020 Gadgetgram launch article (fetch blocked, HTTP 403), both consistent with each other. Release year 2020 per that Gadgetgram article date.
