Safety

Holds on without power: Over 30 min, the maker says; Maker says, Oct 30, 2026
Safety guidance: Product page: "Even if the power level is low, the WINBOT will remain attached to the window for over 30 minutes." "The safety rope is made from a three-layer, compound cable with a strong tensile strength of up to 100KG. The station is also equipped with a 1m safety rope at the bottom of the station for added protection."
Category FAQ: "WINBOT robotic window cleaner can work on tinted or colored glass as long as the surface is smooth and free of decals or stickers, cracks, obstacles under 4 mm, or frames under 2 mm. The window should also not be too small, curved, or irregularly shaped, and it must be free of condensation or oil stains. Do not use the robot in extremely cold or hot conditions."; Maker says, Oct 30, 2026
Nothing else found: No FCC ID, UL or ETL found in the certifiers’ databases or on the maker’s page. CSA’s listing not searched yet.Maker’s page: Read on the maker’s US product page. The manual it links is the 220-240 V version (“Model WG893-12”); a W2S OMNI Americas manual linked from the W2S PRO OMNI page says “Model WE005V01”.
FCC ID: The FCC has a record for 2A64B-WG893 (window cleaning robot, May 20, 2025), but the only manual on this robot’s US page is the 220-240 V version, and ECOVACS’ Americas manual names a different model (WE005V01). The US model isn’t clear, so I don’t count it.
Searched the FCC’s database: Ecovacs Home Service Robotics (2A64B): WG893, WE005V01.
UL: UL Product iQ lists Ecovacs Robotics for power units and battery charging systems, not for a robot model.
Searched UL Product iQ for “Ecovacs”, “WG893”.
ETL: Intertek’s Directory of Building Products needs a bot check to run a search, so I read its list of 3,061 listed companies instead. Ecovacs isn’t on it.
CSA: The maker doesn’t state one. CSA’s listing isn’t searched yet: it opens on directories.csa-international.org, which my browser couldn’t load on Nov 2, 2026.; Checked Nov 2, 2026
Recalls: No recall found on cpsc.gov, checked Nov 2, 2026Searched cpsc.gov recalls for “Ecovacs”, “WINBOT”, “robotic”, “robot”.
