robotindex ECOVACS WINBOT W2 PRO Omni
A suction-mounted window-cleaning robot with a safety tether and edge-detection sensors for frameless glass. The Pro tier's cord-connected station is a portable power pack that lets it charge while actively cleaning, rather than a water-refill dock.

Reference Price
Ecovacs.com and Amazon list $499.99, while TechRadar cites a $699.99 ($699.99 / AU$999) MSRP — robotindex could not resolve whether this reflects a standing promotional price or a regional/timing difference, so both figures are shown pending clarification.
Sensors & Hardware
The W2 Pro Omni attaches with up to 5,500 Pa suction and a tether rated to ~100kg via carabiner backup. Edge detection uses optocoupler/spherical sensors (claimed 0.2s response) plus bumpers for framed windows. Unlike Deebot "Omni" vacuum stations, this Winbot's dock isn't a water-refill/pad-washing station — it's a portable power pack that lets the Pro charge continuously while cleaning.
Insights
Price for the W2 Pro Omni is reported inconsistently across sources: Ecovacs' own store and Amazon list $499.99, while TechRadar cites a $699.99 MSRP. It's unclear whether this reflects a standing promotional price or a regional/timing difference. Ecovacs has since introduced the newer W2S OMNI and W3 OMNI models, which now lead the window-robot line — the W2 Pro Omni covered here is a step behind Ecovacs' current flagship window cleaners.
Firmware & Community
Closed platform
ECOVACS WINBOT W2 PRO Omni has not released a public SDK, firmware repo, or developer API. Not currently listed in Builds & Mods.
Specs sourced from Ecovacs' own US product page (ecovacs.com/us/shop/winbot-window-cleaning-robot/winbot-w2-pro-omni), TechRadar's review, and Tom's Guide's coverage, as of September 2026. Price is reported inconsistently ($499.99 vs. $699.99) across the sources checked — both are shown rather than picking one arbitrarily. The W2S OMNI and W3 OMNI successor models are confirmed via 9to5Google and Ecovacs' own current product pages. No formal safety certification (e.g., UL) was found referenced for this model. Moved from Featured to Under Review because it's no longer Ecovacs' top window-cleaning model — the W2S OMNI and W3 OMNI have taken that position. robotindex does not sell this product.
