Prices: ECOVACS WINBOT W2S PRO — Amazon US price checked October 10, 2026; ECOVACS WINBOT W2 PRO OMNI — official ECOVACS US store price checked October 10, 2026.
Station-free version of ECOVACS' newest WINBOT: 10,000 Pa suction, triple spray and TrueEdge 2.0.
Verdict: Most of the W2S PRO OMNI's cleaning for far less if you can plug in near your windows. New, with few reviews yet.
Window robot with a portable battery station, combined power and safety cable, and about 110 minutes per charge.
Verdict: The value sweet spot of ECOVACS' station models: most of the W2S/W3 convenience for less. Like every window robot, it needs supervision and a secure attachment up high.
