5 models evaluated · best Verdict Score 73/100 · Updated September 15, 2026
Ecovacs is the only maker with a whole window-robot range in our catalogue, and the models differ mostly in suction and in how they are powered. The WINBOT W2S OMNI and the W2S PRO OMNI run from a station with its own battery, so the 5.5 m cable is to the station rather than a socket: 8,000 and 10,000 Pa of suction, an 80 and a 120 ml tank for about 50 and 75 m² per fill, corner cleaning and 110 minutes of runtime. The W2 PRO OMNI is the earlier OMNI at 5,500 Pa, and the W2 PRO the same robot on a plain 5.5 m cable at 5,300 Pa, both cleaning about 40 m² per 60 ml fill. The WINBOT MINI is the small one: 7,500 Pa, a 3.5 m cable, 25 m² per fill and a minimum pane of 22 by 25 cm, where the others need 30 by 40.
