Overview
The W2 family pairs a square window robot with a carry-case station that holds a battery, so it can work on windows far from an outlet. The W2 Omni arrived in 2024, followed by the cheaper W2 Pro Omni and, in August 2026, the W2S Pro Omni with 10,000 Pa suction and improved corner cleaning. Reviews praise the portability and edge cleaning but note the app is basic and corners are still not fully reached on older models. The station does not wash pads, which is what separates it from the W3 Omni; the compact Winbot Mini sits below it.
