The 10,000 Pa Winbot with the biggest tank: TruEdge 2.0 cleaning flush to the frame, 120 ml for 75 m² a fill, four-stage noise reduction to 66 dB and a battery station for 110 minutes off the mains.

Our verdict
The W2S PRO OMNI is the top of the Winbot range, and the sheet shows it. Suction reaches 10,000 Pa in standard mode and 3,300 Pa while moving, with automatic pressure compensation; the 120 ml tank is double the W2 PRO's and Ecovacs rates it for 75 m² on one fill, with a high-pressure pump spraying for 90% water coverage; and TruEdge 2.0 uses a radial edge-locking structure to clean flush to the frame, where the W2S OMNI stops 1.1 cm short. It detects an obstacle from 2 mm, remembers its cleaning path, works on panes tilted up to 45°, offers eight modes including remote steering, and four-stage noise reduction brings it to 66 dB. The station carries a 5,200 mAh battery for 110 minutes without a socket, about 72 m² in fast mode, winds its own composite cable, anchors at over 800 N and keeps the robot on the glass for 30 minutes after a power cut. At 2.1 kg it is the heaviest Winbot, and no maximum pane size appears in its specification.
