- Yes
The pick for small and narrow windows, since its 21.5 cm body fits panes that bigger Winbots cannot. It is corded and has no station, so you carry it, plug it in and rinse the pad yourself. Skip it if you mostly have big picture windows, where the cordless models finish faster.

- Three nozzle spray
- Backup battery
- 3,000 mAh battery
- Frameless
- Supported
The cheapest way into the W2S line, with the same suction claim and edge scrubber as the Omni. KultureGeek found it cleaned indoor glass well in one pass but noted you manage the cord yourself. Check what is in the box before buying, since Ecovacs US does not list the contents.
