Our verdict
The best mix of cleaning power, convenience and price in Ecovacs' 2026 range. Its close sibling, the W2 Pro Omni, scored 5 out of 5 for performance from TechRadar.
What we like
- Portable station holds the battery, so you can clean away from sockets
- Eight cleaning modes including edge and heavy-duty
- Detects frames, handles and locks
- Ecovacs says it is its quietest Winbot
What to know
- Still leaves a small strip at the very edge, a limitation of all window robots
- Premium price
