If you dread streaks, ladders, and hours spent scrubbing windows, a robotic window-cleaning helper can be a game changer. The ECOVACS Winbot W1 Pro brought intelligent cleaning with auto-spray and edge detection, but the newer Winbot W2 advances performance, navigation, and cleaning power. Below is a detailed, buyer-focused comparison — and why Winbot W2 is the smarter choice overall.
Winbot W2 significantly improves on the W1 Pro with stronger cleaning capability, smarter navigation, faster operation, and upgrades in edge handling and spray power. Both models automate window cleaning, but W2’s refinements — like better obstacle detection and broader cleaning coverage — make it the more capable partner for homes with many or large windows.
Why Do I Recommend ECOVACS Winbot W2?
- Stronger suction & cleaner windows: Winbot W2 boosts suction force up to 5500 Pa and combines optimized spray volume and pressure for more effective stain removal than the W1 Pro’s 2800 Pa output. That means better adherence to glass and deeper cleaning.
- More efficient intelligent navigation: The W2’s upgraded WIN-SLAM™ 4.0 path planning and faster travel speed help it cover glass surfaces more quickly and thoroughly, reducing clean time and leaving fewer streaks.
- Improved obstacle detection & safety: Compared to the W1 Pro, the W2’s sensors detect obstacles above 4 mm, nearly 100% better accuracy, which increases safety and reduces errors during operation.
- Higher spray coverage & speed
- Thanks to a larger spray volume and enhanced water pressure, W2 distributes cleaning fluid more effectively across the glass, reaching up to 70 g/min compared to W1 Pro’s 30 g/min. This improves how deeply it dissolves grime.
- Modern design and smarter planning: Built-in improvements like a refined sync belt and advanced self-compensation systems help prevent falls and adapt to different window conditions, making the W2 more resilient and versatile.
