ECOVACS WINBOT window cleaning robot line

In late June 2026 ECOVACS introduced its newest autonomous window‑cleaning device, the WINBOT W3 OMNI, featuring an integrated auto‑spray system that applies cleaning fluid automatically as the robot traverses glass surfaces.

A month later a product review examined the earlier WINBOT W2S OMNI model alongside Kärcher’s cordless handheld window‑vacuum. The WINBOT W2S OMNI uses suction to cling to the pane and a dual‑wing spray to wet the glass, with microfiber pads removing dirt. Reviewers praised its lightweight design and edge‑cleaning capability but noted reduced effectiveness on heavily soiled windows, the need to relocate the robot between panes, and occasional light‑angle streaks. By contrast, the Kärcher device relies on manual spraying and wiping, delivering consistently streak‑free results but requiring user effort for each window and limited by battery life.

Both entries illustrate the market’s move toward semi‑automated home‑cleaning solutions, highlighting the trade‑off between full automation and manual control in domestic window maintenance.
