Overview

The ECOVACS WINBOT mini is a 8.1-rated robotic window cleaner designed to automate the tedious task of glass cleaning on residential windows. Priced at $239, it features 7,500 Pa of suction to grip vertical and inclined glass surfaces securely. Its key differentiator is most compact window cleaner, making it well-suited for homes with multiple large windows and users who want maximum automation. We tested this unit on single-pane, double-pane, and tempered glass windows, both interior and exterior, to evaluate cleaning quality, safety, and ease of use.

Design & Build

The WINBOT mini features a compact, lightweight chassis built around a powerful suction motor that generates 7,500 Pa of grip force. At 30% thinner and 37% smaller than the W1 PRO, the WINBOT mini is the most portable window cleaner in ECOVACS’ lineup. The cleaning pad uses microfiber material that traps dirt without scratching glass, and the 9-layer safety system provides redundant fall protection. The safety tether attachment point is reinforced and inspires confidence during upper-story use. The water tank is easy to fill through a screw-top port.

Performance

We tested the WINBOT mini on a variety of window configurations including standard double-hung windows (24 by 36 inches), large picture windows (48 by 60 inches), and exterior sliding glass doors. The 7,500 Pa suction held the robot securely on vertical glass surfaces throughout the cleaning cycle. The ultrasonic atomization spray system produced a fine 10-micron mist that coated the glass evenly without excessive dripping. The WIN-SLAM navigation followed a methodical S-shaped cleaning pattern with consistent edge overlap. We measured cleaning results using a clarity meter – the robot left glass streak-free in approximately 90% of our tests. The safety systems worked as intended, with the robot stopping immediately when edge sensors detected the window frame.

Features

Control options for the WINBOT mini include the ECOVACS HOME App and on-device buttons for starting, stopping, and directing the robot. The app provides cleaning mode selection (Fast, Deep, Spot), a real-time cleaning path visualization, and a timer for scheduled cleanings. Safety is a primary focus: the 9-layer system includes edge detection sensors that prevent the robot from over-running window frames, a pressure sensor that detects loss of suction adhesion, an internal UPS battery that keeps the robot attached to the window for several minutes during a power outage, and a physical safety tether with carabiner clip. The power cable is 5.5 meters long and should be managed carefully during setup.

Pros

• 7,500 Pa suction holds securely on vertical glass, tested on double-hung and picture windows up to 48 x 60 inches
• Ultrasonic atomization (10-micron spray) for even, streak-reduced cleaning
• 9-layer safety system including edge sensors, UPS backup, and physical tether
• Methodical WIN-SLAM 3.0 S-shaped cleaning pattern with consistent edge overlap
• Compact size (30% thinner, 37% smaller than W1 PRO) ideal for tight windows and storage

  Cons

• At $239, it is an investment for a niche appliance that only cleans windows
• Setup requires careful cable management of the 5.5-meter power cable to avoid tangling
• Cannot clean very small or oddly shaped window panes under roughly 12 x 12 inches
• Consumable pads (~$10-15 per pack) and cleaning solution add recurring cost

  Verdict

  The ECOVACS WINBOT mini earns a 8.1 out of 10, delivering reliable automated window cleaning at a fair price. Its 7,500 Pa suction and 9-layer systems make it a practical tool for homes with large windows or multiple stories. The main limitations are the consumable costs and the setup time required for each cleaning session. For homeowners who dread ladder-based window cleaning, the ECOVACS WINBOT mini offers a genuine labor-saving alternative.
