Overview

The ECOVACS WINBOT mini is an 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 is ECOVACS’ most compact window cleaner, measuring 30% thinner and 37% smaller than the W1 PRO. Despite the smaller footprint, it generates 7,500 Pa of suction - the highest grip force in the WINBOT lineup. The chassis uses an ultrasonic atomization spray system that produces a fine 10-micron mist rather than standard liquid spray, reducing drips and streaks. The 9-layer safety system includes edge detection sensors, pressure sensor, UPS battery backup, and reinforced tether. The cleaning pad is a custom microfiber design sized for the compact body. The water tank is smaller than the W1 series but the atomization system uses fluid more efficiently.

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 impressive suction power (7,500 Pa) in the most compact form factor ECOVACS has ever produced. Its 7,500 Pa suction and 9-layer safety system make it a practical tool for homes with large windows or multiple stories. The ultrasonic atomization spray is a genuine innovation - the fine 10-micron mist reduces drips and streaks compared to conventional spray systems, and the compact size makes storage effortless. The main limitations are the consumable costs and the setup time required for each cleaning session. For homeowners who want maximum portability or need to clean windows in tight spaces like apartment balconies, the WINBOT mini is the best compact window cleaner we have tested.
