Overview

The ECOVACS WINBOT W1 Pro is a 7.0-rated robotic window cleaner designed to automate the tedious task of glass cleaning on residential windows. Priced at $299, it features 2,800 Pa of suction to grip vertical and inclined glass surfaces securely. Its key differentiator is the combination of 2,800 Pa suction, WIN-SLAM 2.0 navigation, and a 6-layer safety system at a $299 price point - making it well-suited for apartments, tight window spaces, and users who prioritize compact storage. 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 W1 Pro features a compact, lightweight chassis built around a powerful suction motor that generates 2,800 Pa of grip force. The rectangular body measures 29.5 x 29.5 x 14.2 cm and houses a water reservoir, spray mechanism, and navigation sensors in a streamlined package. The cleaning pad uses microfiber material that traps dirt without scratching glass, and the 6-layer safety system provides redundant fall protection: edge detection sensors to prevent over-running window frames, a pressure sensor to detect suction loss, an internal UPS battery for power-outage adhesion, and a reinforced physical safety tether with carabiner clip. The water tank holds 50 ml and is easy to fill through a screw-top port.

Performance

We tested the WINBOT W1 Pro 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 2,800 Pa suction held the robot securely on vertical glass surfaces throughout the cleaning cycle. The single spray nozzle distributed cleaning solution evenly across the glass surface from the 50 ml reservoir, providing approximately 2 cleaning passes before refill. The WIN-SLAM 2.0 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 W1 Pro include the ECOVACS HOME App and on-device buttons for starting, stopping, and directing the robot. The app provides cleaning mode selection (Fast for quick passes, Deep for thorough cleaning, Spot for targeted sections), a real-time cleaning path visualization using WIN-SLAM 2.0, and a timer for scheduled cleanings. Safety is a primary focus: the 6-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

• 2,800 Pa suction holds securely on vertical and inclined glass surfaces up to 90 degrees
• Single spray nozzle with 50 ml reservoir delivers even cleaning solution coverage
• 6-layer safety system: edge sensors, pressure sensor, UPS backup, and tether
• WIN-SLAM 2.0 navigation follows methodical S-shaped pattern with consistent edge overlap
• 45-minute runtime covers standard 24x36 inch windows in a single charge
• Fast, Deep, and Spot cleaning modes for different window conditions

  Cons

• $299 price is significant for a niche appliance used weekly at most
• Setup requires careful management of the 5.5 m power cable
• Cannot clean windows smaller than 24x24 inches or oddly shaped panes
• Replacement microfiber pads ($10/pair) and cleaning solution add recurring cost

  Verdict

  The ECOVACS WINBOT W1 Pro earns a 7.0 out of 10, delivering solid robotic window cleaning capability at a mid-range price point. Its 2,800 Pa suction and 6-layer safety system make it a practical tool for homes with large windows or multiple stories - areas where traditional ladder-based cleaning is dangerous or impractical. Compared to the Hobot-268 ($349, higher suction but no app control) and the Cop Rose ClearBot S1 ($259, lower build quality), the WINBOT W1 Pro strikes a good balance of safety features, navigation intelligence, and price. 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 WINBOT W1 Pro offers a genuine labor-saving alternative.
