Overview

The ECOVACS WINBOT W1 PRO is a 7.8-rated robotic window cleaner designed to automate the tedious task of glass cleaning on residential windows. Priced at $399, it features 2,800 Pa of suction to grip vertical and inclined glass surfaces securely. Its key differentiator is dual cross auto-spray system, 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 measures 295 x 148 x 139 mm and weighs approximately 1.65 kg with the water tank filled, making it compact enough for windows as small as 350 x 350 mm. The rectangular chassis houses a 60 ml water reservoir, dual cross spray nozzles, and WIN-SLAM 3.0 navigation sensors in a streamlined package. The cleaning pad uses microfiber material that traps dirt without scratching glass, and the 8-layer safety system provides redundant fall protection. The safety tether attachment point with carabiner clip is reinforced and inspires confidence during upper-story use, though the 5.5-meter power cable must be managed carefully for each session.

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 spray system distributed cleaning solution evenly across the glass surface with good coverage. 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 W1 PRO include the ECOVACS HOME App (iOS/Android) and on-device buttons for starting, stopping, and directing the robot. The app provides three cleaning modes: Fast mode (a single pass for light dust), Deep mode (overlapping passes for heavier grime), and Spot mode (concentrated area cleaning). A real-time cleaning path visualization shows where the robot has cleaned, and scheduling lets you set recurring window cleaning times. Safety is a primary focus: the 8-layer system includes four edge detection sensors that prevent the robot from over-running window frames (0.02-second response time), 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 UV-resistant power cable is 5.5 meters long and should be managed carefully during setup to avoid snagging.

Pros

• 2,800 Pa suction holds securely on vertical glass and inclined skylights
• Dual Cross Auto-Spray distributes cleaning solution evenly with no pooling
• 8-layer safety system with UPS backup keeps robot attached during power loss
• WIN-SLAM 3.0 navigation follows methodical S-shaped pattern with 90% streak-free results
• EDGE mode sensor responds in 0.02 seconds to prevent over-running window edges

  Cons

• At $399, it costs more than entry-level window bots like the HOBOT-268 and requires a commitment to a niche appliance
• 5.5-meter power cable requires careful routing and limits reach on very large windows
• Cannot clean windows smaller than 350 x 350 mm or oddly shaped panes like arches or portholes
• Replacement microfiber pads and ECOVACS cleaning solution add recurring cost over time

  Verdict

  The ECOVACS WINBOT W1 PRO earns a 7.8 out of 10, delivering solid window cleaning capability at a mid-range price point. Its 2,800 Pa suction and 8-layer safety system make it a practical tool for homes with large windows or multiple stories. Unlike the smaller HOBOT-268 (which uses fan suction at 2,500 Pa) or the premium HOBOT-388 (with simultaneous spray-scrape-clean action), the WINBOT W1 PRO strikes a balance between suction power and compact size for residential use. The main limitations are the ongoing consumable costs for pads and cleaning solution, plus the setup time required each session. For homeowners who dread ladder-based window cleaning, the ECOVACS WINBOT W1 PRO offers a genuine labor-saving alternative with comprehensive safety features that competing models at this price often lack.
