Prices last checked June 2026
Overview
The ECOVACS WINBOT W2 PRO OMNI is an 8.6-rated robotic window cleaner designed to automate the tedious task of glass cleaning on residential windows. Priced at $399, it features 5,500 Pa of suction to grip vertical and inclined glass surfaces securely. Its key differentiator is portable OMNI station, 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 W2 PRO OMNI introduces the portable OMNI station - a battery-powered base station that provides extended 130-minute runtime and houses the cleaning solution, making it the only WINBOT that can clean multiple floors without returning to a fixed wall outlet between sessions. The rectangular robot chassis generates 5,500 Pa of suction and features WIN-SLAM 4.0 navigation sensors. The 12-layer safety system is the most comprehensive in the lineup. The OMNI station includes a 5,200 mAh battery and an auto-spray system that delivers 70 g/min at 43.7 kPa. The cleaning pad is a larger microfiber design optimized for the W2’s wider cleaning path.
Performance
We tested the WINBOT W2 PRO OMNI 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 5,500 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 W2 PRO OMNI 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 12-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
- 5,500 Pa suction holds securely on vertical glass - edge sensors detect window frames in 0.02 seconds
- Portable OMNI station with 5,200 mAh battery enables multi-floor cleaning without wall outlet tethering
- 12-layer safety system with UPS backup, pressure sensor, edge sensors, and reinforced tether
- 130-minute runtime from the OMNI station battery covers entire homes on a single session
- WIN-SLAM 4.0 navigation provides S-shaped cleaning pattern with 90% streak-free results per clarity meter tests
Cons
- At $399, the premium over the W2 OMNI ($349) for the battery-powered station may not be worthwhile if you only clean ground-floor windows
- Portable OMNI station adds bulk and weight compared to the simpler W2 OMNI setup - less convenient to store
- Cannot clean very small or oddly shaped window panes under roughly 12 x 12 inches
- Consumable pads and ECOVACS cleaning solution add recurring cost over time
Verdict
The ECOVACS WINBOT W2 PRO OMNI earns a 8.6 out of 10, delivering class-leading window cleaning performance with the unique advantage of a battery-powered OMNI station. Its 5,500 Pa suction and 12-layer safety system make it a practical tool for homes with large windows or multiple stories. The portable OMNI station is the key differentiator - it provides 130 minutes of runtime from the station battery, allowing multi-floor cleaning sessions without re-tethering to a wall outlet. The main limitations are the consumable costs and the additional bulk of the portable station. For homeowners who need to clean windows on multiple floors in a single session, the W2 PRO OMNI offers unmatched freedom of movement among tethered window cleaners.
