Ecovacs Robotics showed off the Winbot W2S Pro Omni and the Winbot W2S Pro robotic window cleaners at IFA 2026 earlier this week in Berlin.
The Winbot W2S Pro Omni offers precise edge-to-edge scrubbing, cordless cleaning, intelligent navigation, and safety features. It boasts upgraded TruEdge 2.0 technology, combining precise frame sensing with an optimized four-corner scrubbing system for more complete edge-to-edge cleaning coverage. Four active corner scrubbers use high-density felt bristles to target dirt along window borders and corners, while continuous frame detection helps it maintain stable contact with window frames and edges. Together, the four-way scrubbing system delivers up to a 46% increase in cleaning efficiency compared with the previous generation, covering up to a square metre in 90 seconds.
The Winbot can dynamically adjust its path and brush position as it encounters different window structures, helping minimize jamming and maintaining consistent cleaning coverage without manual intervention. For tougher outdoor dirt like rain stains, dust accumulation, and bird droppings, its pressurized dual-side spray technology uses three precision spray nozzles on each side.
The upgraded triple-nozzle design expands spray coverage to 90%, helping reduce dead spots while creating a fine, wind-resistant water film that loosens dirt before wiping. Combined with an ultra-fine microfibre wiping pad, the system helps lift away dust, pollen, water spots, fingerprints, smudges, and pet marks for a streak-free finish.
For larger cleaning jobs, its 4.1 fl. oz. water reservoir provides up to 807 square feet of coverage per fill, allowing you to clean more windows without repeatedly stopping to refill.
The Omni Station combines control, charging, power, and storage in one portable base. Its integrated 5,200mAh battery provides up to 110 minutes of cordless cleaning, allowing you to clean in locations where power outlets may be difficult to access, like balconies and bathrooms. The station can also connect directly to AC power for longer cleaning sessions.
A high-strength 2-in-1 compound cable combines power delivery and safety tethering in a single line and automatically retracts into the Omni Station after cleaning. When the job is done, the Winbot and its accessories can be stored inside the Omni Station, while its soft rubber handle makes the station easy to carry.
Powered by WIN-SLAM 4.0 technology, the Winbot W2S Pro Omni can adapt its path planning across a wide range of window layouts, including expansive floor-to-ceiling windows, frameless partitions, and vanity mirrors. Its multi-sensor detection system continuously monitors window frames and obstacles, allowing the Winbot to calculate a bypass strategy when it encounters obstacles like window handles or locks and continue cleaning.
Through the Ecovacs mobile app, voice control, or shortcut buttons on the Omni Station, you can choose from eight cleaning modes to suit different cleaning needs and scenarios. At just 66dB, the Winbot W2S Pro Omni is the quietest model in the Winbot family to date. Its four-layer noise reduction system combines Dual-Wing Air Ducts, vibration control, acoustic padding, and sound insulation to help deliver quieter operation.
The Winbot W2S Pro Omni features a 12-tier protection system combining hardware and software safeguards. Key protections include 10,000Pa suction power, automatic air pressure compensation, a floating wiping pad plate, anti-drop protection, and power-off protection. The automatic air pressure compensation system detects air leaks in as little as 0.007 seconds and compensates to help maintain consistent suction.
If power is interrupted or the battery level becomes low, power-off protection keeps the Winbot attached to the window for more than 30 minutes, providing additional time for you to respond.
The Ecovacs Winbot W2S Pro Omni is available for a limited time for $630, discounted from the regular price of $700. The Winbot W2S Pro is selling for a limited time for US$340, down from its regular price of US$400.
