Cleaning high-rise exterior windows has long been one of the most dangerous and tedious household chores. Streaky glass, stubborn rain marks, dust accumulated on window frames, and the risk of climbing ladders keep countless homeowners away from spotless windows. Today, ECOVACS upgrades its iconic WINBOT series and launches the WINBOT W2S PRO OMNI, a fully optimized robotic window cleaner built for modern homes, high-rise apartments, villas and commercial glass spaces. It solves long-standing pain points of traditional window-cleaning robots: incomplete edge wiping, insufficient water spray, unstable navigation and safety concerns, bringing truly reliable, streak-free, hands-free window maintenance.
At the heart of its cleaning upgrade lies TruEdge 2.0 Edge-Locking Technology. Adopting an innovative radial edge-locking structure, the WINBOT W2S PRO OMNI can actively detect window borders and frames. When approaching edges and corners, its built-in scrubber automatically drops and spins at up to 200 RPM to grind away caked dirt, grime and mould along the frame. After finishing edge cleaning, the scrubber retracts automatically to avoid secondary contamination. Unlike many competing models that leave a noticeable uncleaned gap along borders, this design delivers near-zero-gap cleaning, reaching every corner that used to require manual touch-ups. It supports framed windows, frameless glass panels and sloped glass up to ±45°, and adapts to glass as thin as 3mm, covering most residential and light commercial glass scenariosECOVACS.
Complementing the edge scrubbing system is the upgraded three-nozzle wide-angle atomization spray technology. Three spray nozzles form a wide-angle mist with up to 90% surface water coverage. The fine atomized water film dissolves bird droppings, rain stains, oil marks and dried dust before wiping, greatly reducing the chance of water streaks left on the glass. It is paired with a 120ml large-capacity water tank — a 25% increase in continuous cleaning coverage over previous generations. One full tank supports up to 75 m² of glass cleaning, perfect for villas with multiple large floor-to-ceiling windows, eliminating frequent refills during work. When matched with ECOVACS dedicated bluebell cleaning solution with ionic active ingredients, it breaks down stubborn dirt efficiently while leaving a fresh, subtle fragrance without sticky residueECOVACS.
Navigation and route planning are powered by WIN-SLAM 4.0 intelligent mapping algorithm. Multiple built-in sensors work together to scan the glass surface, identify frame boundaries and obstacles, and generate the most efficient cleaning path in seconds. Users can pick from 8 preset cleaning modes: Fast Clean, Thorough Clean, Deep Clean, Edge Clean, Spot Clean, Zone Clean, Heavy-Duty Clean and remote manual control. If the robot is interrupted mid-task, it can remember its progress and resume cleaning from the stopping point. It will automatically return to its starting position once the whole window is finished. The robot also supports real-time voice broadcast to report working status, so you know its progress without constantly checking itECOVACS
