What is the ECOVACS WINBOT W2 PRO OMNI?
The ECOVACS WINBOT W2 PRO OMNI (WG851) is the brand's high-end window cleaning robot and the 2025 version of the successful WINBOT series. It combines 5,500 Pa of suction with a holding force of over 800 N and cleans for up to 110 minutes on battery power (approx. 55 m² in quick mode) – recharged via the included portable 6-in-1 station, which can even top up the battery during cleaning. WIN-SLAM 4.0 navigation plans the route across the pane and is said to clean up to 37% more efficiently than its predecessor. Three spray nozzles and an oscillating microfibre mop (with 230 ml of solution) handle the cleaning. The Ecovacs Home app controls the robot with a 360° remote control and offers OTA updates. A 12-level protection system with eight hardware anti-drop safeguards and, according to the manufacturer, accidental damage insurance is on board.
ECOVACS positions the WINBOT W2 PRO OMNI as the high-end model of the WINBOT W2 series: instead of a power cable on the glass, it relies on an internal 4,500 mAh battery and a portable 6-in-1 station that can be placed in any room. Searching online for an "Ecovacs window cleaning robot" quickly surfaces the whole WINBOT family – from the W2S OMNI with TruEdge edge cleaning to the W3 OMNI with automatic pad cleaning.
Also worth a look: our lubluelu CHYW201 review
Looking for a budget alternative? In our second review we tested the lubluelu CHYW201 – a cordless window cleaning robot with 6,500 Pa suction and an emergency battery at a fraction of the price.
5,500 Pa Suction, 110 Minutes of Battery & the 6-in-1 Station
Here's how the ECOVACS WINBOT W2 PRO OMNI works on your window – on battery power and with a portable charging station.
Three-Nozzle Spray Technology
Three spray nozzles distribute water and cleaning solution finely across the glass, and a magnetically oscillating microfibre mop lifts the dirt and moisture back off.
800 N Holding Force & 5,500 Pa
With over 800 N of holding force (manufacturer's figure) and 5,500 Pa of suction, the robot grips smooth window glass from 30 × 40 cm reliably.
WIN-SLAM 4.0 Navigation
WIN-SLAM 4.0 path planning organises the route across the pane and is said to clean up to 37% more efficiently than its predecessor.
12-Level Protection System
Twelve protection levels including eight hardware anti-drop safeguards and an emergency battery are designed to prevent the robot from falling.
Cleaning Performance, Features & Controls
Water Tank and Cleaning Modes
Cleaning uses a 60 ml tank inside the robot, which delivers water to the glass through three nozzles; the 230 ml of cleaning solution from the box is applied to the microfibre mop. Seven cleaning modes are available: Quick, Deep, Thorough, Edge, Spot, Zone and High Performance. Testing shows that dried-on dirt is not always fully removed – and the small tank capacity means frequent refilling.
Controls: App and Station Instead of a Remote
The WINBOT W2 PRO OMNI is controlled via the Ecovacs Home app with a 360° remote control as well as via the 6-in-1 station. A separate remote control is not included; if you prefer a classic remote, keep that in mind before buying.
Noise Level
At 63 dB(A), the WINBOT W2 PRO OMNI runs noticeably quieter than older WINBOT models, which were rated at around 76 dB(A) – a plus when cleaning in living spaces.
Glass Compatibility
The robot is designed for smooth window glass from 30 × 40 cm and from 3 mm thickness; frames from 2 mm are detected. According to the manufacturer it is not suitable for textured glass, gaps, skylights or irregular windows.

In return it costs the most and does without the TruEdge edge cleaning that its sibling W2S OMNI brings – a point worth factoring in for windows with visible edges.
Who Is the WINBOT W2 PRO OMNI For?
Demanding households with many large, smooth windows who want brand quality, long battery life and app control and are prepared to pay the highest price in this comparison class.

FAQ About the ECOVACS WINBOT W2 PRO OMNI
Our Verdict
The ECOVACS WINBOT W2 PRO OMNI plays in the high-end class of window cleaning robots: over 800 N holding force, 5,500 Pa suction, 110 minutes of battery life and the portable 6-in-1 station that also charges during cleaning make it a comfortable companion for many large windows. The high price, the missing TruEdge edge cleaning and the small 60 ml tank prevent a top score. If you want maximum edge cleaning or automatic pad care, the W2S OMNI or W3 OMNI are the stronger siblings.
