Works well
Overall - happy with my purchase. Windows come up well after cleaning, easy to use and long usage between charges. Worth getting some extra cleaning pads so that they're always clean.

Works well
So far so good with the window robot. It does exactly as it says on the box - washes windows automatically. That said, it’s amazing if it’s used consistently - windows look great. If the window is extra dirty, it may require multiple cycles AND wash pads. Overall, happy with the purchase.

Well designed except for power cord management. Build quality fair. Need to be nearby when operating. Cleaning performance very good.

At a glance
A premium robotic window cleaner designed for households that want safer, easier cleaning of indoor and outdoor flat glass. It stands out for its portable OMNI station, auto spray system, strong suction and smart path planning. It is especially handy where power points are awkward or unavailable. The main limitation is that it is made for flat window surfaces rather than more specialised or irregular glass cleaning jobs.

Things to consider
Best suited to flat glass surfaces, so it is less versatile than specialist solutions for irregular, heavily framed or non-flat window areas.
Pet hair performance score
1/10 - this product is designed for window cleaning rather than picking up pet hair from floors or furnishings.
Smart home integration score
6/10 - app-based control and mode selection are supported, but no voice assistant support is specified here.
Carpet vs hard floor suitability
Not applicable - designed for flat window and glass surface cleaning, not floor cleaning.
Noise level vs category average
7/10 - at 63 dB, it is relatively quiet for an active robotic cleaner.
Allergy friendliness
Moderate - helps remove dust and grime from glass surfaces, but it is not a floor vacuum or air-filtration solution.
Key benefits
- Portable OMNI Station: Lets you clean windows more freely by providing portable power and storage in one station.
- Three-nozzle Wide-angle Spray Atomization: Delivers broader, more even moisture coverage to help reduce streaks while cleaning.
- WIN-SLAM 4.0 Path Planning: Increases cleaning efficiency by 30% for faster, more systematic window coverage.
- Edge Cleaning Mode: Improves edge-cleaning efficiency by 65% to better reach window borders.
- 2800 Pa Suction Power: Helps the robot stay attached securely while cleaning vertical glass surfaces.
- 110-Minute Battery Runtime: Covers up to 55 m² per charge, making it practical for larger glass areas.
- Quiet Operation: Runs at 63 dB, helping keep window cleaning less disruptive in everyday home use.
- Multiple Cleaning Modes via App: Makes it easier to tailor cleaning to different window conditions and routines.
Q: Can the Ecovacs Winbot W2 Pro OMNI clean windows where there is no nearby power point?
A: Yes. The OMNI Station has an integrated lithium battery, so the W2 Pro OMNI can clean glass in areas without direct access to a power point. ECOVACS states up to 110 minutes per charge, covering about 55 square metres in typical use.
Q: Is the Winbot W2 Pro OMNI suitable for frameless glass, shower screens or glass balustrades?
A: Yes. This model is designed for flat glass surfaces, so it can suit more than standard window panes, including frameless glass and shower screens. It is not intended for heavily textured, curved or uneven surfaces where suction and pathing can be affected.
Q: How well does the Winbot W2 Pro OMNI handle window edges and corners?
A: It is built for stronger edge coverage than earlier designs, with an edge cleaning mode that ECOVACS rates as 65% more efficient. On flat panes it can clean close to edges well, but deeply recessed frames or thick seals may still limit reach.
Q: Will the Ecovacs Winbot W2 Pro OMNI remove heavy grime in one pass?
A: Not always. The three-nozzle spray and intelligent pathing help with built-up dirt, but very dusty or neglected glass may need more than one cycle. For best results, especially on larger panes, use clean pads between runs rather than expecting one-pass perfection.
Q: Do you need the app to use the Winbot W2 Pro OMNI?
A: No. The OMNI Station works as a control panel, so the robot can be operated without relying on the app for every clean. The ECOVACS HOME App is mainly useful for selecting cleaning modes and adjusting how the robot tackles different glass areas.
Q: Can the Winbot W2 Pro OMNI cope with window hardware such as latches or small obstacles?
A: It can handle some minor interruptions better than basic window robots because it uses WIN-SLAM 4.0 planning and an intelligent climbing system. Even so, larger protruding hardware or uneven sections can interrupt coverage and may need a manual touch-up afterwards.
