Cleaning windows by hand is universally acknowledged as a chore. So when Ecovacs proposes to entrust this task to a robot, the idea instantly appeals. With the Winbot W3 Omni, the manufacturer doesn’t merely offer a refresh; it completely rethinks its approach, pairing it with a docking station that is much more ambitious than those of previous generations. But as Ecovacs tries to do more and more, is it possible that the company has gone too far?
- Design and finishes are meticulously crafted
- Convincing cleaning performance
- Automated self-cleaning of the wipe integrated into the station
- Practical app and LCD screen
- Approximately 3 hours of autonomy, enough for large areas
- Doesn’t clean the corners
- Heavy and not easy to transport
- Brushes wear the wipes prematurely
Ecovacs isn’t a novice in the world of window-cleaning robots. The manufacturer has already introduced several versions, but the Winbot W3 Omni represents something entirely different. Gone is the compact little docking station that housed the robot. Here, we’re dealing with a much larger, heavier station, well equipped with features.
But by aiming to offer a multitude of features, isn’t Ecovacs perhaps trying to do too much? The station can wash the cleaning cloth thoroughly, without requiring the washing machine step. The manufacturer moves from a fairly conventional model to a device with two water tanks, a color LCD screen, functions unseen in the competition, and yet—does all of this truly prove useful? We tested it for a month, and here is our verdict.
A bulky design that weighs on the scale
Whereas the previous versions, including the Ecovacs Winbot W2S Omni tested earlier, could fit inside their docking station, the Winbot W3 Omni cannot. The station is indeed massive, yet its capabilities are far greater, so the robot docks at the back of it.
This is a first, regrettable point. In pursuing more features, Ecovacs sacrificed the compactness that characterized earlier versions. At arm’s length, you’re looking at about 12.2 kilograms between components; empty, the Winbot W3 Omni already weighs a lot. When fully loaded with tanks, you’re nearing 13 kilograms. In these conditions, it will be difficult to recommend it to an elderly person or someone with limited mobility. It’s a purchasing criterion not to be overlooked.
The design, compared to the W2 Omni, is much more compact now, yet it undergoes a radical transformation. The front face adopts a washing-machine-like appearance because it is the part that cleans the microfiber used for glass. Four brushes surround the entire area and do the work as soon as the user desires.
On the top, there are two water tanks—clean and dirty. As with robotic vacuum cleaners, these tanks are used to wash the wipe, supplying water that is subsequently recovered.
Alongside this, a multitude of buttons sits next to a color LCD screen. Ecovacs doesn’t place such a display on its robot vac stations, but on the glass-cleaner Winbot W3 Omni it is present. The screen is not touch-enabled; it is controlled with the buttons on the right side.
How to store the Winbot W3 Omni? Used to previous generations, we tried to log it into the station, but that is not possible. The device attaches to the back with a small fold-out hook. It’s less convenient than in older generations, but given the XXL features, there simply isn’t space to tuck it inside.
Also notable is the presence of a suction cup under the station, which helps keep everything in place. With no less than 10 kilograms on the scale for the station, there was little doubt.
A practical app but not essential
The Ecovacs app complements the display on the device. It lets you configure the language of use and could be enough for many users. Nevertheless, the app adds a few more details for those who want them.
The app is straightforward to use. It offers features for both the robot and the station, with various cleaning parameters for glass and for the wipe, once the glass is clean.
As is typical, however, there might be a need for a software update; we had one to perform at startup.
Cleaning: good but not perfect
Using this robot is almost identical to its ancestors. The difference is that you can directly select, from the station, the preferred cleaning mode: quick cleaning, deep cleaning, or edge-only cleaning. After choosing, position the device and press the start button on the unit. This starts suction, which latches onto the glass like a suction cup.
The performance is satisfactory, though not flawless. First and most structural flaw: the shape of the device prevents it from cleaning the corners completely. Indeed, corners will never be perfectly cleaned. You’ll always need to wipe dust from the corners by hand, despite Ecovacs’s “fully automatic” claim.
With wheels that mark the boundaries of the cleaning zone and effectively encroach on the corners, you’ll still need a manual pass with a microfiber cloth on your glass.
Next, in terms of brute performance, it’s generally very good. A few stubborn stains resist the very first pass, but most traces, such as rain marks, disappear effortlessly. In “deep cleaning” mode, the Winbot W3 Omni makes two horizontal passes and one vertical pass to leave no mark of cleaning solution behind.
Important note about the cleaning solution: you may use the provided product, or a storefront window-cleaning solution. It is advisable to avoid using tap water to prevent mineral buildup clogging the nozzles in the long run.
A thorough maintenance
Maintenance is simplified compared with earlier versions. Paradoxically, it appears more complex on paper. To service this device, there is no need to send the wipe to the washing machine: it is integrated into the station itself.
It’s enough to remove the wipe’s attachment fixed by the four hooks to place it in the station’s wash chamber, whose cap opens via a button on the unit.
The washing cycle lasts about a minute. The four brushes rotate in unison and effectively remove dirt from the wipe. In practice, not having to run the wipe through a washer really changes daily life.
A key note about the cleaning solution: you can use the provided product, or a window-cleaning solution bought in-store. It is recommended to avoid tap water to prevent limescale buildup clogging the nozzles over the long term.
Ecovacs Winbot W3 Omni: Clubic’s verdict
Is the Winbot W3 Omni excessive for a real user’s needs? Ecovacs might have aimed too high? No—the performance is generally satisfying, albeit imperfect. The features are numerous, and the manufacturer has markedly improved its glass-cleaning station to become a true multifunctional hub. It’s no longer just a robot that cleans a window and can be stowed away; here, the Winbot W3 Omni takes care of cleaning its consumable itself.
Everything depends on how you intend to use it. If your goal is to wash 60-centimeter-wide windows the way you used to do with a cloth, a simpler generation would suffice. If, on the other hand, you want to clean large bays that stretch across several meters, this is an appealing choice.
The ability to swap wipes between two windows, or to wash one and reuse it after, is ideal. At €649, the Winbot W3 Omni targets a savvy audience ready to invest to get rid of this chore for good.
