ECOVACS WINBOT W2 PRO Window Cleaning Robot, 3 Nozzles Water Sprayer, 10-Level Protection, Win-SLAM 4.0 Path Planning, Steady-Climbing, Edge Detection, App Control

I was somewhat skeptical when I bought this, but I have a huge wall of windows in my home, 10 feet high, and cleaning them has always been a struggle. This machine really works - I was pleasantly surprised. You simply fill up the solution, dampen the microfiber pad, attach it to the bot, activate the bot while it's pressed against the glass and off it goes, covering and thoroughly cleaning the entire pane. Selecting the cleaning program using the app is simple. Manually controlling the bot using the app isn't quite so simple but there really shouldn't be much need for that, as the cleaning programs do the job perfectly. I did not have to manually go back over any spots after the bot was done. The bot comes with a small bottle of branded solution. That's what I used and it works perfectly. Instructions state you can use other types of solutions - even home-made ones - but I played it safe and found a refill bottle of the branded solution from another online source (it does come from China and takes a bit of time). This solution cleans really well and leaves absolutely no streaks so I wanted to stick with what I know works. I should add that my windows are large, floor to ceiling "window wall" panels (I live in a high rise), for which this bot is well-suited...large rectangular panes with no protrusions from the framing. If you have smaller and/or more separated windows (i.e. lots of framing), I could see this being a bit more cumbersome to use - lots of stops/starts. Likewise, if you have protrusions from the glass edges/framing that the bot would need to navigate around (i.e. window cranks, locks, etc.) that would leave some spots still dirty requiring you to take care of those manually after the bot is done. But, if you have large panes of glass, especially tall ones that would require you to get on a ladder to clean, this bot is the perfect solution.

The machine is very helpful cleaning tall windows and large sliding glass doors. The device sticks securely to the glass and glides smoothly across the surface, leaving the windows streak-free. It does a great job mapping the window area, and the app is very easy to use with several cleaning modes to choose from. Noise-wise, not silent, but definitely manageable. The build quality feels solid and durable.

This is my first window-cleaning robot, and the Ecovacs Winbot W2S has impressed me. I have the standard W2S model, not the W2S Omni with the portable battery pack. Its 26‑foot power cord (10 feet from outlet to the compound connector with the safety harness, plus another 16 feet) makes it easy to handle tall windows and outdoor glass railings. It’s a great tool for keeping windows clean between annual power washes. It doesn't deliver absolute perfection, but it makes a substantial difference with minimal effort. For most people, that’s what they need and want. Our tall windows and glass deck railings hadn’t been cleaned since Covid and were extremely dirty. I plugged the robot in indoors, ran the long cord out to the deck, and let it work. Over one afternoon, I ran roughly 40 “thorough” cycles (twice per side, per window, because the glass was so neglected). I wasn’t expecting spotless results or perfect navigation, but the W2S handled the job far better than I anticipated. I used the same cleaning pad for all these cycles (two pads are included). After each run, I rinsed the pad in the kitchen sink and hand wrung it out until no more water dripped. I also wiped down the blue edge‑cleaning wheels and the treads with a pet/baby wipe, since both collect a lot of grime. The W2S’s updated edge‑cleaning wheels and triple‑nozzle spray help it pick up dirt pushed outward by the pads during cleaning. It runs a dedicated edge pass at the end of the cycle to remove most of that buildup. The window corners still retain a bit of dirt, and the robot leaves a damp square impression where it detaches (sometimes that cleanly evaporates). The improvement in my window clarity and cleanliness was dramatic (see photos). Some Winbot owners report streaking, but I didn’t see any streaks during my use. To keep it that way, I plan to stick with the official cleaning pads ( like this ) and the official cleaning solution ( like this ). So far, I’ve only rinsed the pad with tap water between cycles. While the pad is slightly stained now, that doesn’t seem to affect cleaning performance. Therefore, I'm not going to wash the pad with soap or other cleaners in case that is why some customers see streaks. I only gave my W2S 4 stars because it experienced the occasional fault and had some limitations in my environment. It often doesn't return exactly where it started, so use the app's manual control if you can't reach it after the cycle. My glass railings are attached to the deck without a clear glass edge, so the robot gets confused and occasionally got stuck. It also got stuck on one of my glass doors (see video). When this happens, it doesn't complete the cycle with the normal edge-cleaning run. I also got a couple loss-of-pressure warnings in the beginning, but that may have been because I didn't accurately attach the pad before each run. After that, I spent more time carefully placing and positioning the pad across the velcro spots and didn't see that error again.

This is such a beautiful item. It has made my life so easy going. No need to climb and clean windows any more. I just stick it and so easy to use. Cleans every corner and the suction power is the best. My robot family has a new member now and indeed my favorite one

Me encantó, funciona muy bien, ayuda para mantener la limpieza de los vidrios, si hay manchas de pintura o algo muy pegado, no lo quita, solo mantiene limpio, me encanta.

I love this product

Excellent cleaning

Excelente Robot limpiavidrios. Muy eficiente.

The mains cable supplied with this product arrived with a USA plug. Since I cannot find any way to contact the supplier, I cannot use the device and so I am returning it. Given the substantial cost of the unit it is not realistic to source and pay for a new cable or converter.
