The cable length (plug) is 1.5m, but the hose length (connection to the window cleaner, so to say fuse) is 5.5m.

Yes, you can also use the appliance to clean glass roofs, as it is suitable for use on large glass surfaces and balconies. Whether cleaning upside down is possible is not explicitly confirmed in the official sources - the information refers to universal glass surfaces, but not to the specific function of working upside down. For safe use, we recommend checking the operating instructions or asking the manufacturer.

The Winbot W2 Pro Omni is mainly designed for vertical window surfaces. Use on glass roofs with a slope of 10 degrees could be problematic as the robot may not provide the same grip as on a vertical surface. It is recommended to consult the instruction manual or the manufacturer to ensure that the robot works safely and effectively in this position.

I can't say - so far the Winbot has only travelled vertically (180 degrees). What certainly doesn't work is travelling horizontally, an error message appears. I would ask Ecovacs directly - better safe than sorry!

The Winbot W2 Pro Omni cannot move independently from one glass railing to the next, especially if there are small gaps between the glass panes. The robot is designed to work systematically on a glass surface and does not travel over window frames or edges. It must therefore be moved manually from one glass to the next if they are not directly connected.

I have no idea, the device is brand new and works perfectly

The Winbot W2 Pro Omni can also be used without a docking station as it is battery-powered. However, the docking station offers additional functions such as a larger battery capacity and improved safety features, which makes it advisable to use it with the docking station.

These replacement cleaning pads should fit: https://www.galaxus.ch/de/s2/product/ecovacs-w-cc02-0009-fensterreiniger-zubehoer-42500316.

The length of the cable between the battery station and the Winbot is not explicitly stated in the available information. However, the docking station has a combination cable that can extend up to 5.5 metres and can withstand a pull of 100 kg.

Our windows are very clean and we see absolutely no "smearing", even when the sun shines on the windows. When I used to clean the windows by hand, I often had smear marks. I have much better results with the robot. Please note that the wiping pad must be well moistened with water - see instructions. So far, we have only used the original cleaning agent and, despite the relatively high price, I have no desire to experiment with other liquids - the results are too good for that.
