It probably depends on the size of the gaps.
However, since the robot sucks itself up to the window with negative pressure and stops the cleaning process as soon as it no longer holds firmly to the window, I doubt that it will overcome gaps unless they are so small that it has no effect on the density during suction.
It needs an end point on the left, right, top and bottom like a window frame, otherwise it will not work properly and may crash. There must also be no gap between the windows, otherwise it loses its grip. It's great for large windows, we wouldn't give it away again.
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 has an internal battery that allows it to operate without a power connection, whereas the Winbot W2 Omni must always be connected by cable. The Pro has a higher suction power (5500 Pa versus 2800 Pa) and a more effective water spray system. Navigation is also more advanced on the Pro thanks to WIN-SLAM 4.0 technology (compared to 3.0 on the base model) and has more security levels. The Pro's base station is multifunctional with cable management, while the base model's is simpler. The Pro costs more, but offers superior performance and convenience.
The main difference between the Ecovacs Winbot W2 Omni and the Ecovacs Winbot W2 Pro Omni lies in the additional functions and features. The Winbot W2 Pro Omni offers a portable station with an integrated battery, a two-in-one cable for safety and power supply and automatic cable management. It has a 12-level protection function that includes more hardware-based protection measures. In addition, the Winbot W2 Pro Omni has a longer battery life and more efficient cleaning thanks to WIN-SLAM 4.0 technology. The price difference of CHF 104 reflects these advanced functions.
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.
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.
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.
