Cleans the windows well, not the edges very well. If the windows are very dirty, you need to clean the cloth frequently. It goes without saying that the glass should not have any stickers, etc

After researching, I ended up with this particular machine. I have a professional space with many windows that are not accessible from anywhere, so I needed to find an automatic solution. This device does exactly what it promises. I didn't expect it to work so well. It sticks and doesn't fall. You also put the special liquid in the container so it sprays by itself. I had very dirty windows, and I helped it by spraying liquid directly onto the glass as much as I could. It may leave some marks sometimes or at the edges of the windows. But that's for the detail-oriented. It frees up your hands. You place it from window to window and forget about it in between. If the windows are very dirty, you just set it for 2 cycles to clean or start over. Sometimes it may get stuck in corners and block. With the remote function, you control it from your phone. It's very easy and functional.

Unbelievable tool! Suction cup on the glass is amazing! Cleans exceptionally - if the windows are very dirty, just rinse the cloth and repeat the process. I live on a floor without a balcony and the windows were impossible to clean. I was saved. Expensive, but worth the money!
