A practical appliance like this one, which they just don't seem to develop any more, but this washer is now the best invention in my opinion: D Even though the apartment is on a corner, I was able to avoid getting a headache because the windows face the street and need to be washed frequently. Once you have finished washing all of the windows, you can go around the apartment in a clockwise direction. Even though we weren't able to figure out how to use it properly right away, the reviews and the technical support were quite helpful. I also tried to wash the mirror, and everything went swimmingly. I haven't yet reached the floor, but as soon as I do, I'll use this washer to clean it. Everything turned out to be as easy as a piece of cake. It leaves no streaks on the windows, and it doesn't fall over.
