I hate cleaning windows. But it must be now times. Looking for a device that promises minimal effort and maximum effect, I came across the Kärcher window vacuum cleaner - and now I am happy that I have him. Shortly moisten with a spray bottle the discs over it with the puller and then suck the dirty water. The result: streak-free windows. In the corners I have sometimes even dry with a paper towel, but overall my teeth now goes much faster by hand. And above all, I have a lame arm no longer so fast. The 50 euros were well spent.
