brush One thing ... window makes (at least for me) not fun whether with without Kärcher window cleaner!
BUT
The Karcher Window cleaning I felt much easier by hand. We have previously lived in a small apartment, where I cleaned in 5 years maybe 3 times windows and not even to extract. Now we have a home and a site where the sun the whole afternoon seems pure, that is ... you see any but really each spot, point, crumbs ... the settles on the disc. After my first attempt futile putz I had again and again I've tried streak with tips and tricks, and they were clean but not free of streaks. Finding: I have no talent for cleaning windows!
Bought So Kärcher window cleaner and tested immediately. The first attempt at the first window was so great that I was thrilled that subsequent attempts were somehow 'lala' and I realized that was the first attempt probably just luck and I will still need a little practice. I went to all the windows and during the window times forgive on where the sun does not seem as strong a side purely Schlierer that was on the sunny side, of course, not as written above. However, it has had worked wonderfully when I immediately disconnect after again wiped with a clean kitchen towel over the window. Windows are simply top clean. What I had to do, however, with all windows is wipe with a cloth on the disc to the edge, but that was no problem for me.
I would recommend him. :-) Besides you can also so super clean good window, then I think you do not need it necessarily. :-)
