When I asked one of our window cleaner in the company, so you get the windows clean so great, he gave me the tip with a professional built-in washer () and a stable squeegee. The choice fell quickly on the tools of Leifheit and I'm really excited.
The Window cleaning is now fast, thorough and above all done without leaving streaks at minimal effort.
Together with the Leifheit Cleaning Concentrate () I achieve great results now like a pro!
