Karcher WV 7 Signature Line

Maybe I'll end up liking window cleaner this way, haha. It's easy, fast and efficient. Once you get the trick, the result is streak-free. The trick is to use enough soapy water and minimal overlap in the strips, otherwise it will not absorb soap/water, but nothing and you will get lines. Once you get the hang of this, it's super easy. Very satisfied. 100 minutes of battery life is more than enough to wash the entire house in terms of windows. Inside and outside (approx. 25 windows).

As my friend said, after she had recovered from laughing after opening the package, 'what a great help that will be when you start washing the windows!' And indeed, it certainly does not disappoint! Just screw together the kit and throw the manual professionally into the paper pack, and you're good to go. With the spray bottle it is easy to quickly soak the windows and then quickly run the plunger over it. It takes a little bit of practice to get it completely streak-free, but once you get the hang of it, it is a very nice tool indeed! A bit on the heavy side, and that might be fun if I balance window number 6 at a height of 4 meters on a staircase, but it will probably be fine! All in all, a great device, which will really save me a lot of time.
