Window cleaning in the 21st century

I'm really not the home of the year and I hate to wash windows but eventually it must be nunmal. But fortunately, there are now for all electronic means with which it (at least for me) is more fun and if in doubt go even faster. Absolute hardness test - The glass fronts seifenverkrusteten my shower. While Well, that's more of a challenge for the cleaner but I've tried to Leifheit anyway it.

And I must say I am pleasantly surprised. First I sprayed everything with window cleaner, then scrubbed with the supplied wiper something. So far so normal. The really interesting feature, namely the suction, works really well. The vacuum cleaner recognizes that one of the disc and is switched automatically. Then simply apply a little pressure drag over it and you're done. The discs see afterwards really streaks. Was it all a matter of not even 5 minutes for 3 discs.

Actually, it's just a logical evolution of the classic (and terrible) system. For me, definitely worth 5 stars.
