Ok, first mistake was perhaps that I tried the window cleaner equal to these high overhead windows. They looked after from worse than before. So once practice on normal windows, I thought.
I made it as my Kärcher also and was disappointed. Typically water with some shampoo - do not laugh, a valuable tip a cleaning lady in our company has been to get a streak-free window. It really works. So clean windows so, then sucker on and off you go.
I noticed that the Leifheit works much of difficult. While I do not have to think about the Kärcher, I feel you have to stay at the Leifheit in a specific, relatively narrow angle of inclination of the window, otherwise it does not suck the water off or sucked weaker.
Even the bottom of the window, because you have to do then wipe the water by hand from the frame. The Kärcher I come down on the window, then leave quickly with the lip movement to expire on the window frame, finished. Maybe that has something to do with the fact that you get just the water really well vacuumed only in certain tendency to Sauggrund at Leifheit.
For me, even ugly, because just time-consuming, if I only clean the window and then immediately go to the sucker over, there are streaks. I have to rinse with clean water, then it goes. The Kärcher pulls right the dirty water everything from streaking. The rubber lip also feels different.
Positive is the simple attachment of the stem at Leifheit. So you could wish for usability.
Conclusion:
When overhead cleaning I have to still hammer out a satisfactory result. It may be, if you look long and busy handling then out that you can work well with the device. But if I have to make only a window Diploma ;-) for the device, as it seems to me at Leifheit, then I would even prefer the pure hand cleansing.
During normal window cleaning I have the comparison and because it was easy to unpack the Kärcher time to get going, no problem. Even with windows with something more unusual forms or narrow places where you then have to take the cleaner once in the left hand or needs to perform a circle, not a problem. When Leifheit I get up today with my weaker left hand, because the tendency of the device to the glass then is probably different from anything out. The circular window I do not get streak-free, since it looks always the radius without rework.
We will probably have to buy us the stem extension for Kärcher and hope that one then the high window without a ladder-climbing gets clean.
The Leifheit we now use after the notice of an evaluator for the tiles in the shower. In the calcareous water here is a wonderful solution, and thus the money was not completely thrown out. Only a window sucker he is not useful for my idea of Handy.
