have me - because I needed a new window wiper - ordered the window sucker a few days ago.
Delivery by Amazon as always flawlessly and quickly.
Have the sucker then tried directly and unfortunately have to say that he is not quite as the thought of what he promised:
The vacuum cleaner has been tested several times in a 2-part window.
Result: It was almost impossible to clean the lower window.
Reason: hitting the windowsill. Man-stretched to the housing. Keep the suction oblique (or horizontal) did not work because it has almost completely lost then the suction force remained & extreme streaks and traces of water on the windscreen.
Since the lower disc is quite narrow, there was no way the cleaner to run horizontally. Headfirst also was not working.
While the upper window could be deducted, however, the vacuum cleaner did not receive all the water. Single small droplets remain - especially on the wheel rims.
The functionality to handle I then no longer tested.
Later, in direct sunlight, then came even more streaks on the window to light.
Ergo: Who does not wish to streak-free window, for which the device is perhaps what.
For me, however, it is useless and in my opinion, little more than a toy.
I'll conventionally nachputzen my window again and fall back on tried and tested in the future.
The device was therefore returned, the reimbursement by Amazon came as always quickly and easily.
