Tried
"Number 5 does not give up" - that thing staring them really loudly vacuum producing at the plate while I (like an idiot behind the thing herwackelnd) holding the safety line, so that a good piece do not suddenly crashes. The thingy sucks onto a brush rotated in front of him and moves with the help of the other continued. Fascinating and funny somehow. And all with microfiber Wischelei. The unit operates slowly and run - the surface polishing - at the wheel along. We did not have the time and patience to test the cleaning effect (anyone who wishes to stand for several minutes in his hand next to the window with the Security Anti-crash-line?).
Somehow everyone's opinion oscillated between Amusement about the futility of this unit (in the time I would have the disk already "correctly" cleaned) and the perceived audacity to offer something on the open market:
In my "Test Management" possessed no windows on any opportunity to fix the anti-crash-leash. So you stay next to the miracle of technology available and holds the Schnürl. How stupid. Or home improvement creates an extra frame around the noisy window Imp. Yeah. And how is that part actually come in the corners?
We pack the expensive plastic pile back in the box.
Verdict
I can not find the slightest advantage of this device at best will. A good / bad list is unnecessary. In my opinion, the most distant Hobot polishing robot is a completely meaningless machine.
But I want to be fair. The part has crashed not once has anyone been injured and even destroyed no window. And we also laughed.
