The idea is very good. An electric window cleaner cleans the play the discs in half the time. First the positives: Yes, it cleans the disk very quickly, however, he cleans unreliable (fly droppings and dirt stuck usually remains on the disk) and it produces streaks. I have this window cleaner shown a window cleaner who smiled wearily and said it was hinzubekommen with this device technically impossible streak-free window. Why, I asked? Now, the window cleaner leads the rubber lip of a stripper not in straight lines but in curved tracks, streaks can not arise so. When pulling straight arise at the edges of the rubber lip by excess water slight streaking edges. Actually, this excess water should be vacuumed, but it works poorly, so a clear defect in the device. I therefore recommend Vorwerk to quickly put the instrument from the market or to improve. No purchase recommendation!
