A friend raved to me about their latest achievement, the Kärcher WV75 window sucker. Since I now could no longer be delayed longer my window cleaning action, I relied on the testimony of friends and the many positive reviews about this device from Amazon, and have ordered! What can I say: enthusiasm across the board !! After having dealt with all the individual parts and assembled the window sucker, you can get started very quickly. So easy I would have hardly imagined - I'm going to probably passionate window washer. That the right and left and at the edges of each always remains below a little water, I think now is not so dramatic. This is easy to wipe with a cloth - without streaks. Incidentally, the window sucker works more than fine when the sun shines through the window. In conventional cleaning with chamois leather or cloth and glass cleaner there was ALWAYS streaks. The Kärcher is no problem at all!
