The Kärcher WV 75 plus is highly recommended and has convinced me completely! It delivers what it promises! After I received the Kärcher, I had this course immediately to try and I cleaned in just one hour 17 (!!!) windows inside and out. When brushing his window of house with a puller, the use of Kärcher's not a problem. One must, of course, a little on the "anatomy" of the equipment involved, but how many have already described, it really provides a streak-free result. The margins you have probably rework me a towel, but that is also in the nature of things. It is important, in fact, that one einfeuchtet the windows well and paying attention that not already dries during the suction of the water alone at the window, because then you get a streak-free result really. This applies not only for windows ... also mirrors, glass tables, tiles etc. can easily edit it. If you then also imagines that you can clean 17 windows in just one hour and with only a glass of water (250ml), then that's a very excellent thing! Very dirty window frames and sills you have to thoroughly clean the course beforehand by age method (bucket of water and a chamois leather). If the window frames but only slightly dirty, then this goes quite effortlessly with the included microfiber wiper. I have only washed out the microfiber cloth in between a couple of times, that's it. I am thrilled and can only highly recommend this product!
