Whenever I saw a professional cleaner at work I wish also to have such a puller. And now I have added to it and am very happy with it. If the windows are heavily soiled, a damp sponge is sufficient with a splash Pril for wetting the disc as a pretreatment. Then pull in slightly overlapping tracks - done! You can also - like the pros - pull in serpentine lines, then must however be careful not to overlook any area. And if it has been raining heavily and the drops on the window "available", just briefly about it go with the puller and the disc looks like freshly cleaned. I had imagined! Simple, little expensive and effective !!
