Brushes in this category are specific to WaterFed applications. WaterFed brushes come equipped with jets that spray pure water onto the glass as you brush. There are a few things to consider when purchasing a pure water system brush. The first is the weight of the brush because it's on the end of a potentially long pole and will increase the flex of the pole, as well as have an effect on your ability to hold the pole. The next characteristic to consider is shape of the brush, as it'll effect the way you clean the window. The last consideration should be about your preference of jet stream versus pencil stream, although some brushes comes with options for both.
