About the Pure Water Power Hybrid Brush The dual trim design of the Pure Water Power Hybrid Brush incorporates bristles made from both nylon and boar's hair. The combination of these materials delivers a highly dependable water-fed brush you won't want to live without. The inner boar's hair bristles are shorter in length and work at efficiently agitating dirt and grime. The outer nylon bristles are longer and fan out, ensuring a smoother glide while also accessing window corners and edges with ease. With three sizes available, you can choose from a 16-inch, 20-inch, and 23-inch brush. The 16-inch and 20-inch brushes come equipped with four powerful pencil jets to provide a direct and steady stream of water onto the surface. They come with a XERO Push-to-Fit Double T-Fitting for seamless connection to your pole's hose. For larger windows, the 23-inch brush contains six pencil jets, a XERO Push-to-Fit Double T-Fitting, and two XERO Push-to-Fit T-Fittings. After you decide which size will suit your needs best, select the socket that will match your water-fed pole setup. Choose the Fast Lock option if your pole features the XERO Fast Lock attachment. The Fast Lock Swivel option offers the same convenience but allows for greater maneuverability with swift vertical and horizontal movements. For poles utilizing a Euro tip and a standard angle adapter, the Euro Thread option would be the best fit. *Please note that the brush sizes are relative to the splay of bristles and NOT the block size.
