Title: Car wash water brush handle

Abstract: A car wash water brush handle includes a wobble tube and a piston tube. The wobble tube includes an entrance hose fitting, a reinforcing hose, a flexible boot and an exit hose fitting. The piston tube includes a tube body, a piston, a piston rod, a compression spring, an exit reinforcing hose and an exit hose fitting. When water flows through the tube body, the piston rod is forced into entrance hose fitting through pressure against the piston. The piston rod prevents the flexible portion of the flexible boot from being damaged during operation. The water flows through the tube body at a pressure of 90 psi. A brush head is threaded onto the exit hose fitting. A water hose is threaded into one end of a hand grip tube and the entrance hose fitting is threaded into the other end of the hand grip tube.
