Abstract
A rotating hose device for rotating and helically thrusting a high pressure hose and biased nozzle into a pipe for the purpose of cleaning the interior surface of the pipe. The rotating hose device is powered by converting linear torque from a rotating high pressure hose into linear thrust, forcing the high pressure hose and biased nozzle into the pipe, where the high pressure hose and biased nozzle travel through the pipe in a helical manner. The present invention more effeciently cleans conduit, pipe and other tubular members, by constantly positioning the biased nozzle against the interior surface of the pipe and avoiding the 'streaking' effect left by prior art nozzles. The helical pitch of the rotating high pressure hose, speed and direction of travel of the high pressure hose are controlled through the alignment of the drive wheels in the rotary hose drive.
