A tubular tank cleaning tool for use in an R.V. waste storage tank or the like is provided with a rotating nozzle affixed to a tubular body for connection at its opposite end to a conventional garden hose. The improvement includes a flexible section of the tubular body having a coil spring within to allow the tool to be easily bent around corners and tight angles. The coil spring prevents the flexible section from kinking while a nozzle guard at the distal end of the tubular body prevents the nozzle from catching as the tool is inserted or withdrawn from a waste storage tank.
