Hose mooring fluid jet propulsion system

The application provides a hose tethered fluid jet propulsion system. According to the fluid jet propulsion system, a local device is used for providing to-be-distributed fluid for a fluid jet propeller, a mooring hose is used for transferring the to-be-distributed fluid, the fluid jet propeller comprises at least one fluid jet unit and a supporting device, and the fluid jet unit comprises a connecting pipe and a nozzle which are sequentially connected and is used for jetting out the jet fluid; and the controller is connected with the fluid jet unit to enable the fluid jet propeller to fly under the combined action of thrust provided by all jet fluids, and the controller adjusts the jet quantity of the jet fluids of the fluid jet unit according to the real-time flight attitude of the fluid jet propeller so as to control the flight path of the fluid jet propeller. The fluid jet propeller in the system can automatically fly and jet fluid, so that sanitation workers do not need to pay much physical labor when ir
