A nozzle jet cleaning apparatus for unplugging drains includes an elongate hose having an outside diameter of 1/4 inch and having sufficient resistance to bending and kinking to permit the hose to be fed into a drain passage. A hose coupler is attached to one end of the hose to permit connection thereof with a household source of pressurized water. A cylindrical metal nozzle is mounted inside an end section of the hose at the other end and has a central axial passage extending to a single front aperture located at a front end of the nozzle. The axial passage is of uniform diameter and its front aperture is located at the end of the hose. During use of this cleaning apparatus, the hose is flexible and able to bend along substantially its entire length. An exemplary version of the hose is made of polyamide with polyester yarn reinforcement.
