Abstract: A cleaning apparatus for cleaning a drill string. The cleaning apparatus includes a base, an arm, a fluid flow conduit, and a motor. The base supports the arm on a drill floor of a drilling rig. The arm has a first end which is mounted on the base, a second end at which a spray nozzle is arranged, and at least one articulated joint via which the arm, or a portion of the arm, can pivot relative to the base. The fluid flow conduit is connected to the spray nozzle so that a pressurized fluid entering the fluid flow conduit can spray out of the spray nozzle. The motor pivots the arm about the at least one articulated joint so as to alter an orientation of the spray nozzle relative to the base.
