1. Apparatus for cleaning a surface with a liquid jet, the apparatus comprising:
a primary fluid conduit having a longitudinal axis and two ends, a fluid-intake end and a fluid-exit end;
a first motor-driven drive assembly configured to engage the primary fluid conduit and turn the primary fluid conduit about the primary-fluid-conduit longitudinal axis;
a first motor configured to engage the first motor-driven drive assembly;
a section of the primary fluid conduit being inside of an adjacent penetration sleeve;
a section of the penetration sleeve being inside of a piston sleeve;
the piston sleeve configured to engage the penetration sleeve and move the penetration sleeve back and forth along a penetration-sleeve linear path over a primary-fluid-conduit exterior surface;
an actuator configured to engage the piston sleeve and move the piston sleeve back and forth along a piston-sleeve linear path;
a penetration-sleeve end being attached to an extension sleeve that has a first end and a second end;
the extension-sleeve second end being attached to a pull rod or a pull cable;
the pull rod or the pull cable being attached to a nozzle anchor and configured to pull on, push against, or release tension from the nozzle anchor as the penetration sleeve moves back and forth along the penetration-sleeve linear path;
the primary-fluid-conduit fluid-exit end being attached to a flexible conduit;
the flexible conduit being attached to a nozzle tip having the nozzle anchor thereon; and
a continuous fluid-flow channel that extends from the primary-fluid-conduit fluid-intake end through the flexible conduit.
