Apparatus for cleaning a surface with a liquid jet, the apparatus having: 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 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 swivel rod that has a first end and a second end; the primary-fluid-conduit fluid-exit end being attached to a fixed nozzle having a first end and a second end; the fixed-nozzle second end being attached to a swivel nozzle; the swivel-rod second end being attached to the swivel nozzle; the swivel nozzle configured to pivot between a fully extended position and a fully retracted position as the swivel rod respectively extends and retracts as the penetration sleeve moves back and forth; and a continuous fluid-flow channel that extends from the primary-fluid-conduit fluid-intake end through the swivel nozzle.

An angled cleanout connector for a recreational vehicle is provided with an aperture for insertion of a pressure hose with a jetter head into the wastewater outlet pipe of the RV. The pressure hose slidably passes through a boot in the connector aperture and may be inserted through the wastewater piping and into the black-water tank. Standard residential or campsite water pressure will propel narrow, high-pressure streams through the jetter tube to clean the pipe.

A pipe cleaning apparatus can be used to clean and service an interior surface of a pipe. The apparatus has cleaning nozzle that spray the interior surface of the pipe as they rotate around a central axis. Drive wheels allow the apparatus to traverse the pipe in a longitudinal direction. Further, guide wheels keep the apparatus positioned within the pipe. Adjustable mechanisms allow the wheels to adapt to different size pipes. A drive shaft, air motor, and worm gears coordinate the movement of the apparatus to the speed of the cleaning nozzles, which varies depending on the diameter of the pipe.

Pipe inspection systems including a push-cable, jetter, and camera assembly are disclosed. A jetter nozzle may be configured to spin and/or propel the camera head within a pipe or other cavity. A cutter line may be attached to the camera head to clean obstructions. A sonde may be coupled to a camera head to generate magnetic field signals for use with a buried utility locator to locate a pipe or other cavity into which the camera head is deployed.

Electrical interference signals are to be eliminated during operation and video quality improved in a metal extension sleeve incorporated in an internal space of a nozzle element of a pipe cleaning nozzle and/or inspection nozzle for contacting an electrical conductor via a camera adapter through the internal space of the nozzle element with a camera module fastened outside the nozzle element. The extension sleeve spans the length of the nozzle element and is releasably fastened form-fit and/or force-fit on the camera adapter and the at least one extension sleeve has coupling threads along the outer surface of the coupling section, with which the extension sleeve is tightened in the internal space of the nozzle element. The metal extension sleeve has an electrical insulation layer made of plastic on its outer surface spaced from the central longitudinal axis, which is applied fully to the entire outer surface without defects.

A device for cleaning the internal surface of a pipe has a main pipe axis. The device further includes one or more generally tubular conduits, including a conduit wall, at least one of the or each tubular conduit including an inlet to receive pressurised gas into the tubular conduit. One or more nozzles is deployed around the outside of the or each tubular conduit, with the or each nozzle being in fluid connection with the tubular conduit. At least one nozzle is directed at least partially to direct fluid in a direction non-perpendicular to the main tubular conduit axis, with one or more spacer elements to hold the or each tubular conduit in spaced relationship to a pipe.

A nozzle is provided for cleaning the interior of pipes that is capable of cutting through obstructions disposed in the interior of pipes. The nozzle comprises a three-dimensional (3-D) fluid mechanics comprising a 3-D redirection configuration that redirects high-pressure fluid received in the nozzle from a fluid source onto multiple pathways, or channels, toward rearwardly-facing jet outlets. The 3-D fluid redirection configuration redirects the water in a manner that reduces or eliminates vibrations in the nozzle that can degrade performance and cause other problems.

A method and system having nozzle for cleaning the interior of a pipe is provided. The nozzle has a rinsing fluid inlet and a plurality of rinsing fluid discharges, wherein each of the rinsing fluid discharges is arranged for discharging fluid substantially in a rearward direction. The nozzle has a plurality of rinsing fluid outlets for discharging rinsing fluid substantially in the rearward direction. Each of the rinsing fluid outlets is enclosed by a tube forming a passage between the tube and the rinsing fluid outlet. Each tube is connected to a material suction inlet and comprises a tube outlet for discharging a mixture of material and rinsing fluid.
