A multifunction jetting machine (also known .as a combination jet-vac unit or multi-utility sewer machine) is an industrial system designed for high-pressure line scouring, heavy sludge vacuuming, pipeline de-siltation, and surface hydro-demolition. Instead of relying on single-purpose pumps, it integrates high-pressure water displacement with a high-CFM vacuum blower and recycling filtration on a single truck chassis or stationary skid.
