Hydro-jet cleaning is a method of cleaning with high pressure streams of water to remove build up and debris in drains and and sewer lines. This process is best described as a more powerful form of pressure washing.

Water blasters, or water jetters, are essentially pressure washers with extreme pressure from 1,000 PSI to 5,000 PSI. Their components include at least one water tank, an engine, a pump, a hose reel, a hose, and several nozzles. These units are classified generally as delivering ultra-high pressure. This range of pressures are designed for unique applications like pipe cleaning, water jetting, precision cutting, and surface preparation.
