Aquajet offers the Ergo System. The robot offers four times the power of a hand lance in a compact footprint that contractors can easily move around the job site. It is ideal for work on floors, walls and ceilings. The Ergo System incorporates: the controller unit, which powers and controls the hydraulics, the Ergo Power Head, which manipulates the high pressure lance, and either the spine or the climber, unique systems used to support and maneuver the power head, based on project needs.
