From Aquajet Systems AB, the Aqua Cutter 410V hydrodemolition robot uses 15,000- to 40,000-psi water jets to remove as much as 9 cubic feet per hour of concrete. Contractors can adjust the robot’s stroke to control the depth of cuts, and vary the water pressure depending on whether they are removing loose, deteriorated concrete from the sound below, or sound concrete to a predetermined depth. Operators can control the 410V from a distance using the unit’s radio remote control, either wireless or with a hard wire. It features a multi-axis 3D positioning system, ceramic nozzles, and the company’s Equal Distance System.
