Conjet ACR™ Robot


The Robot 327 is an electrically powered, track-driven, fully automated hydrodemolition concrete removal robot that is compatible with the Conjet ONE control system. The robot has been developed to work in confined spaces and areas. It passes through an opening less than 3 feet (0,9 meters) wide.

The Robot 327 is highly customizable. Different variations of tools and arms can be combined to match your project’s needs. Apart from the arm and tool configurations, the high-pressure lance on the Robot 327 can be equipped with either a single nozzle or a double nozzle assembly depending on the type of work. The robot can also be equipped with a winch for working in slopes. Further, a rotary head can be attached for surface preparation.

The Wireless Connection Kit establishes communication between the robot and the pump. The Wireless Communication Kit integrates the robot and the pump control systems. The pump operational data can be maneuvered and controlled from the robot to achieve one point of contact for the operator.


The Rotor Assembly R327 is a surface preparation tool that is designed for removal of the topmost layer of concrete and steel surfaces. The rotor is equipped with 2-4 nozzles for concrete removal and up to 20 nozzles for surface preparation.


The Feed Beam Extension R327 increases the width of the feed beam. This enables the cutting width of the robot to be increased.
