Conjet ACR™ Robot

Hydrodemolition Robot 327

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.


  • Fully automated via the ConjetONE control system
  • Track extensions for maximum stability
  • Track sensors control travel distance
  • Arm and feed beam can turn 360°
  • Removable side covers enable maximum reach in corners
  • Compact feed beam
  • Accessory kit makes it very flexible and multi-purpose
  • Hydrodemolition applied

Know ONE – Know ALL

All Conjet ACR™ robots share the same control system – ConjetONE.

ConjetONE allows all operations to be configured from the remote radio control unit or
on the robot display, resulting in easy configuration, fast start-up time and high efficiency.

Powerpacks & Accessories for Robot 327

Powerpack 14

The endurance runners at particularly favourable operating costs.

Powerpack 20

Wireless Kit

The wireless kit is a signal receiver for the power pack and allows for wireless communication between robot and pump. Pressing any of the emergency stops on either the robot, control box or power pack shuts down all hydrodemolition equipment, including the high-pressure water.

Arm Extension

The arm extension is attached to the boom arm for work in tunnels with larger diameters or for giving the robot extended reach. When extended, the robot can reach up to 3 meters.

Base Extension

The base extension is used to adjust the center of rotation for the arm when working in tunnels or pipes. It can also be used to increase the reach of the robot in combination with the arm extension.


The rotors are suitable for cleaning applications or scarification of all surfaces. The rotor is normally equipped with 2-4 nozzles for concrete removal and up to 20 nozzles for surface preparation.

Fork Nozzle

The fork nozzle can replace the regular nozzle in the standard tool, providing a similar result to the rotor in terms of surface finish. It is mainly used for scarification.
