Conjet ACR™ Robot


The track-driven hydrodemolition concrete removal Robot 557 MPA XL is equipped with a multi-purpose arm allowing full flexibility. Together with an adjustable chassis, the robot is a versatile and compact solution with extended reach and stability.

Stability is key to secure full safety when operating an ACR™ robot. That is why the Robot 557 MPA XL has been designed with the ability to extend the tracks, as well as sliding the main body – both to shift the robot’s center of gravity.

An automatic Stability Control System is incorporated into all 557 MPA XL-robots. The SCS monitors the position of the feed beam and notifies the operator in case of a warning.

  • Up to 6,3 m vertical reach
  • Main body can slide back up to 400 mm for increased stability
  • Tool-kits available ensures multi­purpose use
  • Diesel or electric power

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.


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.
