In addition to being used to make pipe connections, this precision system removes and cuts away scale such as roots, illegal connections, protrusions, solidified obstructions, and mills cracks to ensure a suitable surface for bonding repair materials such as CIPP.

It consists of a remotely controlled, self-propelled robot with an integrated milling head that incorporates a video camera connected to the control unit, allowing the work to be viewed on a screen as it is being performed.
