Lateral reinstatement
& cutting protruding taps

Grinding, Milling and Cutting

Sewer Robotics reinstatement cutters feature precise movements and can be used with water driven cutter motors for extremely powerful and fast reinstatement or cutting intruding taps of any material. Designed durable and user-friendly, with maximum clearance and a wide scope of applications, easy to service, and easy deployment from tight manholes.

Powerful grinding, milling and cutting

Sewer Robotics offers rehabilitation robots in 3 different-sizes for optimized application ranges, maximized in-pipe clearances and easy deployment from tight manholes

These robots are all compatible with the same cable reels and control units and therefore easily exchanged. And if you only need a different size cutter occasionally, than we have loaner equipment available for you.

Cutter motor

Although most contractors appreciate the added power, low maintenance costs and easy upgrading to water jet cutting, there might be jobs where a water supply is not desired or silence more appreciated.

SEWER ROBOTICS cutters can be used with powerful water driven, pneumatic or silent electric cutter motors.

Compatible Configurations

Durable stainless body

Without delicate exterior parts and with a diameter of only 100mm (4”).

Its durable and short design provides ease of deployment from tight manholes and sufficient clearance to reach far inside pipes.

Adjustable speeds

Of the electric movements (driving and rotating) allow operators to drive to the job fast. Then reduce the speed to maximize precision.

Twist-and-lock mechanism

Convert the reinstatement cutter into a UHP Water jet cutting- or CCTV inspection robot within 60 seconds. The available, purpose-build, modules widen the robot’s application range, while UHP water jet cutting provides access to a niche market with high rates and low competition.

Great visibility

A wide-angle camera with continuously adjustable LED lighting is placed directly behind the cutter and easily cleaned with the on-demand lens cleaner.


The powerful WM300 water hydraulic cutter motor cuts rapidly through cast iron, concrete and CIPP liner material and leaves a smooth cut.

After removing the cutter motor, an (UV) spot repair packer can be attached via a “puck” coupling.

Hydro-pneumatic actuators

The 205mm (8”) ram lift and 90° cutter motor pivot provide a very wide application scope from 150 – 500mm (“6-20”) and are realized by hydro-pneumatic actuators.

These in-house developed, linear actuators are operated with compressed air and have an enclosed hydraulic circuit to combine the strength and precision of hydraulic cylinders with the convenience and serviceability of pneumatic actuators without hydraulics inside the robot.
