Multi Pump Innovation (MPI), which makes net cleaning robots, will unveil a prototype of a new model at this week’s Aqua Nor trade show in Trondheim, the Norwegian company said today.

The “JetMaster” is faster and stronger than MPI’s previous models, such as the Racemaster, and is fully thruster-driven with rim thrusters. A rim thruster is a type of propeller that doesn’t require a central drive because the blades are mounted on a ring which constitutes the rotor of an electric motor.

MPI said the new washer would also have additional water jets and does away with the need for any belts to help it climb and adhere to the cage nets as it goes about its cleaning work.

“The JetMaster will also have the ability to wash from the outside of the nets and wash lice skirts and other structures outside the pen itself,” said MPI in a press release.

“As a result of its extra jets, the JetMaster also carries the ability to easily clean marine growth at the waterline (and above) line of the cage – an issue which can present problems for other products in this market.”
