The drone remains attached to the hull thanks to the vacuum/aspiration force, removing any algae or typical vegetation that grows on the hull during long periods of rest in enclosed harbours. Check out our blog on why algae should be removed from the hullThanks to its rubber or PVA brushes on rotating tracks, the drone easily moves in all directions on any surface. The high-resolution underwater camera installed on the drone allows Keelcrab to be maneuvered via a remote control with cord connected to a tablet or phone. As for the cleaning aspect KeelCrab is equipped with central counter-rotating brushes with nylon bristles of varying length and size and easily interchangeable depending on purpose. The brushes are A.N.C.C.P. certified and do not remove anti-fouling paints. On the contrary, they make them last longer: numerous tests have shown that removing the first layer of vegetation (3/5 mm) on a regular basis significantly extends the efficiency of the anti-fouling agent; this prevents barnacles from attaching to the hull in the medium term.The drone also has a nylon filter bag for the recovery of waste material, algae or vegetation, resulting from the cleaning operation. The process of using KEELCRAB machinery allows for a clean, eco-friendly service without chemicals, keeping the hull protected whilst safeguarding water quality and marine life.
