Abstract: The present invention relates to a device for cleaning and polishing connections of underwater equipment, comprising: a connection element (3) adapted to be connected to a torque-generating device; a cleaning-fluid-discharge device (2) comprising at least one cleaning-fluid reservoir (20); and a cleaning element connected to the discharge device via a support (4) for the cleaning element, wherein the support (4) for the cleaning element comprises at least one channel (41) that in a fluidic manner connects the at least one cleaning-fluid reservoir (20) to the cleaning element. In addition, the device comprises a control system (1) for dispersal of cleaning fluid, comprising a telescopic shaft (1) that comprises a fixed part (11) and a movable part (12), which are adapted to move longitudinally relative to one another, wherein: the movable part (12) extends at least partially inside the fixed part (11); the fixed part (11) is secured to the fluid-discharge device (2); and the movable part (12) is secured to the cleaning element (42); a compressible damping element (10) is provided between the fixed part and the movable part (12); an upper portion of the movable part (12) extends partially inside the fluid-discharge device (2), via an opening (21) in the fluid-discharge device (2); and the channel (41) that fluidly connects the at least one cleaning-fluid reservoir (20) to the cleaning element (42) extends longitudinally through the movable part (12) and extends partially through the upper portion of the movable part (12).
