The invention relates to a device for guiding a cable (110, 120) for linking a submerged robot, in particular a robot for cleaning swimming pools, to the device for controlling and powering same, said guiding device comprising: a. a coupling including a rotary connector (141, 142), connected by one side to a first floating portion (110) of the linking cable extending from the control and power device to said coupling and, by the other side, to a second portion (120) of the linking cable extending from said coupling to the submerged robot; b. a floating mounting (100) including: bi. a float (130); bii. an interface (143, 243) for mechanically linking the rotary connector to said float; and biii. a hood (135, 335) extending above the surface when the floating mounting is submerged in a liquid and removably connected to the float; c. in which the mechanical link between the float and the rotary coupling is a ball-and-socket link.
