A cleaning system for equipment intended to be placed in a solid/liquid separation settler, the cleaning system including:

• a cleaning boom, defining an internal passage for the circulation of a cleaning fluid opening through at least one ejection orifice for cleaning fluid;
• a rotary drive shaft for rotating the cleaning boom, extending vertically between a lower end and an upper end, the drive shaft being rotatably mounted around a vertical axis of rotation, the cleaning boom protruding laterally relative to the axis of rotation, the drive shaft internally defining an internal cleaning fluid circulation channel fluidically connected to the internal passage of the cleaning boom;
• a rotation drive system of the drive shaft around the axis of rotation;
• wherein the internal cleaning fluid circulation channel is configured to be supplied with cleaning fluid through the lower end of the drive shaft.
