A fluid dispensing system comprising: - at least one fluid source; - at least one pump (130-1, 130-2, 130-3,..., 130-N) configured to be supplied with fluid from the fluid source; - at least one telescopic fluid dispenser (140'-1', 140'-2', 140'-3',..., 140'-M') configured to receive fluid from the at least one pump (130-1, 130-2, 130-3,..., 130-N) and dispensing it towards at least one target object (150-1, 150-2, 150-3,..., 150-0), the at least one telescopic fluid dispenser (140'-1', 140'-2', 140'-3',..., 140'-M') being capable of extending from a rest position to an extended position and retracting from the extended position to the rest position; - at least one control unit configured to operate the at least one pump (130-1, 130-2, 130-3,..., 130-N) for supplying fluid according to a received command of washing at least one target object (150-1, 150-2, 150-3,..., 150-O); - a manifold having at least one inlet into which the fluid is gathered from the at least one pump (130-1, 130-2, 130-3,..., 130-N), and a number of outlets from which the fluid is distributed towards the target object (150-1, 150-2, 150-3,..., 150-0); and - at least one control valve assembly (V'-1, V'-2,..., V'-P') configured to be actuated by the control unit and arranged between the manifold and the at least one telescopic fluid dispenser (140'-1, 140'-2, 140'-3,..., 140'-M'), the at least one control valve assembly (V'-1, V'-2,..., V'-P') comprising a fluid inlet for receiving fluid from the at least one fluid source, and a first fluid outlet for discharging fluid into the at least one telescopic fluid dispenser (140'-1, 140'-2, 140'-3,..., 140'-M'); characterized in that the at least one control valve assembly (V'-1', V'-2',..., V'-P') further comprises a second fluid outlet for allowing fluid to flow back away from the at least one telescopic fluid dispenser (140'-1', 140'-2', 140'-3',..., 140'-M') when retracting from the extended position to the rest position. - at least one fluid source; - at least one pump (130-1, 130-2, 130-3,..., 130-N) configured to be supplied with fluid from the fluid source; - at least one telescopic fluid dispenser (140'-1', 140'-2', 140'-3',..., 140'-M') configured to receive fluid from the at least one pump (130-1, 130-2, 130-3,..., 130-N) and dispensing it towards at least one target object (150-1, 150-2, 150-3,..., 150-0), the at least one telescopic fluid dispenser (140'-1', 140'-2', 140'-3',..., 140'-M') being capable of extending from a rest position to an extended position and retracting from the extended position to the rest position; - at least one control unit configured to operate the at least one pump (130-1, 130-2, 130-3,..., 130-N) for supplying fluid according to a received command of washing at least one target object (150-1, 150-2, 150-3,..., 150-O); - a manifold having at least one inlet into which the fluid is gathered from the at least one pump (130-1, 130-2, 130-3,..., 130-N), and a number of outlets from which the fluid is distributed towards the target object (150-1, 150-2, 150-3,..., 150-0); and - at least one control valve assembly (V'-1, V'-2,..., V'-P') configured to be actuated by the control unit and arranged between the manifold and the at least one telescopic fluid dispenser (140'-1, 140'-2, 140'-3,..., 140'-M'), the at least one control valve assembly (V'-1, V'-2,..., V'-P') comprising a fluid inlet for receiving fluid from the at least one fluid source, and a first fluid outlet for discharging fluid into the at least one telescopic fluid dispenser (140'-1, 140'-2, 140'-3,..., 140'-M');
