A spraying arm for a cleaning machine for cleaning medical, pharmaceutical, and/or laboratory utensils is divided into two half-arms by a rotary coupling supplying spraying agent to and rotationally supporting the spraying arm around a vertical rotational axis. First outlet nozzles in the two half-arms are oriented to produce first spraying-liquid jets in such a way that, when looked at from one end of the spraying arm, all of the jets in the two half-arms are aimed in the same direction. Horizontally oriented second outlet nozzles are arranged at the free ends of the spraying half-arms in such a way that, when looked at from one end of the spraying arm, the second spraying-liquid jets emerging essentially horizontally from the two half-arms proceed in opposite directions for driving the spraying arm around the rotational axis of the rotary coupling.
