A spray arm assembly and a washing appliance provided with same. The spray arm assembly comprises an upper spray arm and a lower spray arm, the upper spray arm being connected to the lower spray arm and being located above the lower spray arm; and further comprises a first ball assembly, and the first ball assembly is arranged at a position where the upper spray arm is connected to and cooperates with the lower spray arm; and the upper spray arm is rotatable relative to the lower spray arm. The hydrodynamic loss caused by using a connection method in a sliding friction manner in the prior art is reduced by means of the first ball assembly, and the smoothness during rotation of the upper and lower spray arms can be improved, and the noise can also be reduced.
