A strength saving spiral mop pole has a gripping rod, an outer rod, an inner rod, a rotating module and a holding device. The outer rod is mounted in the gripping rod and has a receiving space and a spiral concave portion. The rotating module has a pressing block and a threaded block. The pressing block has a guiding rod. The threaded block is penetrated by the guiding rod and attached to the pressing block. The threaded block has multiple spiral protrusive parts engaged with the spiral concave portion. To use the spiral mop pole of the present invention, the outer rod is pressed and the threaded block is rotated in the outer rod. The pressing block and the inner rod are driven by the threaded block so that the spinning removal of water is achieved by the rotation.
