A twist mop comprises a pole, fibers connected to the pole, and a movable collar connected to both the fibers and the pole, so that the collar is movable in an axial and radial direction about the pole, where radial movement of the collar pulls taut the fibers. The mop comprises an upper spline is connected to the pole, a pawl connected to the collar, to allow the collar to move in a radial direction clockwise or counterclockwise about the upper spline. The collar has a radial step to engage the pawl. The pawl is shaped to flex toward the radial step both when the collar axially traverses the pole and when the collar twists in a first direction, around the upper spline. The pawl being shaped to bias towards the upper spline while the collar turns in a second direction, opposite to the first direction, around the upper spline.
