A rotary scrubber apparatus, the apparatus includes a tube member having a helical slot, an attachment end portion, a holding end portion, and an internal cavity extending therethrough. A biasing element is contained within the internal cavity of the tube member. A following pin extends through the helical slot. The following pin has an external portion that engages a handle, and an internal portion that engages the biasing element. A scrubbing element is coupled with the attachment end of the tube member and rotationally fixed therewith. When the handle is pressed towards the attachment end and the handle is prevented from rotating about the tube member, the tube member rotates to rotate the scrubber element. The apparatus thereby provides rotational movement of the scrubber to be generated from only linear movement of the handle provided by a user.
