DynaMop®'s traditional type microfibrer mop head, for spin mops, fans out to approx. 14"-15" in diameter. While this microfiber mop head it is super absorbent, because of the way the loops/braid in the strands are woven, dirt picked up by the strands tend to become trapped inside the loop and are not release back into the water. Some spin mop makers have devised an "agitator" inside the bottom of the spinning bucket to help remove the dirt from the microfiber strands, but these agitators have little effect. DynaMop® has resolved the issue by developing our own patented fluffy style microfiber mop head. This is just another one of DynaMop®'s advanced technologies in the spin mop world.
