FlyLady's Big Mop Head (5.75 inches x 15.75 inches) comes with one Big Mop Cloth (8.66 inches x 15.75 inches) attached to it, which can be removed. Additional Big Mop Cloths are available to purchase, as well.

There are 2 spring loaded clamps on either side of the mop head (4 in total) that keep the Big Mop Cloth securely attached to the Big Mop Head. These clamps are easy to open and close, as well.

The Big Mop Cloth is nice and thick, which means you can wring it to the desired wetness and not have to run back and forth to keep rewetting it.

Laundering Instructions for Big Mop Cloth: Machine wash, warm or cold water - absolutely no fabric softener - or you can hand wash in warm or cold water. Hang or lay flat to air dry.
