Butterfly sponge mop, also known as a PVA (polyvinyl alcohol) mop.
This type of mop is known for being super absorbent, picking up large amounts of liquid quickly.
It features a front-pull lever mechanism on the handle for hands-free, squeeze-action wringing of the sponge head.
The mop head is designed to closely fit the ground and is suitable for cleaning various surfaces like tiles, laminate, and parquet.
The sponge is often replaceable, allowing for easy maintenance and hygiene.
