Sponge mop heads are constructed with a cellulosic, rubber, or plastic foam block, usually attached by crimping a metal clip on one side. Sometimes, the foam mop head may be covered by a cloth or mesh sheet, to improve its resistance to wear from heavy scrubbing.

The sponge is then attached to a handle mechanism which can compress the mop head, by means of rollers or a pivoted flat perforated blade. For consumer-grade sponge mops, the mop mechanism may be made of either plastic or metal. For heavy-duty or professional use, the mechanism is usually made of a corrosion-resistant metal such as [[stainless steel]], and the mop head is often rubber or premium plastic foam.

For [[clean room]] environments, a stainless steel handle and mechanism are preferred, along with a mop head made of a foam which has been formulated to minimize shedding of small particles. For use in microbiological labs, mops are made of materials which can be sterilized by [[autoclave]] or by [[ethylene oxide]] treatment.<ref>{{cite web |title=Roll-O-Matic CE "Clean" Sponge Refill with Microfiber Lamination |url=https://ce.vileda-professional.com/CE-Roll-O-Matic/Roll-O-Matic®-CE-“Clean”-Sponge-Refill-with-Microfiber-Lamination/p/Roll-O-Matic_CE_Clean_Sponge_Refill |website=Vileda Professional |publisher=FHCS GmbH |access-date=2022-03-14}}</ref>
