A mop is a tool generally used for cleaning floors.

A wet mop typically has a long handle and a head made of thick, soft strands of water-absorbing fabric. To clean a floor, the mop is soaked in a bucket of water or cleaning fluid and scrubbed against the surface. Some buckets include a wringer to strain excess water from the mop, so as not to saturate the floor. Mops are also often used to clean up liquid spills.

The inventor Jacob Howe received a patent for a mop in 1837. U.S. Patent 241
