Etymology

Mid 17th century (in the sense 'mop for cleaning the decks'): back-formation from Middle English swabber (“sailor detailed to swab decks”), from Middle Dutch zwabber, from a Germanic base meaning 'splash' or 'sway', also found as nautical German Schwabber and Volga German Schwabber ("scrubber, mop, swab")
