A sonic mop, alternatively referred to as a floor sweeper, was a machine created for the purpose of cleaning floors in a mechanical fashion. It was intended for operation by physically pushing it. The janitor of the Colossus platform, Opeepit, employed a floor sweeper for cleaning until it was seized by First Order forces who were occupying the platform, subsequently compelling him to clean the floor manually. On one occasion, Finn utilized one of these devices, leveraging the sonic energy it produced, to trip a First Order [officer].
