  • Patent number: 11154176
    Abstract: A mop (100) includes a mop head (101) having a housing (302) defining a major surface to couple to a cleaning pad (204). One or more flappers (201,202) are disposed along the major surface. The flappers, in response to actuation of an actuator (104), selectively pivot from a closed position disposed within the housing and substantially parallel with the major surface to an angularly displaced open position extending distally outward from the major surface. A user actuates the actuator (104) to detach the cleaning pad from the major surface without having to handle the cleaning pad.
