  • a chassis;

    a drive system mounted on the chassis and configured to maneuver the robot; and

    a cleaning assembly carried by the chassis and comprising;

    a cleaning assembly housing; and

    at least one driven flapper brush rotatably coupled to the cleaning assembly housing and comprising;

    an elongated core having an outer surface and end mounting features extending beyond axial ends of the outer surface and defining a central longitudinal axis of rotation;

    a compliant flap extending radially outward from the core to sweep a floor surface as the roller is driven to rotate, the flap configured to prevent errant filaments from spooling tightly about the core to aid subsequent removal of the filaments; and

    axial end guards mounted on the core adjacent the ends of the outer core surface and configured to prevent spooled filaments from traversing axially from the outer core surface onto the mounting features.
