Cleaning robot roller processing
First Claim
1. A coverage robot comprising:
- 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, wherein the end guard is removable from each longitudinal end of the core.

Abstract
A coverage robot includes a chassis, a drive system, and a cleaning assembly. The cleaning assembly includes a housing and at least one driven cleaning roller including an elongated core with end mounting features defining a central longitudinal axis of rotation, multiple floor cleaning bristles extending radially outward from the core, and at least one compliant flap extending radially outward from the core to sweep a floor surface. The flap is configured to prevent errant filaments from spooling tightly about the core to aid subsequent removal of the filaments. In another aspect, a coverage robot includes a chassis, a drive system, a controller, and a cleaning assembly. The cleaning assembly includes a housing and at least one driven cleaning roller. The coverage robot includes a roller cleaning tool carried by the chassis and configured to longitudinally traverse the roller to remove accumulated debris from the cleaning roller.
