Cleaning robot roller processing

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 sweeper 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;
• multiple floor cleaning bristles extending radially outward from the core;
• 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.

A coverage robot comprising:

• a chassis;
• a drive system mounted on the chassis and configured to maneuver the robot;
• a controller carried by the chassis;
• a cleaning assembly carried by the chassis and comprising:
• a cleaning assembly housing;
• and
• at least one driven cleaning roller rotatably coupled to the cleaning assembly housing;
• and
• a roller cleaning tool carried by the chassis and comprising:
• a body configured to longitudinally traverse the roller;
• and
• protrusions extending outward from the body and configured to remove debris from the roller while passing over the cleaning roller.

A robot roller maintenance system comprising:

• a coverage robot comprising:
• a chassis;
• a drive system mounted on the chassis and configured to maneuver the robot;
• a controller carried by the chassis;
• a cleaning assembly carried by the chassis and comprising:
• a cleaning assembly housing;
• and
• at least one driven cleaning roller rotatably coupled to the cleaning assembly housing and comprising:
• a rotatable, 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 and configured to prevent errant filaments from spooling tightly about the core;
• and
• a filament stripping tool for the roller comprising:
• a substantially tubular housing defining first and second openings configured to receive the cleaning roller;
• and
• protrusions extending from an interior surface of the housing toward a central longitudinal axis defined by the housing to a depth that interferes with the compliant flap, the protrusion configured to remove accumulated filaments spooled about the roller passing through the housing.
