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.
1. A floor cleaner comprising: a chassis; anda cleaning assembly carried by the chassis and comprising:a cleaning assembly housing; andat least one driven brush rotatably coupled to the cleaning assembly housing and comprising:an elongated core having an outer surface and end mounting features exten
1. A floor cleaner comprising: a chassis; anda cleaning assembly carried by the chassis and comprising:a cleaning assembly housing; andat least one driven brush rotatably coupled to the cleaning assembly housing and comprising:an elongated core having an outer surface and end mounting features extending beyond respective axial ends of the outer surface of the core and defining a central longitudinal axis of rotation;a compliant portion extending radially outward from the core to sweep a floor surface as the core is rotated about the central longitudinal axis of rotation; andan axial end guard mountable about one of the end mounting features, the axial end guard configured to prevent spooled filaments from traversing axially beyond the extremity of the mounting feature about which the axial end guard is mounted, wherein the end guard is removable from a longitudinal end of the core. 2. The floor cleaner of claim 1, wherein at least a portion of the axial end guard forms an interference fit with the end mounting feature about which the axial end guard is mounted. 3. The floor cleaner of claim 2, wherein the end guard comprises a flat torus and a mounting ring, the mounting ring extending in a direction away from a surface of the flat torus, and the mounting ring forming an interference fit with the end mounting feature about which the axial end guard is mounted. 4. The floor cleaner of claim 1, wherein the outward radial extension of the brush is greater than the outward radial extension of the axial end guard mounted on the end mounting feature. 5. The floor cleaner of claim 1, wherein the axial end guard defines a through hole through which extends the end mounting feature about which the axial end guard is mounted. 6. The floor cleaner of claim 1, further comprising a bearing circumscribed by the axial end guard, wherein the core is rotatable relative to the bearing. 7. The floor cleaner of claim 1, wherein the compliant portion further comprises multiple floor cleaning bristles extending radially outward from the core. 8. The floor cleaner of claim 7, wherein the bristles are disposed about the core in multiple rows, each row forming a substantially V-shaped groove configuration along the core. 9. The floor cleaner of claim 1, wherein the axial end guard forms a labyrinth seal about the end mounting feature on which the axial end guard is mounted. 10. A floor cleaner comprising: a chassis;a cleaning assembly carried by the chassis and comprising:a cleaning assembly housing; andat least one brush rotatably coupled to the cleaning assembly housing and comprising:an elongated core having an outer surface and end mounting features extending beyond respective axial ends of the outer surface of the core and defining a central longitudinal axis of rotation, the core rotatable relative to the cleaning assembly housing;a compliant portion extending radially outward from the core to sweep a floor surface as the core is rotated about the central longitudinal axis of rotation; andan axial end guard mountable in a fixed axial position relative to the core, the axial end guard configured to prevent spooled filaments from traversing axially beyond the extremity of at least one of the end mounting features, wherein the end guard is removable from a longitudinal end of the core. 11. The floor cleaner of claim 10, further comprising an end cap disposed at an axial end of the core, between the core and the mounted axial end guard. 12. The floor cleaner of claim 10, wherein at least a portion of the axial end guard is mountable in an interference fit with one of the end mounting features extending beyond respective axial ends of the outer surface of the core. 13. The floor cleaner of claim 12, wherein the end guard comprises a flat torus and a mounting ring, the mounting ring extending in a direction away from a surface of the flat torus, and the mounting ring forming an interference fit with the end mounting feature about which the axial end guard is mounted. 14. The floor cleaner of claim 10, wherein the axial end guard is mountable to circumscribe one of the end mounting features extending beyond respective axial ends of the outer surface of the core. 15. The floor cleaner of claim 10, wherein the compliant portion further comprises multiple floor cleaning bristles extending radially outward from the core.
