1. A roller for rotatable engagement with an autonomous coverage robot, the roller comprising:

  • a resilient flexible tube having inner and outer surfaces and defining a longitudinal axis;

    a hub disposed within the tube along the longitudinal axis;

    spokes extending between the inner surface of the tube and the hub, the spokes suspending the tube to float about the hub and transferring torque from the hub to the tube, a trace length of each spoke being longer than a radial distance between the hub and the inner surface of the tube, wherein the spokes are elastically deformable, collapsing from an undeformed shape toward the longitudinal axis to a deformed shaped and elastically rebounding back to the undeformed shape.
