Definitions

  • a cleaning roller mountable to a cleaning robot includes an elongate shaft extending from a first end portion to a second end portion along an axis of rotation.
  • the first and second end portions are mountable to the cleaning robot for rotating about the axis of rotation.
  • the cleaning roller further includes a core affixed around the shaft and having outer end portions positioned along the elongate shaft and proximate the first and second end portions.
  • the core tapers from proximate the first end portion of the shaft toward a center of the shaft and tapers from proximate the second end portion of the shaft toward the center of the shaft.
  • the cleaning roller further includes a sheath affixed to the core and extending beyond the outer end portions of the core.
  • the sheath includes a first half and a second half each tapering toward the center of the shaft.
  • the cleaning roller further includes collection wells defined by the outer end portions of the core and the sheath.
  • the center 114 of the cleaning roller 104a is positioned along the longitudinal axis 126a and corresponds to a midpoint of the length L1 of the cleaning roller 104a.
  • the center 114 in this regard, is positioned along the axis of rotation of the cleaning roller 104a.
  • the fixed portion 331a tends to deform relatively less than the free portions 331b, 331c when the sheath 302 of the roller 300 contacts objects, such as the floor surface 10 and debris on the floor surface 10.
  • the free portions 331b, 331c of the sheath 302 deflect in response to contact with the floor surface 10, while the fixed portions 331b, 331c are radially compressed.
  • the amount of radially compression of the fixed portions 331b, 331c is less than the amount of radial deflection of the free portions 331b, 331c because the fixed portions 331b, 331c include material that extends radially toward the shaft 306.
  • the material forming the fixed portions 331b, 331c contacts the shaft 306 and the core 304.
  • the first collection well 328 is positioned within the first half 322 of the sheath 302.
  • the first collection well 328 is, for example, defined by the first end portion 314 of the core 304, the elongate portion 305a of the support structure 303, the free portion 331b of the sheath 302, and the shaft 306.
  • the first end portion 314 of the core 304 and the free portion 331b of the sheath 302 define a length L5 of the first collection well 328.
  • the circles are concentric with one another and with the ring portions 412, 416.
  • an outer diameter of ribs 408, 410 closer to the center 326 is greater than an outer diameter of ribs 408, 410 farther from the center 326.
  • the outer diameters of the ribs 408, 410 decrease linearly from the first end portion 314 to the center 326, e.g., to the central plane 327.
  • the ribs 408, 410 form a continuous longitudinal rib 411 that extends along a length of the section 402a.
  • the rib extends radially outwardly from the longitudinal axis 312.
  • the height of the rib 411 relative to the longitudinal axis 312 decreases toward the center 327.
  • the height of the rib 411 for example, linearly decreases toward the center 327.
  • the outer surface of the shell 336 of the roller 300 and the outer surface of the shell 336 of the other roller defines a separation therebetween, e.g., the separation 108 described herein.
  • the rollers define an air gap therebetween, e.g., the air gap 109 described herein.
  • the separation increases in size toward the center 326 of the roller 300.
  • the frustoconical portions 341a, 341b by being tapered inward toward the center 326 of the roller 300, facilitate movement of filament debris picked up by the roller 300 toward the end portions 318, 320 of the sheath 302.
  • the width of the air gap corresponds to a minimum width between the roller 300 and the other roller, e.g., a distance between the outer circumference of the shell 336 of the roller 300 and the outer circumference of the shell of the other roller. If the vanes 342a, 342b of the roller and the vanes of the other roller are positioned such that the air gap is defined by the distance between the shells of the rollers, the width of the air gap corresponds to a maximum width between the rollers, e.g., between the free ends 502a, 502b of the vanes 342a, 342b of the roller 300 and the free ends of the vanes of the other roller.
