Cleaning rollers for cleaning robots

A cleaning robot comprising:

• a drive system to move the cleaning robot across a floor surface;
• and
• a cleaning roller mountable to the cleaning robot, the cleaning roller rotatable about a longitudinal axis of the cleaning roller in a first rotational direction, wherein the cleaning roller comprises
• an elongate member extending along the longitudinal axis of the cleaning roller;
• and
• a vane extending outward from the elongate member away from the longitudinal axis of the cleaning roller and extending longitudinally along an outer surface of the elongate member, the vane comprising
• a first portion attached to the elongate member, wherein the first portion of the vane is attached to the elongate member at a location intersecting a radial axis of the cleaning roller, the first portion of the vane extending along a first axis angled relative to the radial axis and away from the radial axis in a tangential direction, and
• a second portion attached to the first portion of the vane, wherein the second portion of the vane extends along a second axis angled relative to the first axis, a first angle between the first axis and the radial axis being greater than a second angle between the second axis and the radial axis.

A cleaning head for a vacuum cleaner, the cleaning head comprising:

• a conduit;
• and
• a cleaning roller configured to sweep debris into the conduit, the cleaning roller rotatable about a longitudinal axis of the cleaning roller in a first rotational direction, wherein the cleaning roller comprises
• an elongate member extending along the longitudinal axis of the cleaning roller;
• and
• a vane extending outward from the elongate member away from the longitudinal axis of the cleaning roller and extending longitudinally along an outer surface of the elongate member, the vane comprising
• a first portion attached to the elongate member, wherein the first portion of the vane is attached to the elongate member at a location intersecting a radial axis of the cleaning roller, the first portion of the vane extending along a first axis angled relative to the radial axis and away from the radial axis in a tangential direction, and
• a second portion attached to the first portion of the vane, wherein the second portion of the vane extends along a second axis angled relative to the first axis, a first angle between the first axis and the radial axis being greater than a second angle between the second axis and the radial axis.
