Abstract
A cleaning roller mountable to a cleaning robot is featured. The cleaning roller includes an elongate member extending along a longitudinal axis of the cleaning roller, and a vane extending outward from the elongate member. The vane includes a first vane portion attached to the elongate member, and a second vane portion attached to the first vane portion. The first vane portion extends from the elongate member at a location intersecting a radial axis of the cleaning roller. The first vane portion extends along a first axis angled relative to the radial axis and away from the radial axis in a tangential direction. The second vane portion extends along a second axis angled relative to the first axis. A first angle between the first axis and the radial axis is greater than a second angle between the second axis and the radial axis.
