Brush for autonomous cleaning robot
First Claim
1. An autonomous cleaning robot comprising:
- a drive configured to move the robot across a floor surface;
a side brush proximate a lateral side of the robot; and
a motor configured to rotate the side brush about an axis of rotation,wherein the side brush comprisesa hub configured to engage the motor of the robot,a plurality of arms each extending outwardly from the hub away from the axis of rotation and each being angled relative to a plane normal to the axis of rotation of the side brush, each of the arms comprising a first portion extending outwardly from the hub away from the axis of rotation and a second portion extending outwardly from the first portion away from the axis of rotation, an angle between the first portion of each of the arms and the plane being larger than an angle between the second portion of the each of the arms and the plane, wherein the second portion of each of the arms is angled relative to the first portion of each of the arms in a direction opposite a direction of rotation of the side brush, anda plurality of bristle bundles, each of the bristle bundles attached to a respective one of the plurality of arms and extending outwardly from the second portion of the respective one of the plurality of arms.

Abstract
An autonomous cleaning robot includes a drive configured to move the robot across a floor surface, a brush proximate a lateral side of the robot, and a motor configured to rotate the brush about an axis of rotation. The brush includes a hub configured to engage the motor of the robot and arms each extending outwardly from the hub away from the axis of rotation and each being angled relative to a plane normal to the axis of rotation of the brush. Each of the arms include a first portion extending outwardly from the hub away from the axis of rotation and a second portion extending outwardly from the first portion away from the axis of rotation. An angle between the first portion of each of the arms and the plane is larger than an angle between the second portion of the each of the arms and the plane.
