US 12,178,384 B2 · Brush for autonomous cleaning robot

Abstract

An autonomous cleaning robot includes a drive system to move the autonomous cleaning robot about a floor surface, a cleaning head on a bottom portion of the autonomous cleaning robot, a side brush on the bottom portion of the autonomous cleaning robot, and a vacuum system in pneumatic communication with the opening. The cleaning head is configured to direct debris from the floor surface into the autonomous cleaning robot as the autonomous cleaning robot moves about the floor surface. The side brush is rotatable about a rotational axis forming a non-zero angle with a floor surface, and the side brush comprising an opening.
