1. An autonomous cleaning robot comprising:
a drive system comprising wheels configured to move the autonomous cleaning robot in a forward drive direction about a floor surface;
a cleaning assembly arranged forward of the wheels of the drive system, the cleaning assembly configured to collect debris from the floor surface, the cleaning assembly comprising
a cleaning pad holder for holding a cleaning pad, and
a suction apparatus;
a dust sensor configured to detect an amount of debris accumulated on the cleaning pad; and
a controller configured to intermittently activate a vacuum function of the suction apparatus as the autonomous cleaning robot is moved in the forward drive direction during a cleaning run, wherein the intermittent activation is based on the amount of debris accumulated on the cleaning pad.
