1. A floor-cleaning robot, comprising:

  • a housing structure including a chassis, a motive system operable to generate movement of the robot across a surface during floor-cleaning, a vacuum system disposed at least in part within the chassis and operable to ingest particulates and thereby provide floor-cleaning, a primary brush assembly operable to collect particulates from the surface during floor-cleaning. a side brush assembly operable to cooperate with the vacuum system or the primary brush assembly to direct particulates outside the periphery of the housing structure, which would be otherwise outside the range of the vacuum system or the primary brush assembly, toward the vacuum system during floor-cleaning, a removable dust cartridae operable to be removably integrated into the housing in communication with the vacuum system or the primary brush assembly, and operable to store particulates ingested by the vacuum system or collected by the primary brush assembly, a sensor system operable to generate signals representative of conditions encountered by the robot during floor-cleaning, and a control system, in communication with the motive system and responsive to signals generated by the sensor system to control movement of the robot, wherein the sensor system comprises a cliff detector operable to generate a cliff signal upon detection of a cliff, and the control system is responsive to the cliff signal to control movement of the robot upon detection of a cliff to enable the robot to escape from the cliff and to continue movement.
