An autonomous floor-cleaning 
robot comprising a housing infrastructure including a 
chassis, a power subsystem; for providing the energy to power the autonomous floor-cleaning 
robot, a motive subsystem operative to propel the autonomous floor-cleaning 
robot for cleaning operations, a 
command and control subsystem operative to control the autonomous floor-cleaning robot to effect cleaning operations, and a self-adjusting cleaning head subsystem that includes a 
deck mounted in pivotal combination with the 
chassis, a 
brush assembly mounted in combination with the 
deck and powered by the motive subsystem to sweep up 
particulates during cleaning operations, a vacuum 
assembly disposed in combination with the 
deck and powered by the motive subsystem to ingest 
particulates during cleaning operations, and a deck adjusting subassembly mounted in combination with the motive subsystem for the 
brush assembly, the deck, and the 
chassis that is automatically operative in response to an increase in 
brush torque in said brush assembly to pivot the deck with respect to said chassis. The autonomous floor-cleaning robot also includes a side brush assembly mounted in combination with the chassis and powered by the motive subsystem to entrain 
particulates outside the periphery of the housing infrastructure and to direct such particulates towards the self-adjusting cleaning head subsystem.
