Abstract

An autonomous floor-cleaning robot comprising a housing infrastructure including a chassis, a power subsystem, a motive subsystem to propel the robot for cleaning operations, a command and control subsystem to control the 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 to sweep up particulates during cleaning operations, a vacuum assembly 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 robot includes a side brush assembly to entrain particulates outside the periphery of the housing infrastructure and to direct such particulates towards the self-adjusting cleaning head system.
