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.
