Autonomous floor cleaning robot

Abstract

An autonomous floor-cleaning robot comprising a housing, a powered wheel drive, a command and control subsystem; and a cleaning head including a deck mounted to pivot with respect to the housing, a brush assembly mounted in the deck and powered to sweep, a vacuum assembly mounted in the deck separate from the brush assembly and behind the brush assembly in a cleaning direction of the robot and powered to ingest particulates during cleaning operations, and a deck adjusting assembly mounted in combination with the deck and the housing that provides lift to the deck, the lift balanced to respond to an increase in brush torque to lift the deck with respect to the housing or floor. The robot also includes a side brush assembly mounted with the housing to entrain particulates outside the periphery of the housing and to direct such particulates towards the cleaning head.
