Autonomous floor cleaning robot

摘要

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.

主权项

1. An autonomous floor-cleaning robot comprising:
a housing infrastructure including a chassis having forward and rearward ends; a single removable collection cartridge carried by the chassis; a motive subsystem drive assembly operative to propel the autonomous floor-cleaning robot forward for cleaning operations; a control module operative to control the autonomous floor-cleaning robot to effect cleaning operations; a brush assembly powered by the motive subsystem to that sweeps up particulates during cleaning operations; a vacuum assembly powered by the motive subsystem that collects particulates during cleaning operations, the vacuum assembly including a vacuum inlet rearward of the brush assembly, the vacuum inlet including a first compliant blade having a generally rectangular configuration and a lateral dimension that defines a predetermined width of the vacuum inlet, wherein the first compliant blade extends beyond a lateral dimension of the brush assembly and is positioned to graze a surface to be cleaned; and a replaceable filter retained in a chamber of the cartridge; wherein both the brush assembly sweeps and the vacuum inlet collects particles into the single removable cartridge; wherein the collection cartridge comprises a curved arcuate sidewall substantially continuing with an external sidewall of the housing infrastructure, the housing infrastructure having a structural envelope defining a generally cylindrical shape generally symmetrical along a forward portion of the housing infrastructure.
