Autonomous floor-cleaning robot
First Claim
1. An autonomous floor-cleaning robot, comprising:
- at least two independently driven drive wheels, each of the independently driven drive wheels being independently moveable in a downward direction;
a brush assembly operable to sweep particulate debris from the floor surface as the autonomous floor-cleaning robot moves across the floor surface; and
a dual chambered dust cartridge comprising a first storage chamber for receiving macroscopic particulates swept through a first inlet into the cartridge by the brush assembly, a second storage chamber positioned rearward of the first storage chamber along a forward drive direction of the autonomous floor-cleaning robot, the second storage chamber for receiving microscopic particulates drawn through a second inlet by a vacuum assembly,a floor member that extends across both the first storage chamber and the second storage chamber, anda wall positioned between the first storage chamber and the second storage chamber,wherein the first and second storage chambers are configured to allow the microscopic particulates drawn by the vacuum assembly to enter the second storage chamber without passing through the first storage chamber.

Abstract
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.

15. A method of operating an autonomous floor-cleaning robot, the method comprising:
-
driving the autonomous floor-cleaning robot across a floor surface via actuation of a motor drive configured to independently drive at least two drive wheels, the at least two drive wheels biased toward the floor surface and independently moveable downwardly; sweeping debris comprising macroscopic particulates from the floor surface through a first inlet into a first storage chamber of a dual chambered dust cartridge by the brush assembly; and operating a vacuum assembly to generate an airflow to draw debris comprising microscopic particulates from the floor surface through a second inlet into a second storage chamber of the dual chambered dust cartridge, wherein the dual chambered dust cartridge comprises a floor member that extends across both the first storage chamber and the second storage chamber, a wall is positioined between the first storage chamber and the second storage chamber, and the first and second storage chambers are configured to allow the debris drawn by the vacuum assembly to enter the second storage chamber without passing through the first storage chamber. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
