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.
