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.
