  • Patent number: 9038233
    Abstract: A floor cleaning robot comprises a housing, wheels, and a motor driving the wheels to move the robot across a floor, a control module disposed within the housing and directing movement of the robot across the floor, a sensor for detecting and communicating obstacle information to the control module so that the control module can cause the robot to react to the obstacle, a removable bin disposed at least partially within the housing and receiving particulates, a first rotating member directing particulates toward the bin, and a second rotating member cooperating with the first rotating member to direct particulates toward the bin. The removable bin receives particulates directed thereto by the first and second rotating members and the particulates pass from the first rotating member to the removable bin without passing through a filter.

  • Patent number: 8763199
    Abstract: A robot includes a robot housing having a substantially arcuate forward portion and a motor drive housed by the robot housing and configured to maneuver the robot on a floor surface. At least two independently driven drive wheels are moveably attached to the robot housing and biased toward the floor surface, each of the drive wheels being moveable downwardly in response to the each of the drive wheels moving over a cliff in the floor surface. A plurality of cliff sensors are disposed adjacent a forward edge of the robot housing and spaced from each other, each cliff sensor including an emitter and a detector aimed toward the floor surface and configured to receive emitter emissions reflected off of the floor surface, each cliff sensor being responsive to a cliff in the floor surface and configured to send a signal when a cliff in the floor surface is detected.

  • Patent number: 8671507
    Abstract: A floor cleaning robot includes a housing having an underside, a substantially semi-circular front portion, and a substantially semi-circular rear portion. A displaceable bumper of a substantially semi-circular leading edge is located along a front portion of the housing. A leading wheel is mounted on the underside of the housing located adjacent to a mid-point of the semi-circular leading edge, and a battery pack cover is positioned rearwardly of the leading wheel and covers a battery pack that supplies power to the robot. At least two drive wheels are positioned rearwardly of the leading wheel, and at least one main brush is positioned rearwardly of the at least two drive wheels and is configured to rotate about an axis substantially parallel to the underside.

  • Patent number: 8656550
    Abstract: A floor-cleaning robot includes a wheeled housing having a perimeter, a motor drive operably connected to wheels of the housing to move the robot across a floor surface, and a bumper responsive to obstacles encountered by the robot. A controller is in electrical communication with both the bumper and the motor drive and is configured to control the motor drive to maneuver the robot to avoid detected obstacles across the floor surface during a floor-cleaning operation. A driven cleaning brush, rotatable about an axis substantially parallel to an underside of the housing, is disposed substantially across a central region of the underside and is positioned to brush the floor surface as the robot is moved across the floor surface. Additionally, a driven side brush extending beyond the perimeter is positioned to brush floor surface debris from beyond the perimeter toward a projected path of the driven cleaning brush.
