Edge Sensors

Bob's edge sensors are dirty, or confused by dark-colored floors.

What to do:

  1. Wipe the sensors clean with a dry cloth, or use compressed air. Bob's 4 oval-shaped edge sensors are located on his bottom, near his bumper.
  2. If Bob displays this message while working on dark­-colored floors, then you will need to deactivate the edge sensors. To do so:
    1. Hold down the CHECKUP button on Bob. The 4 bars above "Check Up" will begin to flash.
    2. Release the CHECKUP button after the bars remain still.

    Touch Sensors

    There is a small piece of debris trapped underneath Bob's bumper.

    What to do:

    1. Gently tap on Bob's bumper to release the object, or use compressed air to clear the space of debris.
    2. Press the corner ends of the bumper until you hear a “click." If the bumper is not clicking on its ends, then the touch sensors may need to be replaced.

    Left/Right Wheel

    The left or right wheel is jammed.

    What to do:

    1. Use the cleaning tool or compressed air to remove debris from the wheel.
    2. If this doesn't resolve the issue, then Bob may need a new wheel.

    Main Brush

    Bob is having difficulty moving his main brush.

    What to do:

    1. Clean Bob's main brush:
      1. Remove the main brush using a flat head screwdriver.
      2. Clean the brush thoroughly from end to end. You may use a pair of scissors to cut hair wrapped around the brush, or a pair of tweezers to remove congestion from the square metal indentation where the main brush is held.
      3. If Bob has trouble cleaning on a shag carpet or rug, you may remove his main brush and see how he performs without it.

      Obstacle Sensors

      The wall sensors are blocked or dirty.

      What to do:

      1. Wipe the translucent strip on Bob's bumper with a damp cloth or remove to clean underneath it.
      2. To ensure nothing is jammed underneath the bumper, gently tap it or use compressed air to clear it of debris.


      The dustbin is not installed properly, or the dustbin's metal contact points are dirty.

      What to do:

      1. Remove Bob's dustbin and empty it. Turn the dustbin around and gently wipe the two metal connectors on its bottom.
      2. Replace the dustbin and make sure it connects properly.


      Bob is having trouble with his central computer.

      What to do:

      1. Contact our support team, as Bob needs to come into the bObsweep hospital for a checkup.

      Power System

      Bob's battery has absolutely no juice left or has loose connection. 

      What to do:

      1. Open up Bob's battery compartment and check his battery connection.
      2. If the connection appears fine, then charge Bob on his station
      3. If this fails to resolve the issue, then charge Bob with his charging adapter.
      4. If Bob is able to charge with the adapter, then he needs a new charging station. If connecting the adapter fails to wake him, then he likely needs a new charging adapter.
