To put Bob in checkup mode:

1. Flip Bob's power switch OFF and place him on a light-colored surface.

2. While holding down the CLEANING MODE button on Bob’s cover, flip Bob’s power switch ON.

3. Bob will chirp three times to let you know he is now in checkup mode. The screen will show a word or a number sign. You may release the CLEANING MODE button. Do not press any additional buttons.

Step 1: Edge Sensors

- You should see AUTO, TIME, SPOT, and UV lit on Bob’s screen.
- If all four lights do not turn on, flip Bob over and wipe his edge sensors with a clean cloth. See if all four lights turn on now.
- Lift Bob about 6 inches (15 cm) off the ground. You should see the four lights turn off.
- Place Bob back on the floor and move on to the next step without pressing any additional buttons.


Step 2: Wall Sensors

- Use a thick, flat, and white surface to imitate a wall in front of Bob. Drag the imitation wall from the left side of Bob's bumper around to the right side.
- The first battery bar, second battery bar, third battery bar, DIRTY, and ERROR should light up one-by-one as you do this.


Step 3: Charging Station

- Press Bob’s CLEANING MODE button once.
- Place Bob about 5 inches (18 cm) away from his charging station with the middle of his bumper directly facing the sensor on top of his station. Bob’s screen should display the number 77.
- If you see a different number, make sure that Bob’s bumper is perfectly aligned with the sensor on top of his station. If Bob still does not display 77, clean the window on the charging station and the small hole in the center of Bob's bumper.
- Do not press any additional buttons.


Step 4: Touch Sensors

- Press the CLEANING MODE button on Bob’s cover once. Bob’s screen will go blank.
- Press the left side of Bob’s bumper and the battery bars should light up on his screen; release the left side and the bars should disappear.
- Next, press the right side and ERROR should light up; release the right side and ERROR should disappear.
- Press the center of the bumper and both the battery bars and ERROR should light up at the same time.


Step 5: Display Screen

- Press the CLEANING MODE button one more time. Each icon on the screen should light up in a repeating rotation.


Step 6: Brush and Vacuum Suction

- Press the CLEANING MODE button again. Now press the CLEANING PROGRAM button.
- The main and side brushes should spin, and air should flow out of the back of the dustbin.
- If you do not feel air flowing out of the dustbin, then Bob’s vacuum motor may need to be replaced.
- If the brushes are not moving, remove and clean them before repeating the test.

Step 7: UV Light and Wheels

- Lift Bob off the floor or place him on his side to keep him from running away!
- Next, press the MODE button and his wheels should drive forward.
- Flip Bob over and you should see his UV lamp lit. Do not look directly into the UV lamp.
- Press the MODE button once more. Bob’s wheels should drive backwards and his UV lamp should turn off.

If Bob completes the checkup test without any issues, then his internal parts are working properly!
