12. When should I use different cleaning modes?
Robot mode is Bob’s default mode and gives him enough time to
thoroughly cover a large area. If you would like to clean a smaller area, you may
use Quick Clean mode, which lasts 30 minutes, or Touch Up mode, which lasts
15 minutes.
Waffle Track
™
and Spiral Track
™
are best used when cleaning a small spill. When
Waffle Track
™
is selected, Bob travels in a grid pattern; when Spiral Track
™
is
selected, Bob travels in a gradually widening circle. Select Wall Track
™
to make
Bob travel along the perimeter of your room.
13. Bob is stopping and displaying TROUBLE NR. on his screen. How can I fix this?
Bob’s Trouble Number let's you know the specific reason his work has been
interrupted. This allows you to identify the source of the problem quickly.
A Trouble Number rarely signals a defect, and usually has a simple solution.
Along with words TROUBLE NR., there will also be a two-digit number in the cen-
ter of Bob’s screen. The numbers range from 00 to 10. Each number represents
an issue with a specific part on Bob. Refer to the Troubleshooting section of this
manual ( page 65 ) for the cause of the problem as well as the solution.
14. What is the best way to clean Bob’s wheels?
Use the cleaning tool or compressed air to clear the creases of the wheels. For
a more thorough clean, wipe the sides and bottoms of the wheels as they spin
during checkup mode ( see page 77 ).
