Operating Guide

The circle spot function (Spiral Track™) is best for cleaning a small area with a large
amount of dirt or dust. It is a great way to target a newly soiled area, such as one
particular spill in an otherwise clean area. The zigzag spot function (Wae Track™)
is also useful for small spaces. It is very eective when mopping as its movement
pattern minimizes streaking on tile or hardwood oors.
13. My Bob is stopping and showing a Trouble Number on the screen.
How can I x this?
Bob’s Trouble Number noties you of the specic reason his work has been inter-
rupted. This intelligent, self-scanning feature allows you to identify the source of the
problem quickly. A Trouble Number rarely signals a defect and can be solved with
simple procedures. Along with words “Trouble Nr” there will also be a number on the
center of Bob’s screen (where Bob’s cleaning minutes can be seen). The numbers
range from 00 to 10. Each number represents an issue with a specic mechanical
part of Bob. To understand Bob’s language, consult the Trouble Numbers section
of the manual (page 42) for the cause of the problem as well as its solution.
14. What is the best way to clean Bob’s wheels?
To remove dirt and dust, use the cleaning tool or compressed air to clear the creas-
es of the wheels. For more ecient removal, put Bob in Check-Up mode (found in
the Self Check-Up section of this manual) and test the wheels. Clean the sides and
bottom of the wheels as they spin in order to achieve the most thorough clean.
15. My Bob just stopped while cleaning and the screen went off.
What do I do next?
Like other electronic devices with a CPU (computers, smart phones, etc.), Bob
might experience a momentary halt in his operating system. You can usually get Bob
back to work by simply turning the power button on his side OFF and ON again.
