When Bob faces an uncomfortable situation, he will notify you by displaying TROUBLE NR., coupled with a two-digit number, on his screen. Each number corresponds to a certain issue Bob is having.
Trouble Number 00: Left Wheel
What to do:
- Start by checking the wheel for jamming. Use the cleaning tool or compressed air to remove any debris that may be jamming the wheel. If this does not solve the problem and Bob still displays Trouble Number 00, run a checkup test and see how the wheel performs.
Trouble Number 01: Right Wheel
What to do:
- Start by checking the wheel for jamming. Use the cleaning tool or compressed air to remove any debris that may be jamming the wheel. If this does not solve the problem and Bob still displays Trouble Number 01, run a checkup test and see how the wheel performs.
Trouble Number 02: Main Brush
What to do:
- Remove the main brush using a flat head screwdriver, and clean it thoroughly from end to end. You may use a pair of scissors to cut hair or thread wrapped around the brush, or a pair of tweezers to remove congestion from the notches where the main brush is held. If Bob displays Trouble Number 02 while cleaning on a shag carpet or rug, you may remove his main brush and allow him to vacuum without it.
Trouble Number 03: Front Wheel
What to do:
- Use the cleaning tool or compressed air to remove debris congesting the front wheel. If the congestion is not removable from the outside, detach the front wheel and remove the obstruction. If Bob’s front wheel is clean and spinning freely, his front wheel sensor may need to be replaced.
