THE PROBLEM
A manufacturing process error exists on a limited number of units involving the
front bumper wiring. This manufacturing error can sometimes result in a cliff
detection wire getting cut during normal operation.
DIAGNOSIS
There are two possible failure modes.
1. Roomba will not start cleaning. Instead, when a button is pressed, it flashes
all of the LEDs (the three buttons and the battery indicator) and emits a
series of 6 low tones.
2. Roomba starts up normally, but instead of starting its normal spiral, it backs
up a few inches while turning to the left. After doing this for a minute or so,
Roomba emits its “uh-oh” sound and stops. As usual for failures, Roomba
flashes whichever button was used to start it and emits the “uh-oh” sound
every 30 seconds or so.
Either of these symptoms may appear EVERY time Roomba is turned on and
started.
Confirmation may be obtained by asking the customer to look under the bumper in
the front and center. Two wires will be visible going from left to right. If either wire
is cut or broken, the unit is defective and must be exchanged. Note that it is
possible for the wires to look normal (outer colored insulation intact) but the wire
inside is broken.
THE SOLUTION
Return to store for exchange
