Drive Wheel Module issue
Customer observations
“Please inspect and clean Roomba’s wheel”
“Uh-Oh” + 1 beep (wheel drop error)
“Uh-Oh” + 5 beeps (drive stall error)
“Uh-Oh” + 7 beeps (wheel drop rate error)
Robot spins around in circles – circle dance
Roomba wiggles or rocks from side to side
Most common causes:
Roomba was started on an uneven surface or got stuck on an obstacle
during the cleaning cycle.
Troubleshooting:
•
Pick Roomba up and set back on ground
•
DRIVE WHEEL Module inspection and cleaning (Appendix C).
•
Replace drive wheel modules if fixes fail.
Circle Dance (Drive Wheel Module Problem)
Customer observations
Erratic spinning and arching
Extended circling around one wheel
Circling interspersed with wiggling or rocking behavior
Forward and/or backward circling
Circling at slow, normal or rapid speed
Most common causes:
Dirt has infiltrated the wheel encoder or a drive belt has failed.
Troubleshooting:
•
In MOST cases, the robot’s software will recognize and correct the
behavior within minutes.
If the battery was recently reset, the robot may
act erratic again at startup until the software has a chance to correct the
condition.
•
If the Robot does not resume normal driving behavior within the first
couple minutes of runtime, go to DRIVE WHEEL Module inspection and
cleaning (Appendix C). If cleaning wheel modules does not correct the
problem, both wheel modules may need to be replaced.
•
Replace drive wheel modules if fixes fail.
