Becky Duncan, on a Roomba, this is called the"Circle Dance" not the "Circle of Death" :-) Here are a couple of things you can try before you get a chance to tell us which specific model you have. DRIVE WHEEL Module inspection and cleaning
Check the wheels for obstructions.
Push the wheels up and down several times and shake out any loose debris that may be trapped in the wheel well.
Make sure the wheels turn freely.
If there is uneven resistance between the wheels, hold down Roomba’s SPOT and
DOCK buttons for 10 seconds to reset the robot and try again.
Check tires for wear and tear.
If tire treads are no longer visible, or if large tears are present, replace wheel modules.
If wheel module problems persist on flat surfaces when there are no obstacles present, replace wheel modules.
The other thing to consider is dirt/grime at the optical encoders that sense wheel motion. Take a look at those and clean those with some isopropyl alcohol. Last but not least, you can also check the drive motor on the module.

There are two wires, a Red and a Black one that connect to the motor.Find those two wires on the connector that plugs into the connector on the mainboard, apply power form a 9V battery to those wires, the motor should turn in one directiong. than reverse the wires, and the motor should turn into the opposite direction. If it does not, replace the motor, if it does you may have a bad component on the H Bridge. Hope this helps, good luck.

If it does not, replace the motor, if it does you may have a bad component, either a diode or a power transistor (pretty common) on the H Bridge. Hope this helps, good luck.
