You can buy new batteries here.
Roomba gets stuck on or avoids dark carpets and floors
Your Roomba does not like going over dark objects.
Cliff sensors problems
This is a common problem with many Roomba devices caused by a misperception in the device's cliff sensors. A Roomba’s cliff sensors are located on the bottom of the device and give it the ability to sense if it is going to fall off a ledge. However, these sensors often mistake a dark carpet or floor for a cliff. There is a fix for this!
Roomba is not picking up dirt or has empty bin
Your Roomba does not seem to be cleaning.
Bin needs cleaning
Check to see if your bin needs to be emptied. It is possible the Roomba's system does not sense that it is full.
Bin needs to be replaced
If your bin is all clean and is still not working, it may need to be replaced. The bin should easily slide out if you push on the large button above it. You can buy replacement bins here.

Sidebrush motor needs replacing
Check out our guide on how to replace your Roomba's sidebrush motor module.
You can buy a new motor module or motor here.
You can buy a new sidebrush here.
Sidebrush motor not rotating
Remove the Sidebrush motor, remove the screw holding the top of the motor module, unclip top of motor module and remove top. Check to see if metal pin through gear is in place, and remove from top. Check to see if brush mount rotates by gripping stem and rotate. If it does rotate move on to either replacing motor or whole motor module. If the stem does not rotate, then force stem though the hole (the stem is a single part with the gear seen inside) I had to use some considerable force so there is a chance it could break. after the stem/gear has been removed check for cracks and if so replace part. Clean any dirt in the hole of the motor module top. Lubricate the gear and also the top of the gear that rest between the motor module top, replace pin, place motor module top on to the body, rotate the stem to mesh the gears and push to clip top back into place, replace screw. Reinstall Sidebrush motor into Roomba.
