QA & Troubleshooting

Common questions regarding fitment, capacity, and installation.

Why is my Roomba not charging or showing a red light?

This usually indicates a battery fault or connection issue. Try removing and reinstalling the battery for 15 minutes. Also, ensure charging contacts on both the robot and home base are clean.
My Roomba battery isn't lasting as long as it used to. What can I do?

Battery lifespan naturally decreases over time (typically 2-3 years). Ensure the robot is clean, especially brushes and caster wheel, as debris can make it work harder and drain the battery faster. Charging in direct sunlight or extreme temperatures can also affect performance. If it's old, a replacement is likely needed.
Can I use a third-party battery with my Roomba?

While iRobot recommends using authentic batteries to avoid voiding warranties and ensure optimal performance, high-quality third-party batteries, like Coredy's, are available. Be sure to choose a reputable brand with good reviews for compatibility and longevity.
What does "Charging Error 1" or "Charging Error 102" mean?

"Charging Error 1" means the Roomba can't detect the battery. "Charging Error 102" indicates a charge fault or potential liquid damage. For both, try reinstalling the battery and checking for damage. Ensure you're using an authentic or compatible battery.
