Unplug Home Base. Clean the two metal charging strips with dry cloth. Look for debris or corrosion. These must be shiny and clean.
Reset Roomba
Hold the Clean button for 20 seconds until light ring shows swirl. Release and wait for reboot. This clears software glitches causing Error 2.
Try Different Outlet
Move Home Base to different outlet. Some power fluctuations can cause charging errors. Use outlet not on dimmer or surge protector.

Quick Solutions
Still having issues? This is usually the deeper cause below.
If drain continues after replacing batteries, check the event history — a stuck-open sensor or rapid polling loop burns through batteries in days.
Error 2 often clears after cleaning contacts and resetting. Try these steps at least twice before assuming hardware failure.
Battery-related failures are almost always flagged too late — the device degrades silently for days before the app catches up to what's actually happening.
