1. Shorter cleaning runs
If your robot used to finish the whole floor and now returns to the dock halfway through, capacity has dropped.
2. It won't leave the dock
A battery that can't hold voltage under load may show as charged, then shut down on start.
3. Charging errors
Repeated charging error codes can come from the battery, contacts or dock — a diagnostic tells them apart.
4. Swelling or heat
Stop using the robot immediately if the case bulges or the battery gets hot. Bring it in; we recycle damaged cells safely.
5. Age
Most batteries last 2–3 years of daily cleaning. A quality replacement typically costs far less than a new robot.
