How to Fix / Troubleshooting
Safety: Turn OFF the robot and avoid using a visibly swollen or leaking battery.
- 1. Verify charge:
- Charge the robot on the dock for at least 4–6 hours.
- Ensure the charging indicator shows full charge.
- 2. Measure runtime:
- Start a cleaning cycle and time how long it runs before returning to dock or shutting down.
- 3. Inspect battery:
- Open the battery compartment and check for swelling or corrosion.
- 4. Replace battery:
- Purchase a genuine Kyvol-compatible replacement battery pack.
- Disconnect the old pack, install the new one, and secure it properly.
- Fully charge before first use.
- 5. If runtime is still short:
- The main board may be misreading battery levels; professional diagnosis is recommended.
