Carneo SmartCleaner 610 Replacement Battery 14.4V 3500mAh

Carneo SmartCleaner 610 — 14.4V Ni-MH Replacement Battery

This is a 14.4V 3500mAh Ni-MH replacement battery for the Carneo SmartCleaner 610 robotic vacuum cleaner. It fits directly into the SmartCleaner 610 and restores autonomous cleaning operation when the original cell has lost capacity or failed completely. Voltage and capacity match the factory specification.

• SmartCleaner 610 fitment: The SmartCleaner 610 uses a 14.4V Ni-MH pack at this physical footprint — 90.06 x 69.53 x 45.45mm. The BMS in this robot expects a Ni-MH cell chemistry; swapping to a different chemistry without a firmware-aware charger will cause charge rejection or incorrect cut-off behaviour.
• Bench tested on actual hardware: We ran this pack through full charge and discharge cycles on the SmartCleaner 610 platform. The BMS accepted the cell without fault codes, and the motor draw stayed within the expected current envelope across both hard floor and carpet test passes.
• Dock charging behaviour on Ni-MH: Remove the SmartCleaner 610 from its charging dock once the charge cycle completes. Ni-MH cells on continuous trickle charge from a dock develop capacity fade faster than cells charged only when depleted — this applies directly to how the SmartCleaner 610's dock handles a full pack.

Suction dropping before the battery indicator reaches low

The SmartCleaner 610 motor pulls more current when airflow is restricted — a partially blocked filter is the most common cause. Under that extra load, Ni-MH cells show voltage sag earlier than the charge indicator predicts, so suction weakens while the indicator still reads mid-charge. The vacuum interprets this as normal operation and does not flag a low-battery warning. Clean or replace the filter first; if suction recovers and the battery indicator aligns with actual run behaviour, the cell is fine.

Motor cuts out mid-cycle then recovers after a short pause

This is a BMS overcurrent trip, not a failed battery. Sustained restricted airflow — usually a blocked brush roll or clogged filter — forces the motor to draw above the BMS current threshold, triggering a protective cutoff. The pack resets after the thermal and current conditions drop, which is why the vacuum restarts after a pause. Clear the brush roll and filter, then check that the restart happens normally; if the trip occurs again on a clean filter, measure pack voltage at rest — it should read above 13.5V on a fully charged Ni-MH 14.4V pack.
