RobZone Robee Plus 14.4V Ni-MH Replacement Battery 3000mAh

RobZone Robee Plus — 14.4V Ni-MH Replacement Battery

This is a 14.4V 3000mAh Ni-MH replacement battery for the RobZone Robee Plus robotic vacuum cleaner. It fits the Robee Plus directly and restores the motor and cleaning system to operating voltage. Capacity is rated at 3000mAh (43.2Wh) — matching the original specification.

• Robee Plus compatibility: The Robee Plus runs its drive motors and brush roll from a single 14.4V Ni-MH pack. This cell matches that voltage rail and the physical pack dimensions (179 × 51 × 52mm), so the connector and bay fit without modification.
• Bench tested on actual hardware: We cycled this cell through repeated charge and discharge runs on the Robee Plus platform. The BMS held cutoff correctly at low voltage and the vacuum's charging circuit accepted the pack without fault codes or interrupted charging.
• Dock charging habit on the Robee Plus: Do not leave the Robee Plus sitting on the dock continuously between cleans. Ni-MH cells in robotic vacuums develop capacity fade faster under constant trickle charge than under normal charge-then-remove cycles. Charge to full, then lift it off the dock.

Suction dropping before the battery indicator reaches low

Ni-MH cells under load show voltage sag before the pack is genuinely depleted. On the Robee Plus, a partially blocked filter forces the motor to draw more current than rated — this accelerates voltage sag and the vacuum loses suction early even though the indicator still reads mid-level. The fix is not the battery. Check and clean the filter first. A clear filter reduces motor draw and the voltage sag disappears at the same state of charge.

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

This is a BMS overcurrent trip, not a faulty battery. When suction is restricted — blocked brush roll, clogged filter, or debris jam — the motor pulls sustained high current and the BMS cuts the circuit to protect the cell. The vacuum restarts once the BMS resets, usually within 30–60 seconds. Clear the blockage before restarting. If the cutout repeats on a clean machine, check that the pack voltage reads at least 14.4V fully charged before ruling out a cell fault.
