Infiniton Cleaner 1080 14.4V Replacement Battery CG-990

Infiniton Cleaner 1080 / 1020 / 720 — 14.4V Li-ion Replacement Battery (CG-990)

This is a 14.4V 2600mAh (37.44Wh) lithium-ion battery for the Infiniton Cleaner 1080, Cleaner 1020, and Cleaner 720 robotic vacuum cleaners. It replaces OEM part CG-990, the original cell that powers the drive motors and cleaning system. When the original pack no longer holds adequate charge, this is the direct replacement.

• Cleaner 1080, 1020, and 720 compatibility: All three models share the same 14.4V battery rail, CG-990 part number, and connector pinout. The BMS handshake protocol is consistent across this range, so one cell covers all three.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the Cleaner 1080 platform. The BMS held cutoff correctly at low voltage and accepted charge without fault codes on the dock.
• Dock charging habit for this vacuum: Do not leave the Cleaner on its dock permanently between uses. Robotic vacuums held on continuous trickle charge develop capacity fade faster than those charged only when depleted. Charge to full, then remove from the dock.

Suction dropping before the battery indicator reaches low

This happens when the motor draws more current than the BMS expects — usually because a partially blocked filter forces the motor to work harder. The voltage sag under that extra load triggers a soft power reduction before the fuel gauge registers low. The vacuum appears to be running out of charge early, but the battery is not the root cause. Clean or replace the filter first, then retest — suction should hold steady across the full charge cycle.

Motor cutting out mid-clean then recovering after a few seconds

This is a BMS overcurrent trip, not a dead battery. When suction is restricted — blocked filter, tangled brush roll, or debris lodged in the inlet — current draw spikes above the BMS threshold and the pack shuts the motor off as a protection measure. The few-second pause is the BMS resetting before allowing current flow again. Clear the restriction completely and confirm the brush roll spins freely before charging to 14.4V and resuming use.
