It fits the Roomba Combo Essential, Combo Essential 2, and Y011040 variants. Swap it when your robot stops completing full floor cycles or returns to dock earlier than it used to.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRoomba Combo Essential compatibility:\u003c\/strong\u003e\n    The Combo Essential line shares a common 14.4V power rail and a matched ABL-G connector footprint across the Y011040 and Combo Essential 2 variants. The BMS in each unit expects the same voltage profile at handshake — this cell meets that requirement.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full charge-discharge cycle on a Roomba Combo Essential unit. The BMS accepted the handshake without a fault code, charge termination triggered correctly at capacity, and the robot transitioned to dock mode as expected.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging practice for the Combo Essential:\u003c\/strong\u003e\n    The Roomba Combo Essential is designed to return automatically to its dock, but leaving it parked on continuous charge between uses accelerates capacity fade. Once the robot has finished its cycle and is fully charged, remove it from the dock until the next scheduled run.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSuction dropping before the battery indicator reaches low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the Combo Essential, the motor draws more current when the filter is partially blocked — the robot compensates by ramping fan speed, which spikes draw beyond what a degraded cell can sustain at full voltage. The result is visible suction loss while the battery indicator still shows mid-charge. This is voltage sag under load, not a capacity reading. Check and clean the filter first; if suction stabilises, the cell was simply being over-demanded.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-cycle and then recovering on its own\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis pattern is a BMS overcurrent trip, not a power failure. When suction is restricted — blocked filter, full dustbin, or hair wrap on the brush roll — the motor pulls sustained high current and the BMS cuts the circuit to protect the cell. The robot pauses, current drops, and the BMS resets. Clear the restriction, then place the robot back on the dock for at least 15 minutes before restarting to allow the BMS to fully reset before the next cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426443493466,"sku":"BWCS-IRY114VX-1","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426443526234,"sku":"BWCS-IRY114VX-2","price":63.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426443559002,"sku":"BWCS-IRY114VX-3","price":70.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IRY114VX-1.webp?v=1779933287","url":"https:\/\/batteryweb.com\/products\/irobot-roomba-combo-essential-vacuum-and-mop-robot-replacement-battery-144v-3350mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
