It slots into the battery bay using the same connector and cell format as the factory unit. When the original cell degrades and the robot stops completing full floor cycles, this brings the vacuum back to normal operating capacity.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eShared platform across three models:\u003c\/strong\u003e\n    The Optimax UltraClean UV Roboti, SmartClean 2000, and SmartClean V4 run the same 14.4V power rail and use an identical connector housing and BMS handshake protocol — which is why one cell fits all three without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this battery through charge and discharge cycles on the SmartClean platform and confirmed the BMS communicated correctly with the dock charger — charge acceptance was normal and protection thresholds fired as expected under load simulation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit for robotic vacuums:\u003c\/strong\u003e\n    Do not leave the robot sitting on the dock permanently between uses. Continuous trickle charging on lithium cells accelerates capacity fade. Charge to full, remove from the dock, and return it only when the battery needs replenishing.\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\"\u003eThis happens because the motor draws more current when the filter is partially blocked — the BMS reads that elevated draw as a low-voltage condition and begins stepping back power delivery before the indicator reflects actual remaining charge. The battery looks fine on the display, but the cell is sagging under load. Clean or replace the filter first. If suction recovers, the battery is not the root cause. If suction remains weak with a clean filter, the cell has lost enough capacity that its internal resistance is causing voltage sag under normal motor load — at that point, replacement is the fix.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-cycle and then restarts on its own\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a motor fault. When sustained suction restriction — blocked filter, tangled brush roll, or tight carpet pile — forces the motor to pull current above the BMS threshold, the protection circuit opens and kills power. The BMS resets after a few seconds, which is why the robot restarts and continues. Clear the restriction, check the brush roll for hair wrap, and confirm the filter is clean. If the cutout persists with no blockage present, test the resting voltage of the cell — anything below 13.0V at rest indicates a degraded pack that can no longer handle the motor's peak draw.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428007182426,"sku":"BWCS-TVR500VX-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428007215194,"sku":"BWCS-TVR500VX-2","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428007247962,"sku":"BWCS-TVR500VX-3","price":51.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TVR500VX-1.webp?v=1779933850","url":"https:\/\/batteryweb.com\/products\/ionvac-optimax-ultraclean-uv-roboti-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
