Good performing robot vacuum battery

Replacement robot vacuum battery rated at 3000 MAH. It’s replacing a five-year-old 2500 MAH battery. Out of the box, I would say it’s overperforming and currently rates a strong five stars for endurance. We’ll see how it holds up in a month or so….

Worked perfectly!

My eufy 11S robovac stopped working after a few years. It had a solid, red light, and none of the troubleshooting tips seemed to work. I tried to clean out the bristles, empty out the dirt container, nothing was able to fix it. Then I came across an article online that said it could be the battery. I bought this battery at $27, and as soon as I popped it in, the vacuum started working again. Definitely recommend!

Buy a new battery not a new vacuum

Vacuum would only run about 30 minutes. Bought a new battery and it runs for 2 plus hours again.
