Bought on a whim because it's so much cheaper than buying a whole vacuum again. It was a breeze to install.

Don't go with a pricey "name brand" replacement if this will suit you needs. It was affordable and works great! Review: So far, this battery is working well in my Eufy robo vac 11S - Got this as a replacement for the previous battery in my eufy RoboVac 11S. It fit the battery holder and the connections were just right. Positives: So far, the battery is working well, charging, and giving me the same performance as the previous battery. Fits the Eufy Robo vac 11S Negatives: The battery life is unknown as I have only had it a short while. I got the Eufy 11S in 2018 and have had to put three batteries in it so far. I wish the other batteries would last longer. Maybe this one will?
