Perfect
The last time I bought a new vacuum, I did not realize all I had to do was change the battery. The Battery for Eufy RoboVac 11S, 11S Plus, 11S Max saved me from making that mistake again. It was easy to install, charged quickly, and brought my RoboVac back to life like it was brand new. The performance is strong, and it holds a charge well, making my vacuum run smoothly through a full cleaning cycle. A simple and affordable fix that worked perfectly.

Battery power AGAIN!
Fits and works perfectly. I've had this in my Roomba J7+ for a week now and it works perfect. I use my roomba pretty consistently every day and over the last few years, the battery it came with just started going out to the point that it wouldn't last longer than 30 minutes without a charge. As soon as I popped this in, that stopped being a problem and I can vacuum my whole condo each morning again. So happy to find something that can save my favorite smart home device!

J7+
Searched far and wide for J7+ battery replacement, and finally found it! Other batteries didn't work (despite being labeled compatible with the J7+). And OEM batteries from iRobot have been out of stock for months with no replenishment date. Thank you for bringing life back to my J7+ vacuuming robot!

Does not last!
Worked for 6 weeks and then my Roomba would give code error 19. It was unable to fully charge after 249 minutes. Would not recommend! Waste of money.

Just short of home. 🤣
Omg my Roomba, is 2 years old and had the original battery, it wasn't charging, and would take 6 hours to vacuum the house. So I replaced the battery, wish I had done so after I bought it, now it the new higher capacity battery the unit has had no issues and it completes a 2x sweep in an hour. It was simple to replace.

Perfect fit and a great battery.
Easy to install and has cut the amount of time it takes my iRobot to vacuum my home from just over 4 hours (due to frequent recharging breaks) to just under 2 hours with no charging breaks.

Saved My Roomba!
I thought my Roomba was dead for good after sitting unused in the basement for months—totally drained battery. I was ready to toss it and buy a new one, but my daughter told me she had replaced the battery in hers with one she found here and it worked great.I found the same one, ordered it, and proud to say I replaced it myself (lol — it was super easy!). Just make sure you check your model number and order the right one for your Roomba.So far, it’s working perfectly, and I love that it comes with a seller guarantee — hopefully I won’t need it, but it’s good peace of mind!
