Works perfectly. Nice upgrade. Roomba now runs longer.

These batteries worked well but after 11 months they are down to 20 minutes of vacuum time. 2 batteries in 2 different Rumbas. Not good enough Note: the company read my review and contacted me. They sent me out 2 new batteries to replace the ones I bought. Changing to 5 stars. This is a quality company that actually cares about their customers. Great job!!

Fit perfectly and worked well. Very satisfied

The battery fits perfectly and provides a significant boost in runtime compared to the original. My Roomba can now clean my entire home without needing a recharge halfway through. The installation was straightforward, and it charged quickly. I appreciate the added power, which allows my Roomba to pick up more dirt and debris. The only reason I’m giving it four stars instead of five is that I noticed it takes a bit longer to charge than I expected

I had a Roomba that I admittedly never used for years. I finally moved into a new home a little less than a year ago and decided to finally set the Roomba up. Unfortunately, every time I ran the Roomba it would go for about 45 minutes then die and say "Please charge Roomba." It made no sense to me, as I read the Roomba was supposed to dock if it sensed it had low battery. I thought there might be interference from objects or the dock was obscured or the sensors were broken. I was ready to give up when I decided to just try to replace the battery and see if that worked. And wouldn't you know it, that fixed it! The Roomba now finished its jobs and docks no problem. Sometimes the Roomba will get stuck, but never because of battery issues (mostly getting stuck under furniture). This was an excellent product that is still running strong a few months after purchase. Even if it stops working it was well worth the cheap price I paid.

Battery does install easily and works with the Roomba, but battery life is trash. I’ve given it a few years hoping that more regular use would allow the Roomba to adjust to the new capacity or that a smaller living space would accommodate the poor charge, but no such luck. I get 40 minutes of cleaning before it dies, and the Roomba doesn’t recognize the decreased charge, so the feature where it returns to the base to charge itself essentially no longer exists. I’ve never once successfully completed a job larger than 1 room since purchasing this battery. Stick with OEM batteries.

After several months, it is still going strong. I made sure to charge it a full day before first use. It has been one of the better replacement batteries for my roomba.

Extended the life of a FB find!
