Bought this for a Roomba 600 series that had a dead factory battery. Installation of this replacement was very easy. The added additional brushes are a plus. I had an issue with charging the battery for the first time. It was an "Error 5", but that was easily rectified by resetting the Roomba unit. After the reset it allowed the battery to charge fully. I have not had any issues at all since purchasing this battery. A very cost effective fix and upgrade to my Roomba!

bought it for the battery, but those darn brushes don't work!!!! had to throw them away!!!!! So, other buyers... just buy their battery, not the package with the brushes.

This battery pack worked fine in the beginning, but 6 months later of using my Roomba in small rooms 1-2x per week and it is completely dead. Shouldn't it last longer than this?

I had no idea how worn the old battery was. Gigolo Joe is running hard and fast, just like new! You get so used to something and don't pay attention.....now Joe really goes a long and lasts much longer.

Works perfect. We thought we’d have to buy new roomba since we’ve had it for over 5 years but the new battery made it basically brand new! Plus they threw in a few freebies!

I brought this battery or my Roomba vacuum cleaner. I was hesitant at first because it wasn’t a Roombas product, it exceeded all of our expectations I highly recommend this.

Bought these replacements and now my Roomba has new life. Easy to replace. So happy I did this.

When I was thinking of discarding my Roomba, I tried this battery. The price let’s rule out problems and spend money on a new one.
