iRobot Roomba replacement 3500mAh Battery + 500 series

I used this for the Roomba 520. Quite an older model but everything fit and worked perfectly. Mine was quite old and was a hand-me-down so I did quite an extensive clean. My old battery was old and corroded, filters were not there, brushes were filled with old pet hair and who knows what else.This kit and a bit of screwdriver turning and a washcloth has my roomba looking and performing like new.Battery:The battery last enough for 3 cycles of my apartment (900 sq ft single story) with some still left in the tank.Brushes:Super easy to install. Fit like OEM.Everything was beyond my expectation and for the price this is absolutely great. If you're looking to rebuild or maintain a roomba vacuum, this is the kit for you.I cannot comment on the longevity due to the amount of time I have had them installed but things seem sturdy and OEM-likeWhen it comes to ease of install, I am an electronics technician by trade, so to me it was 5 star easy. I would say your average joe is looking at a 4 star easy maybe even still a 5. If you're older and Color TVs are still impressive to you, then I'd say you're looking at a 3 star ease.

MISLEADING DESCRIPTION AND PHOTOSI have a roomba 561. The filter is as in the picture. But i received filters that don't fit and a rubber brush that doesn't fit. See pics of my original filter and the one they sent me. I'm highly annoyed. I will edit this review if customer service contacts me and rectifies this problem

I mainly purchased this for the battery because my iRobot roomba 585 was having battery issues. The extra parts were just bonus. The battery went in easily. The extra three-prong spinner thing went on easily and the new brush fit fine. However, the rubber spinner part did not fit in my roomba and the filters don’t match the kind of filter found in my unit. Overall I am satisfied since my primary reason for purchase was battery replacement, however it would have been nice to be able to refresh all of the parts.

Complete waste of money. I bought this in March and it was totally dead by October. So now it's January and I need to buy a new battery since I haven't been able to use the robot in several months.

This was the best money I ever spent. We received the Roomba as a gift 9 years ago but had recently noticed that it would die after about 5 minutes. We thought we were going have to shell out $100's of dollars to replace it but I took a chance and bought this kit and I'm glad I did. We replaced all the parts and now the Roomba (it was reconditioned when it was given to us) runs like new. Highly recommend purchasing this if your Roomba is starting to slow down.

I was only looking for a replacement battery for my Roomba 500-series (557), so the other parts were mostly a bonus. The battery installation was straightforward, and now the Roomba can finally vacuum the whole house again. The old/original battery was only lasting 5-10 minutes. The filters, brushes, etc. in this kit all fit too.(FWIW - The original Roomba battery was Model 3000, 14.4v, Ni-MH, with no amp-hour rating shown.)

I didn't mark longevity because I just put the battery in a few weeks ago. If we're talking about how long the Roomba goes without the battery dying, then I would give it 5 stars. But if that is talking about the life of the battery, I don't know. Anyway, I felt I got a good deal, which included not only the battery (which Roomba company asks $89), but also got new brushes.

Bring your old Roomba back to life! Battery takes full charge and runs as well as new. Make sure to read and follow directions for battery charging. Allow it to fully charge. If you don't have a manual for your Roomba, find one online.All parts fit as well as OEM. Refurbished a 10 year old Roomba for my disabled son on the cheap. Literally like new. Very pleased. Would buy again.
