iRobotXLife Extended Life Battery, Blue, 8 x 1 x 3 cm

This is the only choice for a Roomba replacement battery, as it is the genuine article. I wasted money on a cheaper alternative, which failed after a few weeks. You get what you pay for.

The robot works better than new. It is perfect.

Poor Robbie. It's a tough life being a Roomba. It's even worse when you're an old model whose been worked night and day for 5 years with no rest. Something had to give. Well, it was his battery failing that finally allowed Robbie the Roomba to rest for once. However I just slapped this X-Life battery into his old frame and: Boom! He's back in the cleaning business. The battery charges fast and lasts for hours, the house is spotless. It was cheaper than on the iRobot website and delivered well within the quoted time. Great product, great service. I can hear him cleaning and sobbing out in the kitchen right now. No rest for the wicked.

It is a good battery but costs a fortune for what it is!! Makes all the difference to put new battery in but it's needed every 2 years or so so quite expensive to run.

Very happy with this so far and I have had it quite a while now and as the saying goes you get what you pay for. Yes it is expensive but worth paying for

works perfectly for my roomba-several years old

Don't be tricked in to buying other brand cheaper replacements like we were last time. It lasted 6 months - they change the sites regularly so you can't leave feedback.We could tell the difference immediately with this battery. Roomba goes with the energy it used to. Worth paying the extra as it should now last 3-4 yrs instead of months.

Got a roomba for mother's day last year and loved it. But after 6 months the stock battery quit me. I couldn't get Irobot to ship a replacement from America so I looked here on Amazon and found this one. Ordered it and got it very quickly and installed it. My roomba is back at it and running better than ever!
