iRobot 4905 Battery Review

I have owned a ROOMBA Discovery for about 3 years and am just now finding it necessary to replace the battery. Sure, I had major problems like many others with short battery life beginning when the unit was about 14 months old.

I did a bit of research and found a discussion group that listed a good "try this before you panic" solution. Reset the ROOMBA and refresh the battery. And it worked! How?

Run the ROOMBA until the unit stops. Let it sit for about 15 minutes and try running it again. Do this until it no longer will start up. Then, remove the battery. Flip it over and hold down the POWER button for 20-25 seconds. Release. Flip back over and insert the battery. (I also took this opportunity to thoroughly clean all of the contacts with a Q-Tip and a little rubbing alcohol - letting it dry completely before putting the battery back in). Finally, I plugged the power supply directly into the ROOMBA (not the docking station) and let it charge for 3 days.

NOTE: It may be necessary to do this 2 or 3 times (for a total of 9 days with no ROOMBA), but that time is cheaper than a replacement battery.

Magic. The battery went back to its 50+ minute running time for another 9-10 months or so. At that time I did the refresh thing again and got back to more that 40 minutes running time.

Finally, after a total of 3 refresh/reset cycles, the battery is just tuckered out and won't go longer than 8 minutes no matter what I do. And that's fine... I've had hundreds of good carpet-cleaning runs with the unit. Now, for about half the iRobot cost, I am ordering a new battery from Amazon and expect years of additional use from my ROOMBA.

So, for those who haven't tried this and find that even a new battery doesn't seem to make their ROOMBA run right, give the above a try. It not only does a refresh on the battery, it also resets the ROOMBA so it can take advantage of the power. Can't guarantee it for everyone, but it sure worked for me.
