4.0 out of 5 stars Not all ROOMBA problems are (dead) battery related, October 27, 2008

By	Thomas E. Hudson "THudPHud" (West Linn, OR USA) - See all my reviews (REAL NAME)

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.

2.0 out of 5 stars This Makes Three Batteries, July 22, 2008

By	dalefl "dalefl" (Here) - See all my reviews

I have now had to order my third battery for this Roomba. Like another poster the first one died within a year. This time it lasted about 1 1/2 years. At $50 a pop that is ridiculous and, after reading complaints here and on other sites, makes me wonder if it is planned that way, a vacuum conspiracy. As funny as that sounds, it is also based on experience. I have given two Roombas for Christmas presents and the same thing happened to them. They both went down before 6 months was up. I have yet to read a review in which the battery lasted more than a year. If this was a car company they would be under Federal investigation. They know they've got you over a barrel and I'd be willing to be that they earn the vast majority of their money through replacement batteries, etc.

Well, since the thing is worthless without it I am forced to buy yet another battery. That's three in less than three years. There's definitely something fishy going on here. How else can you explain the fact that they keep producing defective batteries? As I said, in any other industry this would be enough cause for a recall.

On another note, the vacuum works great when it works. But we are now approaching the point in which we've paid more for the replacement batteries than we did for the entire vacuum package. Not good business and if this battery fails I will not buy another.

3.0 out of 5 stars Battery is itself is ok, August 25, 2008

By	Patric Lagny (Inglewood, CA United States) - See all my reviews (REAL NAME)

The battery itself works like a new one, what else can one expect from a battery, so there's not much to say. However I agree with the other people here. I had this Roomba not quite 2 years and used it maybe every 1-2 weeks to clean under the bed and sofas. It's ridiculous that the battery died after such a short time. I was thinking about buying a new roomba instead of the battery, but when I learned that I would have the same problem after a year or two I decided against it and bought the battery instead.
