UCI On-Campus Housing Problems

I have had a Roomba for nearly a year, and it really is a gods-end for cleaning carpets, in particular with cats around. It also frees up my time. I have it scheduled to clean during the day when I'm not home.
A couple of weeks ago, my Roomba decided to break down. It didn't hold a charge in the battery anymore. I first thought maybe the battery is broken, so I got a new battery. But, no such luck.
So, I decided to contact iRobot customer support, giving them this description of the symptoms:

After resetting the charging system, the Roomba power light is red. After about 20 hours, the power light turns green, but only a light green, not the bright green that indicates a charged battery. When I take the Roomba off the power adapter, the power light goes out. And the Roomba does not start when hitting a clean button.

They determined that based on the symptoms, the Roomba would have to be replaced. Luckily, I am still within the warranty period. So, today, I got an email from iRobot customer support for a warranty replacement.
And they don't require me to send the old unit back:

Because we are not requiring you to return your current unit to us, we ask that you dispose of the robot. This Roomba has been permanently deactivated in our records.

You may strip your Roomba of its parts, such as brushes, brush cover, filter, filter frame, and particle bin, and keep them for spare parts if you wish. It is safe to simply throw away the robot itself.

It is nice to see such good customer support. I was pleasantly surprised.

Update: I have received the new Roomba last week, and it charges the batteries just fine. So it was definitely the Roomba that was broken.
