Query: Very short lifespan

I've had this cute little DustBuster for about 9 months, and must echo the woes of everyone else about the battery life. I BARELY used mine (i.e. a couple times a month), and when I did, it was for no more than 2-3 minutes. Now, even when it's plugged in it only lasts a couple seconds -- and then it won't turn off! (I even unplugged it and took it apart, but the motor kept running.) I enjoyed it in the beginning but it gradually stopped working...so I'm here shopping for a different one.
