Query: It Doesn't Suck

I've had this unit for some time now and I liked it though my wife found it too heavy. Then I put it away for a few months and when I tried it recently, the battery wouldn't recharge. The unit is dead. So I got on Amazon.com and read the reviews to see what could be done. I found that everyone seems to have battery problems. I'm junking this Shark and switching to a Dustbuster.
