Query: Battery dies fast

I got this for Christmas last year and was so excited that the kids could vacuum under the table. It lasted about 4 months and it didn't hold a charge for very long, just like other people said. We are in the market for a different type of dustbuster this year, but NOT this one. We DO NOT recommend, and wish we had seen everyone else's reviews before buying last year.
