Query: Clogs all the Time

I was very excited to get this vacuum since I would be using to clean a large room with wood floors and a couple of area rugs. It did great on the area rugs, but on wood floors it just blew around the dust. Then after a few months, it kept getting clogged and leaving dust balls all over the floor. It also lost its charge faster.
