Query: works great- for a while!

I really love this little vacuum, has everything I want in a small lightweight vac. I love having onboard tools and hose, BUT, this is the second one in less than 2 years, and there is something wrong with a vacuum that breaks that quickly. The first one the roller brushes stopped turning after 3 months, this one has almost stopped working at all. One of the motors is obviously dead. Fortunately because of our experience with the first one we bought the extended warranty. Back it goes. I don't know what I'll get when this one dies again, but it won't be this one again!
