Query: Stopped working after 2 weeks!

I should have listened to others reviews regarding long term use. It worked amazingly well...for 2 weeks. Then suddenly it kept quitting while I'd be in the middle of vacuuming (after only 5min or so), and now it won't pick anything up. I've cleaned it out to make sure it isn't clogged. It just won't work.I'm sorry to say it was a major waste of money.
