Bests & Worsts Reviews from Amazon

I bought the Euro Pro Shark Navigator a month ago, and when I first started using it, I was sooo impressed at how well it cleaned my carpet and left it looking new, but I encountered a problem where the spinning brush part on the bottom of the vaccum does not stay spinning the whole time I'm vacuming. I push it foward it spins, pull it back, it stops. I cleaned out the brush, all the filters,and it still won't run right. I call the company customer service, I get someone from another country (I am in USA) and all he can tell me is to clean out the filters. Thanks for nothing. I already tried that. So I e-mailed the company explaining my problem,they e-mailed me back telling me to call customer service. Thanks for nothing again. so I have a $200 vaccum I have only had for a month and it doesn't work and I can't get any help with it. So Shark Navigator you get 1 star from me!!!!
