Hi Rain,
Thanks so much for your response to my question. After we read your response we decided to go back to step one and start over. This time we won't cut corners. I am going to order new brushes tomorrow so it will take a few days for us to get the parts and try your suggestions.
Unfortunately, we are in Michigan so bringing the machine into your shop would be a long ride. Thanks again, for taking the time to respond to my email. My husband and I are huge fans of your site. We'll be sure to let you know about our progress.
Sincerely,
Angela and Chris
