Today we made w new customer from Riverwoods. She brought in her Oreck vacuum with poor pick up and a burning smell. We were able to determine that there was so much hair caught on the brush bar that is was causing a burning smell, but that did not fix the orecks poor suction. Upon futher investigation, we found a major clog in the fan housing. Once removed this Oreck is working great and we have a new & happy customer.
