Query: Stinky!

After only a few uses with a new bag, smelly odors blow out the HEPA filter compartment. The filter's clean & doesn't smell, the bag's not full. We don't have pet or other carpet odor issues, so we can't figure it out. Only remedy is to change the bag, so we go through them way too quickly. Also, the switch for bare floors no longer works. I'm very disppointed in this product.
