I know that many people don't really like Orecks because they think that they are too lightweight to do a good job. However, I happen to love mine. It is my favorite modern machine. ( I have many vacuums.) My Oreck is about 3 years old. I have tried to service it and keep it in good shape, but lately it has gotten so hard to push on my area rugs. I have 98% hardwoods and 2 large area rugs. I do use the machine on the hardwoods and it does a beautiful job. I was just wondering if maybe the brushroll needs to be replaced? Could that be the reason for it being hard to push? How often should they be replaced? Are there any more Oreck lovers out there? Tim
