I actually bought a brand new brushroll about a year ago and I still can't tell a difference. My sanitronic actually needs a makeover its self. Even though all of the trim, bag etc is the same color, it's pretty much what I've seen people on here refer to as a frankenkirby. It has the sanitronic power plant and handle, but the front nozzle is from an older model. the belt lifter is tan in color and round. The bag, even though less than two years old is the old style, pre-sani-pocket style with the fabric flap covering the metal tube at the top. It is tan and doesn't look bad as it is a Scott & Fetzer bag and everything matches, but it just bugs me knowing that the cleaner itself isn't true to form. I know an original power cord with the brown tips and white cord will be next to impossible to find as well. I have the rubber Bag topper that has the circular kirby logo and Sanitronic written on it, just can't use it.. that's another question... I've seen some Sanitronics with the bag topper on the bag with the writing facing backwards and the plain side on the front and then I've seen some with the writing facing the front.. which way are they supposed to be on?
