The regular power bar and the mini power bar stopped working on my Kenmore Canister Vacuum that is at least 10 years old. I took everything in to the store, and they immediately knew what was wrong. Unfortunately, the part that had broken could not be replaced, but they had a new hose ready to go. Before I left, they completely cleaned my vacuum restoring the suction to a level I hadn't had in years! While I was there, I stocked up on filters as well. I highly recommend them! Thanks!
