Upright Vacuum Cleaner Lost Suction

\015 Replaced filters, dust bag and attached bounce sheet behind fliter sears part no. 20-86884, for good smell. It runs for a while then I heard a deep roars and the suctions stops. Is the motor dead or just the on/off swtich part no. 4368653 needs replacement. The protector springs is okay. Thanks.

How do I take the brush out?

\015 I have a “Kenmore 31912 Progressive Direct Drive” vacuum. A string is wrapped around the brush. I am able to pull most of it out, except a part that is stuck on the left side of the brush. It is not obvious how to remove the brush assembly to take the rest of the string out. Any advice is appreciated.\015 – Kenmore 31913 Progressive Direct Drive Bagged Upright Vacuum
