You have the vacuum serviced, of course! Like any other appliance. My parents built their dream home in 1999 and included a central vac, it needed some TLC in the mid 2010's so they called the company up to service it since it had a lifetime warranty.
Naturally 'lifetime' meant for the homeowner who purchased the unit, so the company often didn't have to honor the warranty as failures were uncommon until the 3rd, 4th or 5th owner. The tech was bemused when he came out to work on it since it was his first warranty call.
