I know that is poor English. The toilet doesn't flush itself.
Someone has to push the lever. But I've had the rooter people out
twice now, and they have used the wire thing on the entire house, and
it took 3 flushes this morning to make everything go down. The rooter
guy looked into an access point and didn't see any backup water, and
the washer drain fine, and nothing else backs up, so I wonder what
makes a toilet flush slowly. What is the chance that the air tube to
roof is clogged in some way?

Maybe everyone in your household, needs to eat more fiber.
