Schrader cores are the same size as automobile tire valve cores. You may even have a valve cap on your car that has a core remover on the end.
Professionals like the core remover tool that can work under vacuum because it makes pump down time shorter. On a big system, this can be significant. On a small system, the time difference is pretty minor.
The end of your vacuum hose has a valve depressor built in, so you can pump down without removing the core at all. It might take longer... like maybe 5 or 10 or even 15 minutes longer.
How much are they paying you per hour to do this job, anyway?
