We use filter bags in the CanaVac - the Beam was bagless and the
filter, although never clogging, was an awfull mess when you emptied
the bucket.

My central vac is bagless.
It has a motor hanging from the garage ceiling (in a side room) where a
steel 5-gallon-sized bucket captures all the stuff vacuumed up.
