I believe on your Dirt Devil, whole house vacuum there is a secondary filter in the enclosed housing where the dirt bag is kept. This needs to be cleaned at least once a year, I clean mine every spring when I install another dirt bag for the upcoming season.
I would open the housing cover and remove the dirt bag, behind this bag is a secondary filter that is stationary and must be removed and cleaned every once in a while. This should help with the vacuum suction issue.
