Air Brush Technology

How to repair a vacuum with poor suction?
I have a dirt devil vacuum that’s not very old. A Dirt Devil Action D1 Cyclonic Technology…not sure about the actual manufacturer number. Anyways, it turns on, the brushes rotate powerfully, but the suction sucks. I’ve cleaned the air filter. I’ve tried to check the hose for clogs, but I’m going to have to practically unscrew the whole thing to get to the actual hose. Is it possible it’s just a clog? Or something different?
Try using a shop vac and “vacuuming” the filter. We shake our filter but every once in a while we have to vacuum it. If that isn’t the problem, try taking it to a shop that repairs it!
