That is your problem, 100%, no question.Changed the bags. It’s sucking a little better. I also have a plug missing in the bottom of the vacuum. Could that have something to do with loss of suction ?
Heck if this were a recurring problem I would get some aluminum Flashing, Silicone sealer and self drilling srews and gluse an screw the flashing over the plug and hole.Whenever we have a vac whose suction is lower than normal it is always a missing or cracked or unseated plug (mentioned above). We keep 6 of the $1.50 part on hand for such situations and that is first thing we check.
I’ve got a vacuum that is not sucking
