My vaccuum has no more suction

There is no drive belt on a progressive drive vacuum. It is direct drive meaning it is attached via the motor. No vacuum means no air flow somewhere in the unit. Torn bag,Wrong bag, pluged filter under bag.Make sure the opening in the bag is the correct size,too big and it will not seal. Make sure when you close the housing it seals also. No housing seal no vacuum. Kenmore vacuums tend to be plastic housings. Cracks are comon in the wheel housing area. Check there first. Plastic expoxy will work with this fix if so needed.
