The air duct of bag filter is blocked. For example, if the hose, suction head or suction port is blocked by paper balls, cotton wool and other garbage, the suction of the vacuum cleaner will also be reduced or completely disappeared.
The main body of the bag filter may be air leakage caused by unsealed accessories. There are two situations: the air inlet of the main machine in the main machine cavity of the bag filter is improperly assembled, or the rubber block or rubber ring around the main machine is improperly placed; Or the rubber seal is aged and displaced, which leads to the airflow flowing out from the edge of the main engine tuyere and the wind pressure is reduced. Solution: promise to open the main engine cavity to eliminate the above phenomenon, or replace the rubber block and rubber ring.
The excessive accumulation of dust in the dust bag of the bag filter leads to the blockage of the filter hole, which makes the air flow head not smooth, which leads to the reduction or even complete disappearance of the suction force of the bag filter. Solution: Just clean up the garbage in the dust bag.
