Why Does My Vacuum Cleaner Blow Out Dust

The remnants of the filter are in the bin.

Why does my vacuum cleaner blow out dust.

Air should come back out since it sucks it in and it has to go somewhere. For a vacuum to do more harm than good it has to be a really old vacuum cleaner that has never been cleaned she says. There are two ways this can happen. If an upright cleaner is spitting everything out it means that the brush roller is ejecting everything.

But dirt should stay either in the bag or the bagless container. There are vacuums that have more hepa filtration for taking out small particles but if you are seeing dirt blow back out the vacuum is either broken or the bag is full. My shop vac was blowing dust out the back because there s supposed to be a filter on that plastic frame. In my case the replacement filter names were printed right on the vacuum.

In general most vacuums do take up more dust dirt and allergens. Yours may vary but a lot of shop type vacuums use them. While many vacuum cleaners have other features or options that enhance this basic purpose the general idea is the same to clean the floor. I ve cleaned out my vacuum thoroughly of all clogs i can literally see straight through every hose including the tiny one that s a connector to the hose from the very bottom that s screwed in and there s no switch seen anywhere to blow it out instead nor any way to reverse the hose.

So if you re vacuuming up dry materials and suddenly you see dust flying out of the vacuum here are a few issues and why it might be causing the dust to be spraying all over. If the vacuum cleaner starts to blow dirt back out of the unit instead of suctioning it up there are various possible reasons why.
