Looking for a Vacuum That Doesnt Blow Air Back Out!

I had Hoovers for years and HATED them!!! I finally saved for a Dyson & love it!! I can't believe I didn't do this sooner. We did Walmart.com site to store as we found that was the cheapest route to go. Good Luck!!

If a vacuum cleaner draws air in, it must also blow air back out.

But yours might not be filtering air correctly. Check to see that your bag is reasonably fresh/empty. An overfull or old/clogged bag will not capture dust as effectively. Also check the seal that seats the bag and make sure it's well connected. Be sure there are no tears or split seams in the bag. And if there are other filters between the bag and exhaust, clean or replace them.

My Dyson has a very efficient filter system that seems to capture pretty much everything. I'm really sensitive to dust, and notice when it gets blown around.

Does it have a bag and is it full? That can blow back dirt.
I have a wonderful vacuum but it's exensive but I've had it for 10 yrs. or so. It's a miele. I'd recommend it anytime to anyone. You will get your money out of it.

It's normal. You can't have it suck air in and not allow it to escape. If it's blowing dust and dirt out, your filters need changed or canister emptied.

We have a Rainbow vacuum and LOVE IT!!

My vaccuum did that once - turned out it was clogged. Make sure everything is clean and it is getting good suction. Otherwise, time for a new one!

Air should come back out since it sucks it in, and it has to go somewhere. 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 Hoover has a folded carboard/paper filter that I can clean as well as a sponge-filter. I am not sure which one is the intake and which one is the output, but both need to be cleaned frequently. Check the manual for your model.

From Wikipedia:
Many vacuum cleaners use HEPA filters as part of their filtration systems. This is beneficial for asthma and allergy sufferers, because the HEPA filter traps the fine particles (such as pollen and dust mite feces) which trigger allergy and asthma symptoms. For a HEPA filter in a vacuum cleaner to be effective, the vacuum cleaner must be designed so that all the air drawn into the machine is expelled through the filter, with none of the air leaking past it. This is often referred to as "Sealed HEPA" or sometimes the more vague "True HEPA." Vacuum cleaners simply labeled HEPA have a HEPA filter, but not all air necessarily passes through it. Finally, vacuum cleaner filters marketed as "HEPA-like" will typically use a filter of a similar construction to HEPA, but without the filtering efficiency. Because of the extra density of a HEPA filter, HEPA vacuum cleaners require more powerful motors to provide adequate cleaning power.

I had been happy with Hoovers for many years, but I returned the last two or three after a few months because they stopped working right ( one turned itself off after a 10 X 10 area -over heating! - I could not put up with that- I have a whole house to do)
Costco took them back NO QUESTONS ASKED...
I did spend a little more and got a dyson, It saves me alot of time and fustration... I never have to sit on the floor and take it apart to fix a belt that fell off when it grabed a shoelace or something... It spins with noise if caught, but resets itself... YeaH...
It has a bare floor and carpet setting, so you can do both.
( Maybe that setting is not working on ours)
I think every baby should come with a dust buster vacume...
Take care,

It's full or possibly a something blocking the intake passageway.

Dyson! Best money we ever spent!

Try a dyson. They are pricier than some others but work amazing and last forever. Good luck!
