Is your Dyson vacuum struggling to suck the dust off your floor? Or, rather unnervingly, has the vacuum been blowing dusty air out instead? This is a serious matter of concern, so it’s time to look into what could be causing such a surprising result. The question is, why does a Dyson vacuum blow air instead of sucking it?
A Dyson vacuum blowing air back out instead of sucking can be a rare instance of the canister being too full. The best way to take care of this is to clean out the canisters, but the problem can persist if there is a blockage in the internal vacuum mechanisms. Therefore, your best bet is to systematically clean the whole vacuum.
Cleaning a vacuum, however, is a little trickier than it looks. Keep reading to learn more about this process. If you are still trying to learn how to do this, we have everything laid out for you in this article!
Why Your Dyson Vacuum Is Blowing Out Air
So, we all know that vacuums work by using a suction mechanism to pull the dust and debris off our floors and into their dust canister. However, in some cases, you may notice air blowing out instead. This typically happens at the back or the sides of the vacuum and is a sign there is something wrong.
Unfortunately, air blowing out of your vacuum is a surefire sign that a clog or something is blocking the flow of air. As a result, the air travels back out, pushing the dust instead of cleaning it. One of the most common causes of this issue is a dirty dust canister, but that is just one possible start. The problem can extend over to all the mechanisms of the vacuum. And the simple way to fix this issue is to clean the vacuum out.

How To Clean Your Dyson Vacuum
Now that we know there is an issue, the next step is to clean the vacuum. This can take some time as there are plenty of parts to consider, so let’s start one by one and approach each part of the vacuum to make sure there is no lasting damage.
Rollers
The roller, or the brush roller, is the part of your vacuum that rolls over the floor while you are using it. This vacuum part is an excellent place to start as it is where obstructions can start to form in the first place. There could be a blockage right here to prevent air from being pulled in, causing it to blow back out instead. So, here is how you can clean the roller:
- Switch off your vacuum completely, and remove any plugs from the power source.
- Turn your vacuum upside down so you can see the roller correctly.
- If the roller is clean, you should not be able to see any hair, string, or dirt/objects jammed inside.
- You can slightly open up the plate held by screws, but don’t take it off completely.
- Use scissors to cut away the hair and tangled dust and fiber.
- Pull out any remnants and make sure there is nothing left behind.
Hair and fur can easily get tangled in your roller, so this is something you may have to check frequently if you have long hair or a lot of pets. You may even ee this if you have a rug that keeps losing fibers or something of that sort. Over time, all of this collected hair and dirt can cause severe damage to the vacuum, so make sure you remove collected hair routinely.
Filters

Another likely issue you may face is that the filters could have something that is blocking them. When filters have a blockage, the movement of the air is wholly disturbed, leading to irregular behavior like air blowing out from certain parts of the vacuum. If the filter is full of dust, you can either replace or clean them. All of this depends on the level of damage and the kind of model you are using.
You can look for the model number to check online for replacements if that is what you wish to do. However, if you still feel like you can make the same filter work, do start by looking for tips in the instruction manual. That way, you will know which filters to clean and how.
In general, follow the instructions to first remove the filter. Then, you will need to clean it out. Instructions will differ depending on the model, so do not neglect to check those out as soon as you remove the filter.
Generally, cleaning the filters involves soaking your filter in water for about five minutes and gently squeezing it out. Do not use any detergent. Repeat this process a couple of times to get all of the dirt out of the way. After that, you can let the filtered air dry completely before adding it to your vacuum again.
Hose
A blockage in the hose can be quite problematic, so you want to take care of it as soon as possible. The hose also carries air through the vacuum, so there is a good chance the issue is happening because of something inside it. Now, how you take care of this also depends on your Dyson Vacuum model.
If you use a canister-based model, you will need to take the hose off and inspect the air. If it is working fine, you know the problem is in the hose, as you have checked everywhere else at this point. You can inspect the hose under the light to see if there are any present blockages. If you see anything, you can use something else to tug and pull out the obstruction. A hanger is an excellent choice for this kind of work.
Canisters
One of the other places to check for issues is the dust canister. A dust canister can get blocked pretty quickly because that is where all the dust lands while you clean. However, you can also easily clean it by emptying out the bin. You can check how to clear the dust canister on your Dyson vacuum by consulting the instructional manual.
Conclusion
You now know how to check your Dyson vacuum should you ever come across dust blowing out instead of being sucked in. We hope you found this article helpful and can now get to cleaning!
