When it comes down to vacuum cleaners, few do it better than Dyson! There are plenty of fantastic Dyson vacuums to choose from, each with unique features and abilities. Whether you go cordless or robotic, your dirty floors are in good hands – as long as you have suction power, that is! 

When a Dyson vacuum has lost suction power, it is typically due to a blockage or dirty filter. However, there are six main types of Dyson vacuums, which vary in design. Due to this, the process of finding and addressing the cause of reduced suction power will vary across Dyson’s vacuum range. For example, battery issues only affect cordless models. 

If your Dyson vacuum has lost suction power, we’ve got the answer to your problems! In this article, we’ll guide you through the causes and fixes for suction issues.

Regardless of your type of Dyson vacuum, we’ve got the answers you’re looking for!  

Why Does My Dyson Vacuum Has No Suction Power / Lost Suction? 

With vacuum cleaners, suction power is one of the most crucial factors. After all, you’ll have a hard time cleaning without the appropriate suction power. While Dyson vacuums are among the best available today, these vacuums are not impervious to certain issues. 

One such issue is, of course, the loss of suction. When it comes down to this issue, there are a few common reasons that can cause a loss of suction.

Blockages in the hose or any attachments can commonly result in reduced suction power. Dirty filters or collection bins can also result in suction issues.

To find the root of this issue, you typically need to disconnect the hose and any attachments from the vacuum cleaner itself.

This will allow you to determine where the issue is located and address it properly. With Dyson vacuums, however, you’ll first need to determine the type of vacuum you have! 

What To Do When Your Dyson Vacuum Has Lost Suction?

What you do when your Dyson vacuum loses suction will ultimately depend on the type of vacuum you have.

There are six main types of Dyson vacuums: cordless stick vacuums, multi-direction vacuums, upright vacuums, canister vacuums, handheld vacuums, and robot vacuums. 

First, we’ll look at common fixes for Dyson vacuums that have lost suction. We will do this according to the type of Dyson vacuum you have.

In the following section, we’ll take a look at how you can troubleshoot your Dyson vacuum in the event that these common fixes don’t work! 

Dyson Cordless Stick Vacuums 

With cordless Dyson vacuums, when you lose suction power, you will need to check the hose and extension wand for blockages.

You should also check the filter and wash it if needed. If one of these issues was not causing the loss of suction power, it could be due to the battery. 

Cordless models require a battery to operate. Over time, this battery can weaken and can even result in a loss of suction power.

If you need to replace your cordless Dyson’s battery, you’ll be able to do this using our this post. 

Multi-Direction Vacuums 

With Dyson’s multi-direction vacuums, a lack of suction power is typically caused by a blockage. You’ll want to remove any accessories, such as the wand extension and cleaner head.

You should check these for blockages. You should also check the vacuum’s inlet for a blockage. Furthermore, you’ll want to check the dirt container for any blockages. 

Upright Vacuums

For those with Dyson’s upright vacuum models, the first step to address a loss of suction is to check the filter. This can be washed and dried before being put back into the vacuum.

If the suction issues, you’re experiencing, persist, you’ll want to troubleshoot the issues further using Dyson’s official website – we’ll take a look at this in the next section. 

Canister Vacuums 

For those with Dyson canister vacuums, you will first want to check the hose or extension wand for blockages. If neither of these is clogged, chances are the loss of suction is due to a fault with the vacuum itself. 

You should then proceed to check the vacuum’s air filter. Again, this can be washed and dried. However, if cleaning the air filter also does not solve the issue, you’ll want to perform a more in-depth troubleshoot using Dyson’s official website. 

Handheld Vacuums 

If you own a handheld Dyson vacuum, you’ll want to disconnect any attachments to determine the cause of low suction power.

With the attachments disconnected, check the inlet’s suction power. If it’s strong, you’ll need to check the attachments for any clogs or blockages. 

However, if the inlet’s suction power is weak, you’ll need to check the vacuum itself. Remove the handheld vacuum’s filter and dirt container and check these for faults.

You may need to wash the filter. If you do not fix the issue, you’ll want to troubleshoot the issue further using Dyson’s support page. 

Robot Vacuums 

If your Dyson robot vacuum is struggling to pick up dirt, it’s likely a sign that you need to wash the vacuum’s filter. You will need to remove the vacuum’s bin and then wash the filter.

However, if this does not fix the issue, you’ll want to troubleshoot your specific model further.
