Dyson Vacuum Not Sucking Up: Possible Problems and Solutions

Dyson Vacuum

Finding out your vacuum isn’t working can be pretty frustrating, especially when you don’t know what to do about it. Even if you’re not that handy, there are some things you can check on your own before taking it in to be serviced.

If your Dyson vacuum cleaner has lost its suction power, don’t worry – we’re here to help! Read on for some tips on how to troubleshoot and fix the issue.

Inspect The Problem

1. Inspect the Roller

If your Dyson isn’t sucking, check the roller first.  As with any electrical device needing servicing, you should ensure the vacuum is disconnected before beginning the inspection.

To have easier access to the roller, you should invert the machine. Next, remove debris from the roller, such as thread, cotton, or hair. This area collects dust and grime over time, making cleaning difficult.

Your vacuum cleaner’s roller will likely become clogged if you have long-haired family members, carpets with edgings, or pets.

When a vacuum becomes clogged with debris like hair and thread, its suction power and efficiency decline. However, to restore full suction power, remove all tangled hair from the roller.

When the screws are removed, the plate surrounding the roller can be removed without much effort. Even though some Dyson vacuums have three larger crews to hold this plate, it takes a quarter turn to take it off.

2. Verify Filter Settings

A Dyson vacuum’s loss of suction might also be attributed due to a clogged filter system. After inspecting the roller, you should go on to this. When the filter is clogged with dirt and dust, even single-filter versions will stop sucking regularly.

Fortunately, the filters in most Dyson vacuums are washable and reusable, so you won’t need to purchase a new one every time the dirt becomes too thick. Instead, you can remove them, wash them, and reconnect them to the machine.

3. Make Sure the Hose is not Broken

When the wand of a Dyson vacuum doesn’t draw air, a clog in the hose is often to blame.

Remove the suction hose from the canisters inside and look at the suction outside. In this case, the obstruction is likely in the extension wand or the suction hose.

Take the extending wand out and examine it’s inside with a torch. Is your view partly or completely blocked? If so, the problem lies here. The problem must be outside the suction hose if the light is unobstructed.

4. Inspect the Lateral Valve

Your Dyson vacuum cleaner might have a side valve. You can get rid of it by pressing a button next to it on the machine. Try blowing through it at one end to clear any potential obstructions. The valve has to be cleaned if you can’t feel the air on the other end.

5. Look at the Bristles

Although new vacuum cleaners often include sharp bristles, these bristles eventually soften and lose their effectiveness, especially if your vacuum is quite old. If the suction in your Dyson vacuum has diminished, you should give it the once-over to make it seem as good as new. However, if it doesn’t work, you may need to replace the brush bar.


1. Clean the Filters

When you use your Dyson vacuum to pick up dirt and dust, the air is filtered via a filter that prevents bigger particles from entering and clogging the dust bag.

Using your vacuum for an extended time without cleaning the filter can get clogged with debris from numerous layers of oversized items, reducing the suction power.

Keeping your filters in good working order requires:

  • Unplug the vacuum from the wall and turn it off.
  • Take away the filter. See the handbook for the precise position of the filters on your model.
  • Always use cold water while cleaning the filters. The filters shouldn’t be cleaned with any detergent or cleaning solution.
  • Ensure all the filth is gone and water flows freely by washing thoroughly.
  • Put the filters in a warm spot for at least 24 hours to dry. Never put it in a microwave or tumble dry.
  • It’s time to put the filters back in place.

After replacing the filters, you can use the vacuum to see whether the suction has restored.

2. Clean the Brush Bar

If your vacuum’s brush bar, which makes contact with the surface to be cleaned, becomes blocked or jammed, the suction power of your device will be compromised.

  • Simply by using a manual lever instead of an electric motor, the brush bar can be easily cleaned.
  • Stop the vacuum and take out the brush bar so you may examine it more closely.
  • Remove any obstructions and give the brush bar another go.
  • If your model has a brushbar, disassembling it may need consulting the brand’s handbook.
  • After reassembling the device, test to see whether it can suction again.
  • Remove All Obstacles From The Wand And Its Airways
  • If your upright Dyson loses suction, you should examine the wand and the hose for clogs.
  • Follow the instructions for your specific model, disconnect the hose and wand, and then use a long, thin, blunt instrument to clean out the vents and the inside of the rod.
  • When clearing the vacuum, take care not to check the interior.
  • There’s no need to use a cloth to clean the inside; remove any large items that might obstruct the vents.

3. Clean the Roller Head

Dyson vacuums with a soft roller head can resolve suction problems by cleaning the head. You should not wash the motorhead if your vacuum has a brush bar or a Direct Drive that uses torque.

  • Take the tip off the shaft.
  • You’ll need to remove the cap and the front and rear brush bars.
  • Use only cold water while cleaning the brush bars. The plug at the end doesn’t need to be cleaned.
  • Carefully sweep away any visible dirt and dust.
  • Take the bars out of the water and let them dry in the open air for 24 hours while they are standing up.
  • It is time to put the bars back up again, but first, you must make sure they are dry.
  • Once you have cleaned the roller bars, test whether the vacuum’s suction strength has returned to normal.

4. Contact Dyson

If you’ve tried all of them and still have problems with your vacuum’s suction, don’t hesitate to contact Dyson’s customer service. Call for an in-person service call if the vacuum’s problem can’t be fixed using the online troubleshooter.

Tips on How to Use Dyson Appliances

It’s essential to choose the correct model. Depending on your house’s square footage and floor material, you’ll need a different vacuum. Selecting the best model will significantly impact how quickly and easily your cleaning tasks are done.

Take the time to adjust your settings appropriately. Use the vacuum’s several settings to their full potential, adapting to the many floor types you may encounter.

Be sure to give your vacuum cleaner routine maintenance. To keep your vacuum running smoothly for as long as possible, do regular maintenance as directed in the company’s handbook.


Why is my Dyson Vacuum not Sucking Up Anything?

If your Dyson vacuum suddenly stops sucking, the problem is almost certainly with the air duct. Dirty or old filters may drastically diminish the suction force of a Dyson vacuum. Often, a brand-new Dyson filter is all that’s needed to fix the issue once and for all.

How do you Reset the Suction on a Dyson Vacuum?

If your Dyson vacuum has a malfunctioning digital motor motherboard, turning off the power and turning it back on can reset it. To put it more simply, this involves repeatedly cycling the vacuum’s power on and off for a long time.

Do Dyson Vacuums Lose Suction Over Time?

After several hours of vacuuming, the filter can be clogged with numerous layers of heavy debris and may restrict the airflow. When this happens, the vacuum will lose its ability to provide suction, which can be frustrating.

Why is my Dyson not Working?

At first appearance, the most typical causes are that the Dyson battery is either too old, completely depleted, or improperly installed. The lid on the vacuum cleaner’s dust bin is not closed. There is either a disconnect between the Dyson filters, or the filters themselves are blocked.


It’s not unusual for a Dyson vacuum to stop sucking, but with these troubleshooting tricks, you can usually identify and resolve the problem. Maintaining your vacuum regularly will prevent this problem from occurring again.
