Dyson Lost Suction: My Tips to Fix it!

One of the most frequent problems you can encounter with any vacuum is losing suction. This is annoying, right? You got the unit to help you clean up and suck up every piece of dirt from the floor, but it is not doing its job.

When it comes to Dyson, they take pride in their unique Root Cyclone Technology. This technology ensures that the suction of your bagless vacuum will not fade as it gets full. Instead, the dirt goes directly to the dirt container.

However, you can still experience losing suction even if you have a Dyson vacuum. If this happens, there are ways to troubleshoot it, without having to return the product or send it to Dyson to fix it. The point is discovering the source of the problem. The majority of the time, you will be able to deal with it by yourself. So, let’s see what you can do.

Determine the Model

The first step is knowing what type of vacuum you have. Whether it is a canister, an upright or a handheld vacuum influences how you are going to approach fixing the issue. You should also look at how the unit is powered. A cordless vacuum can have certainly issued that a corded does not.

If you know the type and the model of your vacuum, the Dyson website offers you troubleshooting tips for each of their models. But these tips can be presented in a shorter and more efficient way. Since you probably want to fix the issue as quickly as possible and get onto cleaning, here is some advice on how you could solve the problem, depending on the type of your vacuum.

Dyson Canister Vacuum Losing Suction

If you have a canister vacuum, the first step is removing the hose so you would determine whether it is clogged, or the problem lies in the vacuum itself. When you remove the hose, you should place your hand on the inlet and check the suction. If it is satisfactory, then the hose is the problem, and you should unclog it. Take any thin metal string and try to pull out the mass that is obstructing the suction.

If there is an extension wand, it may be the cause of the problem. So, if you determine that the hose is not clogged, check the extension wand.

If you determine that the suction is not satisfactory, the problem probably lies in the filter. If this is the case, taking out the filter, washing and drying it should resolve the issue and the suction should improve.

Dyson Upright Vacuum Losing Suction

If you have chosen an upright vacuum for your home, the troubleshooting process is a bit different. With upright vacuums, the first thing you should check is the filter. Taking out the filter to wash and airdry it should get the suction power back to the level it was initially.

Here is a quick guide with steps that can be applied to almost all Dyson models. First, you need to locate the filter. It is usually above the dirt canister, so you should begin by removing the canister itself. After you did that, there is a mechanism to detach the filter frame (if there is one) from the dirt cup. Then, take out the filter and run it under cold water. Squeeze it and wash it until the water becomes clear. This means you got all the debris out of the filter and it is ready for drying. Never put the filter on a heat source or near a flame to dry it. It is enough to put the filter on a paper towel and let it sit there until it is airdried.

If you need a visual guide, here is a video showing how the process looks like. If you follow this, you should be able to do it easily.

If the suction power problem persists even after you cleaned the filter, you should check the hose and the extension wand if there are any. The problem may be the same as with canister vacuums since clogs are nothing unusual.

Dyson Handheld Vacuum Losing Suction

Handheld vacuums are very popular for quick pickups, and many people have them in their homes. If you notice poor suction, the first step is to remove all the attachments and check the inlet. If the suction is weak, the best thing to do is start disassembling the vacuum by removing the dirt container and filters. You should check all the crevices for debris and remove any build-up you find. Washing the filter can also solve your problem if the steps so far do not help.

Cordless Dyson Vacuum Losing Suction

If you have a cordless vacuum, here is what you should do. First, check the hose, extension wand and other parts for blockage. Then, wash the filter as we described above. If you did all of this and the problem is still there, you should check the battery. If the battery does not have enough power, the suction may suffer. Additionally, if you own the vacuum for some time, the battery may weaken, since there is battery life and your battery may need to be replaced.
