How to Fix the Suction on a Dyson

When a Dyson vacuum cleaner doesn’t have enough suction power, it can be frustrating. However, there are a few things that can be done to fix this problem and have your vacuum working like new again.

First, check the filter on your Dyson to see if it needs washing. If the filters are clogged, it can obstruct airflow and cause the vacuum to lose suction power.

Check the Filter

How to fix the suction on Dyson? To keep your Dyson performing at its best, you’ll need to regularly clean the filter. This can help you keep the vacuum’s air quality at its best by removing the particles from your home that might be causing your allergy symptoms and other problems.

Most Dyson machines have a pre-motor filter, located near the cyclone and colored purple to make it easier to spot. This is where you’ll need to remove the filter for cleaning, then rinse it under running water and tap it until all of the dirt has been removed.

You should leave the pre-motor filter to dry for at least 24 hours before putting it back into your machine. This helps prevent moisture from damaging the filter and reducing its lifespan.

Some Dyson machines also have a post-motor filter, which is located on the back of the machine and is a HEPA filter. To clean the post-motor filter, follow the same steps as the pre-motor filter, but only let the water run through it a few times until it’s clear.

Check the Motor

The suction on a Dyson may not function properly if the vacuum’s motor is broken. This can be the result of a blocked airflow, an oversaturated filter, or a problem with the powerhead and hose.

To fix the issue, you’ll need to disconnect your vacuum from its power source and check its motor. This includes removing the plug from the wall socket if your Dyson is a corded model or unplugging the battery pack on cordless models.

If you’re unsure whether the vacuum’s motor is broken or not, you can try electrically testing it using a digital multimeter and an ohmmeter. Place the test probes on the motor’s wires, and watch for a low resistance reading.

If you get a higher reading, it’s likely that the motor is broken and will need to be replaced. This is also a good time to check the motor’s bearings. If you see that they’re worn down, consider lubricating them.

Check the Hose

If you’re struggling to get your Dyson vacuum to work properly, the most likely cause is a bad hose. A clogged hose can limit the amount of dust and dirt your vacuum can pick up, which means it won’t give you the same level of suction power.

Fortunately, it’s a relatively simple process to check the hose on your Dyson. Just pull the hose out of the black plastic piece and take note of any debris or old glue that may be stuck on the hose.

Next, use a utility knife to scrape away any pieces of rubber and glue that aren’t black plastic. This will allow you to clean the hose end and make it fit into the gray business end again.

Once you’re done cleaning the hose, grab your screwdriver and a hammer to remove any broken clamps or metal straps that are holding the hose in place. This will prevent it from getting ripped or twisted. It will also make it easier to install a new hose.

Check the Brush Bar

The brush bar on Dyson cleaners is an important part of the vacuum’s cleaning process. It helps to rotate dirt and animal hairs as they are swept up.

If the brush bar is stuck or clogged, the suction will stop. When this happens, the brush bar must be removed and cleaned.

There are several ways to remove and clean a Dyson brush bar, but first you need to ensure that the brush bar button is turned on.

This button is usually located near the vacuum’s handle or in a slot on its side, and pressing it will reset the brush bar. You should then flip the vacuum back upright, plug it in and power it on.
