why does my dyson vacuum smell


A fresh-smelling vacuum is essential for maintaining cleanliness in your home. However, a common problem faced by Dyson vacuum users is the unpleasant odor emanating from their machine. The cause of this odor is usually a buildup of bacteria caused by lack of maintenance. In this blog post, we will explore the causes of odor in Dyson vacuum cleaners and provide tips on how to get rid of bad odors and prevent future buildup.

Why Does My Dyson Vacuum Smell Bad?

There are several reasons why your Dyson vacuum cleaner may develop an unpleasant odor:

Dust Accumulation

Dust accumulates over time on the surfaces of your vacuum, particularly on the filter and brush rollers. This can cause your machine to emit an unpleasant odor.

Clogged Filters

Clogged filters not only reduce the suction power of your Dyson vacuum, but they also trap bacteria leading to bad odor.

Overused Brush Rollers

Overused brush rollers tend to accumulate debris and dirt which can cause bad odor.

Accumulated Pet Hair

If you have pets, their hair can collect in your vacuum cleaner and become a breeding ground for bacteria, thereby causing bad odor.

Blocked Dirt Bins

If the dirt bin is not emptied regularly, debris can accumulate and cause bad odor.

Malfunctioning Motors

If the motor is not working optimally, it may cause burning of dust and debris leading to bad odor.

How to Get Rid of Bad Odors in Your Dyson Vacuum

Tips for Maintaining Your Dyson Vacuum to Prevent Odor

Here are some tips for maintaining your Dyson vacuum:

Regular Cleaning of Filters, Brush Rollers, and Dirt Bins

Regular cleaning of the filters, brush rollers, and dirt bins can prevent odor and prolong the life of your vacuum cleaner. A simple cleaning routine can involve cleaning after every use or once a month depending on usage.

Proper Storage Techniques

Always store your vacuum in a cool, dry place to prevent moisture buildup which can lead to odor-causing bacteria to grow.

Frequent Replacement of Filters

Filters on a vacuum cleaner should be replaced every six months. If the machine is used daily, it’s best to replace the filter every three months to prevent odor buildup.

Cleaning Brush Rollers

Remove hair, debris, and other materials from the brush rollers by cleaning them regularly to prevent build up of bacteria.

Steps to Clean the Machine

To get rid of the bad odor in your Dyson vacuum, follow these steps:

Cleaning the Filters

To clean the filters, remove them from the vacuum, and soak them in warm water for 15-30 minutes. Rinse them with clean water and set them aside to dry completely before re-installing them.

Cleaning the Brush Rollers

To clean the brush rollers, detach them from the machine and remove any hair, dirt, or debris. Use a brush that is designed for the roller’s bristles to clean them thoroughly without damaging them.

Cleaning the Dirt Bin

To clean the dirt bin, remove it and empty the contents into a trash bin. Wash the bin in warm, soapy water and then rinse it with clean water. Allow the dirt bin to air-dry before attaching it back to the vacuum cleaner.

Running Vinegar Solution to Eliminate Odor-Causing Bacteria

Mix one-part vinegar with three parts water and pour into the dirt bin. Turn on the machine and let it run for 30 seconds, then pause it and let the solution sit for 10-20 minutes. Afterward, turn on the machine again and repeat the process until the odor disappears entirely.
