How To Clean Dyson Dc40


Keeping your Dyson DC40 clean is essential for maintaining its performance and prolonging its lifespan. Regular cleaning not only ensures that your vacuum operates at its best but also helps to prevent clogs and keep the air in your home fresh and allergen-free. In this article, we will guide you through the step-by-step process of cleaning your Dyson DC40, from removing tangled hair to cleaning the filters, so you can keep your vacuum in top condition.

Gather Your Supplies

Before you begin cleaning your Dyson DC40, it’s important to gather all the necessary supplies. Here’s what you’ll need:

1. Clean, dry cloths or paper towels
2. Scissors
3. A flathead screwdriver
4. Mild detergent or dish soap (optional)
5. A basin or bucket (optional)

Step-by-Step Guide on Cleaning Your Dyson DC40

1. Disconnect and Prepare the Vacuum

Start by unplugging your Dyson DC40 from the power outlet. Remove any attachments, such as the hose or brush bar, so they don’t obstruct your cleaning process. This will also give you better access to all the parts that need cleaning.

2. Remove Tangled Hair or Debris

Over time, hair and debris can get tangled around your brush bar, preventing it from spinning effectively. Lay the vacuum on its back and use a pair of scissors or your fingers to carefully remove any entangled hair or debris. Be cautious not to damage the brush bar or cut yourself during this process.

3. Clean the Dustbin

The dustbin of your Dyson DC40 holds all the dirt and debris it collects. Empty the dustbin by pressing the release button, typically located near the handle. Dispose of the contents in a trash bag. To thoroughly clean the dustbin, use a cloth or paper towel to wipe out any remaining dirt or debris. For stubborn residue, you can rinse the dustbin with mild detergent or dish soap and warm water. Allow it to dry completely before reassembling.

4. Clean the Filters

Filters play a vital role in trapping dust and allergens, so it’s essential to clean them regularly. The Dyson DC40 includes two filters: a pre-filter and a post-motor HEPA filter.

To clean the pre-filter:
– Locate the release catch and remove the filter cover.
– Take out the pre-filter assembly.
– Tap it gently against the trash bag or sink to remove any loose dust and debris.
– Rinse the pre-filter under cold water until the water runs clear.
– Squeeze out any excess water and allow it to air dry completely before reinstalling.

To clean the post-motor HEPA filter:
– Unlock the filter cover and remove the filter.
– Use a soft brush or a vacuum cleaner with a brush attachment to gently remove dust from the surface.
– Rinse the filter under cold water until the water runs clear.
– Squeeze out any excess water and leave it to air dry completely.

5. Inspect and Clean the Brush Bar

The brush bar of your Dyson DC40 can accumulate debris and hair, significantly reducing its effectiveness. Use a flathead screwdriver to remove the end cap of the brush bar. Carefully remove any tangled hair or debris, taking caution not to damage the bristles. Once clean, reinsert the end cap and make sure it is securely fastened.

6. Wipe Down the Exterior

To keep your Dyson DC40 looking fresh and clean, use a damp cloth or paper towel to wipe down the exterior surfaces of the vacuum. Avoid using harsh chemicals or abrasive cleaners, as they could damage the plastic.


Regular cleaning of your Dyson DC40 is necessary to maintain its performance and prolong its lifespan. By following the step-by-step guide provided, you can easily clean your vacuum, ensuring optimal suction power and clean air in your home. Don’t forget to schedule routine maintenance and filter replacements as recommended by the manufacturer to keep your Dyson DC40 performing at its best for years to come. Happy cleaning!
