Remove the head and empty the bin first
Before you touch the vacuum head, empty the dust bin completely. Most Dyson models have a bin release button near the handle — press it and twist the bin away from the motor unit. Tap the bin over a trash can to dislodge stuck dust, then set it aside.
Next, detach the vacuum head itself. On upright models, there is usually a release button or lever where the head connects to the wand. Press or slide it and pull the head straight down. On cordless stick models, the head often twists counterclockwise to release. Lay the head on a flat surface so you can see what you are working with.
Key Takeaways
- Empty the dust bin and detach the vacuum head before cleaning — most Dyson heads release with a button or twist mechanism.
- Hair and debris wrap around the brush bar; use scissors or a seam ripper to cut it away, working along the entire length.
- Rinse the filter under cold running water and let it dry completely for at least 24 hours before reinstalling.
- Check the air pathway inside the head for blockages by looking through the opening where the head connects to the wand.
- Do not use a washing machine, dishwasher, or hot water on any Dyson part — cold water and air drying only.
Cut away hair wrapped around the brush bar
The brush bar is the rotating cylinder at the bottom of the head. Hair, thread, and pet fur wrap around it constantly, and this buildup is the most common reason a Dyson loses suction. Flip the head over so the brush bar faces you. You will see hair wound tightly around the bristles and the axle on both ends.
Use small scissors or a seam ripper (a small tool with a curved blade, sold in sewing sections) to cut the wrapped material. Work along the entire length of the bar, cutting parallel to the bristles rather than across them. Pull away the cut hair as you go. This takes patience — do not rush or you risk cutting the bristles themselves. Once the bar spins freely by hand with no resistance, you are done with this step.
Wash the head and filter with cold water
Rinse the entire vacuum head under cold running water. Use your fingers or a soft brush to wipe away dust from the bristles, the plastic housing, and the connection points. Pay special attention to the seams where dust collects. Do not use hot water, as it can damage the motor seals and plastic components.
The filter is usually located inside the head or attached to the motor unit — check your model's manual to find it. Dyson filters are typically cylindrical or flat and white or gray. Rinse it under cold water, holding it bristle-side down so water runs through it. Gently tap it to release trapped dust. Never wash a Dyson filter in a washing machine or dishwasher, and never use soap. Let both the head and filter air dry completely — this takes at least 24 hours. Do not reinstall them while damp.
Clear blockages in the air pathway
Suction loss often comes from a clog inside the head or the connection between the head and wand. Look through the opening where the head connects to the wand — you should see a clear path. If you see dust buildup or a blockage, use a straightened wire coat hanger or a plumbing snake to gently push it through. Work slowly and do not force anything, as you can damage internal parts.
Also check the wand itself by looking up from the bottom. Blockages sometimes form where the wand meets the head. If you find one, push it out from the bottom end of the wand toward the head. Once the pathway is clear, you should feel air moving freely when you hold your hand near the opening.
Inspect the brush bar for damage
While the head is apart, look closely at the brush bar. The bristles should be even and intact, not matted, melted, or missing patches. If the bristles are damaged, the bar will not clean effectively and you will need to replace it. Dyson sells replacement brush bars for most models — search your model number on the Dyson website to find the right part.
Also check the axle (the rod running through the center of the bar) for cracks or bending. If the axle is bent, the bar will not spin straight and the head should be replaced. These are the only two reasons to replace the entire head rather than just cleaning it.
Reassemble and test the suction
Once everything is dry, reattach the filter first — it usually slides or clicks into place. Then reconnect the vacuum head to the wand. If your model has a release button, align the head and push down until you hear a click. If it twists, turn it clockwise until snug. Do not force it.
Reattach the dust bin by aligning it with the motor unit and twisting clockwise until it locks. Plug in the vacuum and run it for a few seconds over a hard floor to confirm suction has returned. You should hear a change in the motor sound — it will sound stronger and less strained. If suction is still weak after cleaning, the motor itself may need service, and you should contact Dyson support.
How often to clean the head and filter
The brush bar needs hair removal every two to four weeks, depending on how much pet hair or long hair is in your home. The filter should be rinsed every month and replaced every six to twelve months, depending on use and dust levels. If you have pets or allergies, clean the filter more often.
Check the dust bin after each use — empty it when it reaches the fill line, not when it is completely full. A full bin reduces suction significantly. These straightforward habits will keep your Dyson working at full power and extend the life of the motor.
Frequently Asked Questions
Can I wash the brush bar in the dishwasher?
No. Never put any Dyson part in a dishwasher or washing machine. The heat and water pressure can damage seals, motors, and plastic. Rinse everything under cold running water by hand only.
My filter is still clogged after rinsing. What do I do?
If rinsing does not clear it, soak the filter in cold water for 15 minutes, then rinse again. If it remains clogged after soaking, the filter has likely reached the end of its life and should be replaced. Dyson filters typically last six to twelve months with regular use.
The brush bar still does not spin after I cut the hair away. What is wrong?
Check that you removed all wrapped material — sometimes a small piece of thread or hair remains caught inside. If the bar still will not spin freely, the motor bearings may be damaged and the head will need to be replaced.
How do I know which filter my Dyson model uses?
Check the manual that came with your vacuum or search your model number on the Dyson website. The model number is usually on a sticker inside the dust bin or on the back of the motor unit. Dyson filters are not interchangeable between models.
Is it normal for the motor to sound louder after cleaning?
No — it should sound the same or quieter. If it sounds louder or strained after cleaning, something may not be reassembled correctly. Check that the head is fully locked to the wand and the filter is seated properly. If the noise persists, contact Dyson support.
