The Dyson V11 is a strong cordless vacuum, but it only stays strong when air can move freely through it. When power drops, run time feels short, or the vacuum starts to sound rough, the problem is almost never the motor. It is dirt build up.
Hair wraps the brush. Dust packs the filter. Fine grit coats the bin and air path. None of this happens all at once. It builds slowly until the vacuum starts fighting itself.
This guide shows how to clean a Dyson V11 from top to bottom the right way. No tools. No force. Just simple care that brings the vacuum back to full strength.
Why the Dyson V11 Needs Regular Cleaning
The V11 moves a lot of air through a tight space.
That design gives strong suction, but it also means small clogs have a big effect.
A dirty filter alone can cause pulsing, weak pull, or sudden shut off.
Hair in the cleaner head can slow pickup even when the motor feels strong.
Cleaning keeps airflow fast and the motor cool.
How Often You Should Clean a Dyson V11
Light use homes should do a full clean once a month.
Homes with pets or long hair should check the head weekly.
Empty the bin after each clean.
Wash the filter about once a month.
If the vacuum pulses or feels weak, clean it right away.
Before You Start
Turn the vacuum off.
Remove it from the charger.
Let it cool if it was just used.
Work near a trash can in good light.
Step One: Empty the Dust Bin
Hold the vacuum upright over a trash can.
Pull the red release lever straight down.
The bottom door opens and the inner sleeve slides down.
Dirt and hair fall out by gravity.
If debris sticks, tap the bin lightly.
Push the lever back up until it clicks.
Do not let dirt pack past the max line. Overfilled bins reduce suction fast.
Cleaning the Dust Bin
The bin does not need washing every time.
If dust coats the inside, wipe it with a dry cloth.
If you choose to wash it:
Remove the bin from the vacuum body.
Rinse with plain water only.
No soap.
Let it dry for a full day.
Never install a wet bin.
Step Two: Clean the Filter
The filter is the most common cause of power loss on the V11.
Remove the filter from the top of the vacuum by twisting it.
Tap it gently over a trash can to knock off loose dust.
Rinse the filter under cold running water.
Squeeze gently and rotate as you rinse.
Keep rinsing until the water runs clear.
No soap.
No cleaner.
No brush.
Shake off excess water.
Set the filter in a warm dry place.
Let it dry for at least twenty four hours.
If it feels cool or damp, wait longer.
A wet filter can damage the motor.
Step Three: Remove the Cleaner Head
Press the red release button where the head meets the wand.
Pull the cleaner head off.
Lay it flat with the base facing up.
This is where most hair problems live.
Cleaning Hair From the Brush Roll
Flip the head over.
Pull loose hair off by hand.
For tight wrap, use scissors.
Cut along the groove in the brush bar.
Do not cut the bristles.
Pull hair free in strips.
Keep going until the brush feels smooth.
Removing the Brush Roll
The V11 cleaner head allows brush removal.
Look for the lock dial on the side of the head.
Turn it with a coin.
Slide the brush roll out.
This lets you clean the ends and the inside of the head.
Cleaning the Brush Roll
Hair often hides near the end caps.
Pull it free.
If dust coats the brush, wipe it with a dry cloth.
If you rinse it, use cold water only.
Let it dry a full day.
Never install a wet brush roll.
Cleaning Inside the Head
With the brush removed, look inside the head shell.
Dust and grit often pack along the air channel.
Pull debris out by hand.
Wipe with a dry cloth.
Do not wash the head shell with water.
Water can stay trapped inside.
Clear the Wheels
Spin each wheel.
If a wheel sticks, hair may be wrapped around the axle.
Pull hair free.
Cut carefully if needed.
Free wheels help the head glide and reduce strain.
Step Four: Check the Wand
Remove the wand from the vacuum.
Hold it up to a light.
If you cannot see through it, there is a blockage.
Push the blockage out with a long stick or broom handle.
Never use sharp tools.
Step Five: Check the Air Intake
Look at the port where the wand connects to the motor.
Small debris can lodge here.
Pull out anything you see.
Even small clogs matter on the V11.
Step Six: Reassemble the Vacuum
Slide the dry brush roll back into the head.
Lock it in place.
Spin it by hand to check for drag.
Reattach the cleaner head.
Reattach the wand.
Install the fully dry filter.
Make sure all parts click firmly into place.
Test After Cleaning
Turn the vacuum on.
Listen to the sound.
It should sound smooth, not strained.
Test on carpet.
The brush should spin strong.
Test on hard floors.
The vacuum should glide and pull fine dust with ease.
Run time should feel longer.
Common Mistakes to Avoid
Putting the filter back while damp.
Using soap on the filter.
Forcing stuck parts.
Letting hair pack past the bin line.
Ignoring the head and wheels.
Why the V11 Pulses When Dirty
The V11 protects its motor.
When airflow drops, it pulses to cool down.
This almost always points to a dirty filter or blockage.
Cleaning restores airflow and stops the pulsing.
Extra Tips to Keep the V11 Strong
Use medium power for daily clean.
Save boost mode for rugs and heavy soil.
Empty the bin often.
Wash the filter once a month.
Check the head after heavy hair jobs.
When Cleaning Is Not Enough
If run time stays short after cleaning, the battery may be worn.
If the brush will not spin, the belt may be damaged.
If the vacuum shuts off even with clean airflow, the motor may be overheating.
These issues go beyond routine care.
A Clean V11 Feels Like a New Vacuum
After a full clean, most owners notice the change right away.
The pull feels stronger.
The push feels lighter.
The sound feels smoother.
Cleaning a Dyson V11 does not take long. Most of the time is waiting for the filter to dry.
That wait pays off with better power, longer run time, and a vacuum that keeps pace with your home instead of slowing you down.
