How to Identify and Fix Common Vacuum Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :

If you are still having problems with the suction on your Dyson vacuum after cleaning the filters then make sure the bin is empty remove your filters and quickly test the suction from the handle it should take no more than 5 seconds of running to do this. Removing the filters rules out any problems with the filters.
A clog is a common (perhaps the most common) reason that a Dyson unit loses suction. They have a number of choke points in the airflow paths. Some considerations follow: Hoses: because of their often rough inner surfaces and inevitable bends, hoses are prime locations for clogs.
Check both ends of the tube for any debris that may clog the machine. Make sure to empty dirt bin and clean the filters if they are dirty. If you experience no suction when using a tool, remove the tool and check each opening for clogging.
“The machine is designed to pulsate. This is an audible feature that indicates a restriction of airflow and prevents damage to the motor. This is usually caused by a blockage within the machine or a clogged filter. When the machine is pulsating, it will switch on and off in quick succession.
There are a number of possible causes of the pulsing in a Dyson vacuum – a malfunctioning power cord, battery or charger, clogged filter, damaged motor, or obstructed hose or wand. It`s important to troubleshoot all the possible causes of pulsing in your Dyson vacuum cleaner.
If the machine will no longer efficiently pick items up, the filter might be dirty. If after cleaning the filter your vacuum is still not sucking things up, turn your vacuum around and pull the red tab at the bottom of your Dyson out.
Boil old suction cups to revive them.

Take the pot off of heat and drop your suction cups in for about 30 seconds. Take them out with a pair of tongs and pat them dry on a lint-free towel. Try to use the suction cups right after you dry so they`re still warm and flexible.

Gravity and friction are the two main forces that make vacuum suction work. While gravity pulls molecules in the air toward the earth, creating an atmospheric pressure, the suction cup and vacuum pump cause a pressure difference, attaching both surfaces.
To reset the Brush bar press the Brush bar control button twice or switch the machine off and back on.
One of the first things to do when your Dyson vacuum cleaner keeps starting and stopping is to empty the bin. It may be full, or the machine may simply perceive it as too full to continue working. Dyson vacuum cleaners require constant airflow through them to work, and a full bin can stop this from happening.
It`s possible there`s a power consumption issue, with there just not being enough residual charge to run the machine. A new battery should fix this. My other thought is that it`s overheating. If too much power is pushed through the motor, which MAX power does, it could stop after a few seconds if it become hot.
If your Dyson vacuum cleaner is making a loud vibrating or revving noise. First thing to try is empty your bin and make sure there are no blockages, if that doesn`t solve it then remove the brushbar and then try switching your Dyson back on again.
A Dyson vacuum cleaner has a lifespan of around 10 years. This is considerably longer than most other vacuums. So, if you`re looking for a high-quality vacuum cleaner that will last you for a long time, a Dyson could be a good choice.
Summary. Dyson batteries should last around 2-6 years before needing to be replaced. This wide range reflects the fact that how you care for and maintain the battery will affect how long it lasts. If you want your vacuum`s battery to last longer, make sure it`s stored at room temperature.
The vibrating of the cleaner`s body – noise happens as air moves around inside the machine and hits various parts of the cleaner. This creates vibrations, which are the sounds you can hear. Many cleaners are made with plastic bodies, which make loud noises when they vibrate.
The suction power is to be measured at the end of the tube of a complete vacuum cleaner (i.e. with tube, hose and filters – but without nozzle). Some manufacturers show the results from measurements made at the suction of the actual vacuum cleaner.
It is obtained by measuring how many inches up a tube the vacuum motor`s intake can pull up, or lift, the water. For the Water Lift test, there is no air moving through the motor. It is a sealed suction measurement to find the pure suction force of the motor.
All vacuum cleaners operate based on air flowing from the opening at the cleaning head or tool, through the vacuum cleaner and the bag and/or filter system and then out the exhaust port. This airflow is created by the vacuum motor, which also may be referred to as the suction motor.
Suction is the air pressure differential between areas. Removing air from a space results in a pressure differential. Suction pressure is therefore limited by external air pressure. Even a perfect vacuum cannot suck with more pressure than is available in the surrounding environment.
Suction pressure is the negative difference in pressure between two places that drags liquid or gas from a higher pressure state to a lower pressure state. The suctional force in plants is caused by transpiration. This force aids the plant in obtaining essential minerals from the soil.
Description. This genuine Dyson vacuum part is the reset switch for the Dyson DC24 and D25 uprights. This switch needs to be activated if you experience a power surge while vacuuming, and your vacuum turns off as a result.
The suction control slider is located at the front of the cleaner head. The ball located between the bin and the cleaner head.

My dyson seems to have lost its suction therefore is not picking up anything yet i have found that when my dyson is standing upright it has a little more suction but nothing like how it use to work. This has only happend in the last 2 weeks. I sanded a floor & though the sander picked up majority of the dust i did use the dyson to pick up the excess and it is since then that my dyson has not been working to its full potential.

Poor Suction Heya! So I just picked up a used Dyson, but when I vacuum with it, the suction is pretty weak and it spits all kinds of stuff out the back and into my feet. When I pull the hose I have good suction, but in regular mode it hardly picks up anything. The brushes are spinning, and it eventually will clean an area if I go over it again and again. Maybe a clog somewhere? Please tell me that Dysons have better suction than my $50 Dirt Devil! Thanks!
ANSWER : I recently bought a second hand Dyson DC07. Its suction was poor. I removed all the un-clipable pipe bits and to remove any blockage but it all looked clear. The Final Sponge and hepper filter did have a lot of dust in it and the rotating brush was full of hair but nothing bad.
.
.I eventual gave in to curiosity and removed the three screws in the top or the yellow removable dust collection tube and cyclone bit to see what was in there. The mechanism to release the flap at the bottom of the collection tube does not allow you to remove the lid completely but it does open far enough to get inside. I found the whole top section of the yellow plastic bit blocked by a big plug of compacted dust and a champagne cork. If you are willing to take the risk and have a torx 15 screwdriver handy it that part may be blocked. It did get a bit messy.
.
.If I was going to attempt the same procedure I’d remove the dust collection unit from the vacuum cleaner as I did before, but leave the clear tube attached and the emptying flap firmly closed to reduce the mess from the dust falling out the bottom while cleaning the top part.

Kenmoore Intellivac w direct drive suddenly started making internal sound like something was stuck. Hose is clear, and sound is made when hose is detached from main unit. Vacuum sounds find at lower pressure, only makes sound with bag door closed and/or placing my hand over the end of hose.
ANSWER : Shut off the vac and open container and remove the bag. Try dropping a coin into the hose, then raise up to see if it falls thru to the bag area. If it does check the throat of the vac where the dirt is sucked upward to dump into the bag itself.

Dyson dc11 makes a groaning sound and no suction
ANSWER : It is more than likely that you’ve caused blockage in your turbines. Plaster dust is very very fine and will have passed through your filter quite easily. It’s also more than likely that the plaster dust has affected your motor.
.
.If you turn it on and you hear popping, then motor is more than likely deceased. If you hear something like a valve releasing when you turn the machine off then there may be a blockage.
.
.Probably best to refer to your local Dyson via www.dyson.com

My Dyson DC14 Animal doesn’t have the suction it used to. The piece in the back on the bottom – a flap it appears – stays open now, causing the machine to make a louder noise than usual. At first, if I put my hand on the flap opening it would close, allowing for normal suction. Now, it stays “open” permanently”, causing the loss of suction.
ANSWER : Hi its Darran at Dyson.

My dyson slim dc18 has suction in hose attachment but no suction in floor attachment. Tried to clear any obstruction by running clothes hanger in rectangular opening that empties into cannister and also tried to blow air through there also but still can not get suction
ANSWER : Hi its Darran at Dyson.

It would be worth checking that the brush bar is turning when the machine is in the vacuuming position. If it is not turning, please press the re-set switch located on the cleanerhead.

If this starts the brush bar turning but does not solve the problem, please check the cleanerhead for blockages and remobve any threads or hair trapped around the brush bar.

Shoudl you need any further help or advice, please contact our Helpline on 1866MYDYSON.

My dyson ball has no suction … i turn it on and sounds normal for a few seconds then it sounds like it clogs then no suction but i checked the tubes theres nothing there…
ANSWER : Take off the dust collector , put the machine somehwere out in the open air and switch it on if the motor runs up to speed then the probelm is inside the dust collector and it is probably a blocked hepa filter
.
.If the motor does not run clean with the dust collector removed then you need to remove the base plate and check for blockages there

There is a rubber valve on the top of Dyson DC14 all floors. When the vacum is locked in its upright position or the hand wand is used there is a whistling sound coming out of the valve. When the vac is used as a floor vac, it does not make the sound. Is this something that I can fix? Is there an obstruction somewhere that would be causing this sound? thank you.
ANSWER : The Fixya user in this repair is giving out personal contact information rather then helping the customer out on the Fixya board. This defeats the whole purpose of Fixya if the “TheDysonTeam” just gives out his phone number and helps the customer over the phone where the repair advice he gives can not be seen by anyone else on fixya. I was also under the impression that giving personal contact information on repairs is strictly prohibited.
