Dyson Vaccum suction not strong enough

Vacuums\015 Dyson 23 Turbine Vaccum suction not strong enough. Even when canister emptied. Please help as people swear by Dyson, but I can’t see why with the poor suction I am getting when cleaning the house. Having to go over the same spot to **** up a piece of thread 3 times+.\015

How to Identify and Fix Common Vacuum Problems ?

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

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. Make sure there`s no dirt lodged in the top part of the bin.

Check for a plugged hose:

Plugged vacuum hoses are sometimes the reason for a loss in suction. Hoses can get clogged with hair, dust bunnies, string, or anything else that can`t pass through the other end of the hose. Airways inside the machine should be looked at as well. Wherever there is an air passage, check it.

One of the easiest ways to increase vacuum cleaner suction is to empty the dust bag or container. Dust containers need to have enough space for airflow, otherwise, they could get clogged and have less suction power. Regularly check your dust compartment and empty or change it when it`s already 70-80% full.

Which Dyson vacuum is the most powerful? In terms of sheer suction power, the Dyson Ball Animal 3 Extra is the most powerful option in Dyson`s current lineup, offering 290 AW, or air watts, of suction power. Among the brand`s cordless stick vacuums, the Dyson V15 Detect is the most powerful, with a rating of 230 AW.

The suction control slider is located at the front of the cleaner head. The ball located between the bin and the cleaner head.

Within the 3.5kg machine is 262AW suction power¹, to ensure no loss of suction. HEPA filtration traps 99.99% of particles down to 0.1 microns in size², for scientific proof of a deep clean. Our latest vacuum also includes a single-button power control – removing the need to hold a trigger as you clean.

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.

The two main indicators to determine vacuum power performance are water lift and airflow. The water lift is measured in mmH₂O, mbar or kPa. It represents the suction force and is the reference parameter for vacuuming liquids and heavy materials. The airflow is measured in m³/h or in l/s.

The suction power is measured in Watt (W) and is typically between 250 W and 450 W for machines with 1 motor. 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).

Ultimately, unlike bagged vacuum cleaners, the performance of Dyson machines won`t be compromised the more you vacuum. Our machines are engineered with six layers of advanced whole machine filtration, which means that we capture 99.97% of microns as small as 0.3 microns.

The Dyson V11`s vacuum motor is also more powerful, delivering 185 Air Watts of suction power in Boost mode, up from the V10`s 151 Air Watts of power in Max mode. With more power at the vacuum`s head and in the motor, you might think battery life would take a serious hit.

Producing up to 115 Air Watts, it generates powerful suction on carpets and hard floors.

Dyson invested £2.5 billion in research and development.

While you might feel that this is the reason their products are expensive, you`re highly mistaken. This investment was mainly to accommodate a centre for their 1,200 employees, 22 laboratories, prototyping space, and areas for collaborative work.

Dyson has only built it around 11 of its “root cyclones”, compared with 14 in the Dyson V15. This gives it a quoted maximum suction power of 150AW (Air Watts), where Dyson quotes the V15 at 240AW.

The suction power, motor, and battery are all the same. Dustbin is the same on the Absolute and Animal model and slightly smaller (at 0.54 L) on the Motorhead version. The only notable differences among each of these models are the cleaning heads and accessories included.

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.

Sometimes your vacuum pulsates on and off or keeps dying when using the extra powerful `Max Mode`, which can be related to the charge of your battery. Try turning this function off by pressing the Max button on your vacuum.

If the machine switches on and off in quick succession, while making a pulsing noise, it could be an indication to either a dirty/blocked filter or an obstruction in the machine affecting the airflow. In the event of an airways obstruction the machine is designed to pulsate.

If your vacuum cleaner keeps turning off, this could be due to the following reasons: Blockages – check the hose and head for any obstructions. Filter – always check your filters, if these are clogged this could be causing the vacuum cleaner to work harder and lose suction power.

Dyson Vaccum suction not strong enough

ANSWER : Look for an obstruction in the air passages at the bottom and where the air enters the canister. Make sure the HEPA filter is not plugged (take it out for a test). Hope this helps!

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.

No suction Just received my refurb. dyson animal bagless. Finally figured out how to get it all together, turned it on and there is no suction coming up thru the beater bar. The hair is just collecting around the bar and not going up into the canister. It appears all the suction is going thru the open red end of the attachment hose, which has a vented cover piece. Am I missing a piece or is there a switch to turn of the attachment suction?

ANSWER : So the red hose isn’t connected to a part on the vaccum so like it is connected to the connester but not to an opening just above the beater bar, this is the only idea i can supply you with. good luck, maybe i got lucky and helped you out.

Hoover Windtunnel My Hoover Windtunnel is 3 years old. It worked great until yesterday when it lost all suction. I have followed the manual to trouble shoot any possible clogs and could find none. Then I noticed that when I remove the dirt collection cup and held my hand over the vent the suction is fine and strong. So… I replaced the hepa filter thinking that might be the problem. That didnt’ work. The motor runs fine. The suction without the dirt cup inserted is strong. As soon as you insert

ANSWER : Either the hose has a clog, or the inlet down by the belt is clogged. Is there suction at the end of the hose, if not then it is clogged. If there is suction, then it has to be clogged down below by the brush roll, check that inlet. There also is a filter at the bottom where the dirt cup (and bag) is, check it also.

ANSWER : Mine does the same thing. There is no suction. I found that there is a door that opens when you tilt the handle in the down possition. I think there should be a spring in place so it can open. Until I find a replacement spring I have to open the door manually throught the opening under the light.

Hi my dyson dc18 has great suction from wand but when you got to use the vac for floors little suction but wand still got suction even while vacuming floors is it suposed to stop suction from wand

ANSWER : My Dyson dc18 had the same symptoms. The wand worked well and the floor bar had no suction. After removing pieces & shoving my fingers into the machine (no blockage) I found the suction pipe rotates between two positions (floor and wand). It looks like a piece of plastic broke on the outside housing, so it no longer rotates positions when the wheels are raised or lowered. My son found we can move the suction by sliding a finger into the mechanism behind the wheel cover, and rotating the plastic piece clock-wise or counter clock-wise until it locks into position. It’s a big pain but it works for now. I wish I could find a replacement piece online. Patty

Dyson hose suction strong…when using the brush bar no suction available. Have looked to see that all airways (u-bend) are clear. When engaging the brushbar the brushbar turns but no suction to floor.

ANSWER : Hello,

There. are several things that this could be. Probably the most common problem. that we see when customers come in with this problem is actually a .fairly simple problem to fix. Here are just a few things that this could. be.

The fist possible problem sounds like the most probable to .me, just because of the fact that you said you had just replaced the .clutch, and therefore you had to remove the bottom sole plate. This is a. VERY common problem actually.

Possible Problem #1. The first .problem is extremely common. In fact, we probably see between 2-3 of .these problems every week. It mostly happens after people take the .bottom plate off the vacuum cleaner in. order to clean the roller brush. What happens is when they reinstall .the bottom plate, they put it on on incorrectly. It’s actually very easy. to do. When the bottom plate (soleplate) is installed wrong, there will. be a gap between the bottom plate, and the agitator housing, or the .purple tray the roller brush sits in. This will cause the soleplate to .be a few inches higher off the ground then it should be, preventing the .brushes from even hitting the carpet. This makes it seem to the user .that vacuum has lost suction power because without the brushes .hitting the carpet, the machine will not pick up very well on floors, .but when they use the attachment hose there’s plenty of suction power.

Here’s. a picture of the WRONG way to install .the bottom plate. Notice the gap in between the two housings:

Here’s. another picture, that is the RIGHT way to .install the soleplate:

I. would say probably 6 times out of 10 this is the problem with the .customers machine. If you checked the soleplate and it is installed .correctly, move on to the second possible problem.

Possible .Problem # 2. Turn the vacuum cleaner .upside down so the brush roller is facing upwards. I found the easiest .way to work on it is to put it on a counter top or work bench. On the .left hand side behind the roller brush you should see a flexible .transparent hose that goes from the motor to the agitator housing. This .hose actually has a lot of strain on it when the vacuum cleaner is in the reclined .position. When the first few series of Dyson DC07 models came out, they .didn’t make this hose long enough, so when the vacuum was in the .reclined position, it would put too much stress on the hose, and cause .the hose to actually crack, usually right where the end of the hose that. goes into the agitator housing. Examine your hose and see if you have .any visible cracks in this hose. If you need to you may just remove the .entire hose assembly by pulling on it. It will easily come right out of .the machine so you can inspect it better. Here’s a picture of where the .hose usually cracks:

This. would also explain why the vacuum works fine when using the .attachments, but not on the floors. The attachment hose uses a different. suction channel, and when the machine is in the upright position, no .suction goes through this hose. If you do find a crack in this hose, the. this hose needs to be replaced. Here’s a direct link to that hose on .our GoVacuum website.
Dyson DC-07 & DC-14 Upright Replacement Internal Hose. Part # 904219

Possible Problem #3. I would suspect that this. may not be the problem, but if neither of the solutions above worked, then try this. one. Dyson’s in general are prone to clogging. There are a few clog .ports throughout the vacuum cleaner that were added there due to Dyson .prototypes becoming clogged at these points. Here are pictures of how and where to check .for these clogs. Simply remove the suction port covers at both of these .locations:

If. you are getting suction power from the hose, but the vacuum still .doesn’t pick up on the floors, I think that these solutions should fix your problem. If. you just replaced the clutch mechanism, the roller brush should be .fine, but turn the vacuum over on it’s side and make sure that the .roller brush is actually spinning while it’s on carpet mode. If none of .these problems fixed your Dyson, please use the Clarification Request, .or leave another comment here on the Fixya repair page, and I’ll be .happy to further diagnosis the vacuum cleaner with you.
