Dyson DC22 Motorhead Canister Vacuum Bagless Cyclonic Vacuum\015 My son was using it last nite, said the vacuum was not picking anything up. I disconnected the turbine head from wand, found some blockage. Cleaned it out, put back together & still no suction. I noticed that when I took the cover off & plugged the hole where the little rubber piece was, it had perfect suction. So when I put the cover back on, no suction.\015

How to Identify and Fix Common Vacuum Problems ?

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

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.
Counter-rotating brush heads remove hair. Ideal for pet owners. Releases hair into the bin.
A Dyson Turbine head includes a turbine mechanism which uses the vacuum`s suction power the brush bar. The Motorhead is similar in overall design, but includes a separate electric motor to drive the brush bar instead of a turbine.
Vacuum cleaners are fairly simple machines. They need power to be transmitted to the vacuum to create a suction force that lifts debris. So, the usual areas that cause suction loss include the wrong height setting, stuck rollers, a faulty gasket, a broken vacuum belt, a filled bag, or a clogged hose.
The suction control slider is located at the front of the cleaner head. The ball located between the bin and the cleaner head.
Place the machine into the upright position. Attach the Mini turbine head to the hose or Wand. Pull the plunger into the out position for vacuuming carpets. For vacuuming hard floors push the plunger into the “in“ position to stop the Brush bar spinning.
The suction motor creates vacuum pressure and suction by rotating a motor fan. The impeller rotates at an incredibly high speed of about 30,000 to 35,000 RPM. A suction motor`s power is measured by multiplying the rate of air flow and the vacuum pressure, which induces air flow from the brush through the hose.
Motorhead canister vacuums have a motorized brush bar for digging dirt and pet hair out of carpets. Turbinehead canister vacuums have a turbinehead brush bar for carpets that can be switched off for hard flooring.
The type of hydropower turbine selected for a project is based on the height of standing water—referred to as “head”—and the flow, or volume of water over time, at the site.
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.
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.
Vacuum means the absence of all matter including air. As there is no air in the vacuum, air pressure will be zero.
Pneumatic cleaner head – Automatically self-adjusts to seal in suction across all floors, maximising dust removal without the hassle of switching or adjusting cleaner heads. Gets back up when knocked over – Conventional barrel vacuums can fall over.
`We do not recommend that owners expose their machines to water`. Dyson is urging customers not to clean their vacuum cleaners by leaving them in water, after a hack went viral online.
The cleaner head housing is not washable and should only be wiped over with a damp lint-free cloth. To maintain optimum performance, check and wash your brush bar regularly. Make sure your machine is disconnected from the charger and take care not to touch the trigger.
Dyson cordless vacuums

Heavy duty performance for big cleans on all floor types. Lightweight and versatile for everyday use.

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.
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 Dyson soft roller head (Fluffy) is specially made for hardwood floors and coated with antistatic carbon fiber filaments removes dirt and fine debris.
Higher heads are not only better because they generate more power, but also because the higher water pressure means you can force a higher flow rate through a smaller turbine, and because turbine cost is closely related to physical size, higher-head turbines often cost less than their low-head cousins even though they …
The pressure head is measured by the difference in elevation between the headwater and tailwater. A low head turbine has an operating head of 30m or less, a medium head turbine has an operating head of between 30 to 300m, and a high head plant has an operating head in excess of 300m.
Statement (I): The effective head of a turbo-machine is equal to: Gross head minus the head loss in penstock and the velocity head at the turbine inlet.
A high pitch whistle could indicate a seal is damaged or the machine is blocked. If the noise occurs without the Wand and Cleaner head, it is likely to be caused by either the bin or cyclone.

Miele, Flamenco II. 2 probs. 1. the head brush is not turning when I put it on the floor. If I pick it up to look inside…the brush is spinning fast..I put it down on the floor…the head does not spin at all. 2. The suction power has dropped significantly. The suction used to be so intense, the head would **** itself to my floor and hold on…now, hardly any suction at all.
ANSWER : Sounds like the belt is not on correctly on the beater brush or the belt is worned out now for the suction check filters or bags that need to be empty or clean

Turbine head brushroll doesn’t rotate and no suction
ANSWER : Have you tried washing the filters? The pre-motor filter (the one in the plastic housing) can get really clogged. Hold it up to the light, if you can’t see through, it is full of dust. You need to really scrub it with a brush to get the dust out (or buy a replacement). Just a rinse will do nothing. This is something Dyson is not telling you in the manual.

No suction I am getting no suction on my central vac at the vac. I do not believe that the piping is plugged up, the vacuum is not creating suction. What are the causes of no suction at the vacuum and how do I take the top half of the Nutone central vac off?
ANSWER : Use the guide at builtinvacuum.com/flowchrt.html to find the issue and solution. Most likely you need to test it without any filter and be sure the bottom of the unit is attached 🙂 To get access to the motors you need to unbolt the very top sides.

Suction Cover The suction cover of my Eureka Deep Steam 2575A is broken – the tabs snapped off of the cover so I am unable to screw the suction cover back on. I need to purchase a new suction cover but can’t find one anywhere. Anyone know what I can do? thanks

Lost suction my DCO7 lost suction in the hose I started taking it apart and cleaning it and looking for clogs (probably more than I should have) and when I put it back together it has awesome suction in the hose but no suction in the base. It just pulls the pine needles up (christmas tree) but they never appear in the “bag” compartment and when I look they are just all gathered in a clump in the bottom by the brush.
ANSWER : Hi.
.
.Remove the sole plate turn the 3 plastic screws to unlock & lift off.
.
.Now remove the blockages that have accumilated from the oppening of short clear hose.
.Check you can turn brush roller & check belt.
.
.Now reassemble switch on pull handle back & look under machine is brush spinning ?

Dyson vacum cleaner lost suction
got the DC14 and it doesn’t seem to have much suction in the floor head, the hose still has good suction. I have checked all the paths for blockage and there is none.
ANSWER : Hey, this is Leland with Crucial Vacuum,
.
.If your unit’s suction has decreased there could be several reasons.
.
.Firstly, the motor may be the problem. If you hear any noises while the machine is running, you should contact the original manufacturer for trouble shootingsolutions.
.
.Secondly, your vacuum may be in need of new parts. By changing either the brushroll or belts, you should be able to increase the quality of the suction.

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.
