How to Identify and Fix Common Vacuum Problems ?

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

Loose connections will cause your vacuum cleaner to lose suction. Make sure that the dust container, the hose, the tube and the brush are all attached properly. If the problem continues, your vacuum cleaner might have a technical problem. If you suspect this to be the case, contact an authorised service agent.
Vacuum cleaners use an electric motor that spins a fan, sucking in air – and any small particles caught up in it – and pushing it out the other side, into a bag or a canister, to create the negative pressure.
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.
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.
Low compression, an intake leak or tight valves also can cause low vacuum at idle. If the vacuum reading fluctuates within the normal range-the gauge needle bounces around a lot-uneven compression (broken rings or leaking valves or head gasket in one or two cylinders) is a likely culprit.
In some instances, vacuum delivery may cause brain damage. Excessive force and pressure from the suction cup of the vacuum extractor can cause injury to the brain. Severe injury and bleeding may, in turn, lead to brain damage.
check for leaks or kinks in the tubing. ensure the filter is not wet (keep a backup filter with your supplies) ensure the float shut-off is not activated (if this is part of your suction machine) check for canister leaks and cracks.
What is a Good Suction Power for a Vacuum Cleaner? An upright cordless vacuum cleaner should have at least 100 air watts to effectively clean a variety of floor surfaces, with the best Samsung vacuum cleaner reaching up to 210W*.
Suction Power

The suction capacity indicates how powerful the vacuum cleaner is, and the air volume indicates how much air the vacuum cleaner is able to move. The suction power adds up the suction capacity and the air volume and indicates how much power the vacuum cleaner has.

The type of dust collector or vacuum cleaner bag and the size of it affect the suction power of a vacuum. When a vacuum cleaner bag has an extra filter, the vacuum needs a higher suction power. That way, the air will flow outwards through all the filters.
Suction lift in a pump refers to the pressure (negative pressure) on the suction side of the pump. The pressure can be measured from the centre line of the hydraulic part of the pump down to the water surface on the suction side of the pump.
Even in a vacuum there remains some pressure… it is simply a pressure at a magnitude below the surrounding atmospheric pressure. Vacuum does not necessarily mean the absence of all pressure; vacuum can be any pressure between 0 PSIA and 14.7 PSIA.
The maximum change in pressure produced by a vacuum pump is limited; it can never be higher than atmospheric pressure. Plus, as vacuum increases, the volume of air passing through the pump drops continuously.
Low compression, an intake leak or tight valves also can cause low vacuum at idle. If the vacuum reading fluctuates within the normal range-the gauge needle bounces around a lot-uneven compression (broken rings or leaking valves or head gasket in one or two cylinders) is a likely culprit.
Vacuum means the absence of all matter including air. As there is no air in the vacuum, air pressure will be zero.
Check that the vacuum cleaner is plugged into a working power outlet and that fuses and breakers don`t need resetting. An activated thermal cut-out due to a blockage is the next most likely cause of the problem. Check for blockages in the hose and filters, and remove any obstructions that you find.

Suction vacuum one day fine next not having great suction picking up big things but not feeling that deep down suction rolling too too easy changed bag, belt and cleaned roller it is like it is gliding over but not really getting deep visible cannot even tell I went over carpet
ANSWER : Don’t panic! Easy fix!
.
.I was having the same problem, but I removed the base plate from the bottom of the vaccum (5 screws on mine), revealing the roller and the engine. Just behind the roller is an intake tube. Mine had a piece of wrapping paper stuck in it causing everything else to clog up.

My Dyson Animal has good suction and works fine for actually picking up dirt, but when I use the vacuum with the roller, I hear a grinding/rumbling noise. Its only when I use the vacuum with the brush rotating. It does not happen hen I shut the roller brush off. The belt is fine. I cannot figure out what is wrong as there are no clogs, debris, or foreign objects stuck in the brush or in the belt. The noise seems to be the only issue. The vacuum picks up fine. It just doesn’t sound right a
ANSWER : Trace the path of the suction into the tank and see if there is anything loose or ingested..Also, remove the brush and clean as best you can. Perhaps there is something caught in it. Lubricate where it makes sense with some WD40.

The original belt on my upright Kenmore Progressive broke and I replaced it with the spare that was in the vacuum. The vacuum and spare belt are about 10 years old. Then the spare broke after one vacuuming session and there was a burning smell coming from the vacuum. I ordered new belts and replaced it with the new belt. It seems to be working fine with no smell. I checked the belt after I vacuumed the family room and although it was in tact, the belt was very hot. Is that normal? Should t
ANSWER : The belt heats up due to the friction, as well as being in contact with the shaft of a hot motor. It is normal.

My filter queen just had the motor rebuilt last year and was basically a brand new unit when I got it back. It is not picking anything up now when I vacuum. The beater bar on the carpet attachment is turning fine and when I take all the attachments off the hose I can feel the suction being created like it should be picking up debris just fine. I have emptied the canister even when it did not have much in it; however, it still will not pick anything up off the carpet. It picks up debris tempo
ANSWER : It sounds as if you have a clog inside the “Power Nozzel”. They mention that there are “no user serviceable parts within the Majestic® Power Nozzle” My advice would be to see if you can see a clog with in reachable distance and try to remove the clog. One way to check for a clog which may work for you is to remove the attachment and shine a flashlight on one of of the attachment and look through the other side and see if you see light, if no light, most likely a clog. Past that you might void the warrenty if you try and open it up the Power Nozzel itself. You may want to ask a Phone service rep about clog removal.

I purchased a brand new Eureka Pet vacuum, sorry don’t know exact name but it the one that has the self cleaning duster on it. Last night I used the vacuum on my carpet, it was working fine until I accidently sucked up the corner of a scarf that was hanging off a couch. I shut the vacuum off, pulled out the scarf and and resumed vacuuming. Much to my dismay the suction on the vacuum had ceased. Can you tell me if there is a reset button on the vacuum? The vacuum does not appear to be damage
ANSWER : If the motor is running, there should be suction. Possible problems depend on whether it’s a canister or upright and are:
.A clog in the hose, UR or canister. Detach hose. Drop small coin in one end and lift hose causing it to roll out the other. If it does, no clog in hose. Drop same coin into hose opening on power head. If it rolls out, no clog in PN.
.Broken fan blades, UR. Needs to be taken to shop for repair/replacement.
.
.A reset button is for use if the motor isn’t running, so won’t have anything to do with the suction.

My electrolux oxygen cannister has the “bag change” light on when there is a new bag. The light stays on when the suction power is high (to pick up small particles) and it won’t pick up, but the ight goes off when the suction power is low (to pick up big objects). I changed the hepa filter, cleaned the motor filter and changed bags, but all that didn’t help.
ANSWER : You may have a clog in the hose, and/or the inlet by the brush roll. A clog will turn on that light as well as a full bag.

Hoover WindTunnel Self-Propelled V Belt
ANSWER : I had this same problem with the V belt on my Hoover Vaccuum..
.There are three (3) basic things that will cause the brush roll not to spin..
.1. When handle is upright, brush roll is OFF..2. When switch is set for HARD surface, brush roll is OFF..3. Broken/worn FLAT belt or V Belt, brush roll will not spin.
.
.I noticed that the brush roll was not spinning when my vacuum was set for CARPET. After removing the cover I noticed that the V belt was loose, I thought the belt was worn so I purchased a correct replacement belt and installed it, but the new belt was also loose and when I turned the large flat belt pulley it did not turn the V belt pulley at the same time..
.I double checked the surface setting and I had the vacuum switch set for carpet, but still when I released the handle out of the upright position the brush roll would still not spin..
.My aggravation finally led me to this posting on FixYa’s website..
.The first thing I did was checked the screw to the left of the V belt as suggested by ejmjr5 and this did nothing to solve the problem or create more tension on the V belt, even when the upright handle was not in the upright position..
.After playing around with the surface setting control switch/nob I notice that when I moved the switch out of the HARD surface setting and over to CARPET, I had thought that the switch was set for CARPET as it visually appeared, but I was not pushing the switch over hard enough to click it into the CARPET setting mode..
.VOILA, the brush roll now spins correctly even though the V belt seams to be too loose for the pulley..
.You really have to force the switch into the CARPET setting. Be sure that you hear the switch/nob click into place..
.Now you can effectively clean up after that hangover of a party!.
.Burp!

Dirt devil vacuum cleaner–trouble vacuuming dirt and pet hair on carpeting –is the problem with the spinning brush which contacts the floor,  not contacting the carpeting??  I thought (when I bought this vacuum) that the aforementioned brush was adjustable to various heights of carpeting.  Sometimes, it seems like nothing is being vacuumed up –unless I have just put a new bag on the vacuum… Do I need or can I replace the spinning brush on the bottom of the vacuum so it kicks up and vacuums
ANSWER : Try replacing the belt. Rubber belts stretch out after about a year.
