How to Identify and Fix Common Vacuum Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :
Clog located in the vacuum hose
Turn the unit on and feel the suction at the end of the hose handle. If there is no or low suction, then the clog is in the hose. You can remove the clog by running a long, stiff object through the hose, such as a butter knife, starting at the wall end.
When you vacuum water, you could damage your vacuum`s motor, risk electrocution, and make a huge mess. Unless your vacuum is a wet/dry vacuum rated for water, you should never vacuum water.
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.
You can find a vacuum leak using nothing more than water, too. When you spray water over a vacuum leak, you will hear it get sucked into the engine. It won`t affect idle much, but it can prove effective for large vacuum leaks like cracks in lines that are difficult to see. Enrich it With Propane.
Connect a tachometer and vacuum gauge to a none regulated vacuum source on the engine. Disconnect and plug fuel vapor canister vacuum lines. Start engine and run the engine until it reaches normal operating temperature. Note the vacuum gauge reading and any variations in the pointer movement at idle and 2000 RPM.
Removing a clog
Use a pair of pliers to make one end of the hanger into a hook shape. Put the end of the hook into the hole where the vacuum where the clog is located. Push the hook down until it won`t go any further. In some cases the hook will go all the way through and push the clog out the other side.
The short answer is that yes, water can exist as a solid in a vacuum.
The most common cause of loss of suction is that the filters have become blocked. They may require cleaning or replacing. Another cause could be that the vacuum cleaner hose is blocked.
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.
The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound. If you are sitting in a space ship and another space ship explodes, you would hear nothing.
Hissing or Sucking Noises
Usually, when the leak isn`t too bad, you will hear hissing noises coming from the engine. This may also sound like whining sounds or whimpering sounds. For more severe vacuum leaks, the noise is sucking or suction, much like a vacuum cleaner.
If you suspect that you have a vacuum leak in a specific area, you can use soapy water in a spray bottle to see if there is a problem. Spray soapy water on the suspect area while the car is running. If the car`s idle levels out after you spray the soapy water, then it is likely that it has temporarily blocked the leak.
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).
A total, or perfect, vacuum would be a space from which all matter has been removed. This includes solids, liquids, and gases (including air).
For centuries, physicists thought there was no limit to how fast an object could travel. But Einstein showed that the universe does, in fact, have a speed limit: the speed of light in a vacuum (that is, empty space). Nothing can travel faster than 300,000 kilometers per second (186,000 miles per second).
Use Some Water
A little bit of water can do wonders for boosting a suction cup`s grip. Using warm water, rinse the whole cup so it softens it up. Shake the drops of water off the cup quickly and then put it up on the wall. That can often do the trick.
The most common problem with a vacuum cleaner is also the easiest to remedy: clogs in the hose or attachments. Also the electrical cord, motor, switch, fan, brushes, and motor bearings can all need repair or replacement. The drive belt may need replacing; and the attachments, hoses, and filters may need unclogging.
Engine loses power or won`t start
If the pressure is too high, it can cause a head gasket to be pushed out, can cause cylinder head hardware to break or in some cases, will cause detonation inside the engine.
Large amounts of hair can quickly clog your vacuum, or else get wrapped around the brush and prevent it from working properly. Instead, grab your dustpan.
Panspermia refers to a theory in which microscopic life-forms, such as spores, can survive the vacuum of space and migrate between planets, seeding life throughout the universe. The theory is controversial, and so far no conclusive evidence has been put forth in the scientific literature to prove it is in fact true.
Like silk, cotton is delicate. It`s better to vacuum without the beater brush.
You can accomplish evaporation from a solution quickly by placing it in a side-arm flask, sealing the flask, and then applying vacuum. Under vacuum (reduced pressure) liquids vaporize and boil off at lower temperatures; effectively, the solvents come off a lot faster when under vacuum than at atmospheric pressure.
This is equivalent to a column of water 406.7 inches or 33.9 feet (approx. 10.3 m). Therefore, a total vacuum could only pump water from a depth of just under 34 feet or 10.3 meters. Actually, a total vacuum cannot be created over water.
Ice can form in a vacuum, but I still advise pulling a fast, deep vacuum. Now, keep reading to see why. The statement that is often made by techs is that pulling a vacuum “too quickly” can result in freezing the moisture inside the system and reducing evacuation speed.

Unbeknownst to me, someone took the bag out of my Kenmore Progressive vacuum and failed to replace it. I have been vacuuming without a bag for months, and today the vacuum stopped sucking. When I opened up the front to replace the bag, tons of dirt and dust came pouring out. I thoroughly cleaned the vacuum, put in a new bag, but still no sucking power. Just dust coming from the rear vents where one of the filters is. Is the vacuum ruined, or is it a simple solution of buying a new filter?
ANSWER : Sounds like you need to buy a new motor. All that grit and dust will ruin a motor and I’m surprised it lasted as long as it did.

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.

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.

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.

How to disassemble the brush to empty anything that might be stuck inside of the brush?
The motor seems to be overheating, all belts have been checked, all airways are clear and the filter is clean. The vacuum is vibrating and releasing a burning smell, but still sucking up dirt. There is nothing stuck on the outside of the brush, but is there a way to check inside of it to see if that is where a clog is occuring?

ANSWER : If there’s a burning smell and the belts are fine, the problem is going to be hot wires causing the insulation to melt, or the motor going bad. Discontinue use and have it checked at a repair shop.

Won’t start. My son was using the vacuum & Didn’t change the bag. The vacuum was making the full bag smell, but the light was’t on & it didn’t stop. I stopped him, changed the bag, checked the filter, closed the compartments & turned on the vacuum. Nothing happened. I checked to be sure that it was plugged in, that wasn’t the problem. I’ve let the vacuum “rest” for several days, It still won’t start. Any suggestions?
ANSWER : There is a reset button at the back of the powerhead. The user manual can be downloaded from the electrolux website, although I didn’t find it very useful. There was some info on how to change the powerhead drive belt.

Clogged vacuum Rather stupidly, my boyfriend 1) were vacuuming without a bag and 2) vacuumed up a big piece of cotton from a sofa cushion. And now it’s making a horrible noise and I see it vibrating where the tube connects to the machine. When you look inside there’s a white thing sticking out but it looks like it’s part of the vacuum. If it’s a clog, how do you fix it? I tried unscrewing the tray the bag sits in but it won’t budge.
ANSWER : You can start by taking off the bottom plate or top cover, which ever comes off, that is where the inlet starts going in and hopefully the clog is there. Could be in the hose also. But without the complete model number I can’t look it up to see a picture of it.
