How to Identify and Fix Common Vacuum Problems ?

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

Blockage – when a vacuum cleaner becomes unusually loud, it is normally because of a blockage of some sort. This is a problem that is easily solved by turning off the cleaner, check for blockages in the pipes, and remove them. You can also check and empty the canister to remove any possible blockages there as well.
If your vacuum cleaner has lost suction power, it`s time to empty the container. Vacuum cleaners come with various foam or mesh filters. These might get clogged over time if not cleaned or replaced properly. This will cause your vacuum to lose suction.
What should I do? If your vacuum cleaner whistles, this is usually a sign that your device can`t suck in sufficient air. Often, it`s the dust container or bag that`s full. Check these first and exchange them if necessary.
Issue with Pump or Filter

If your washing machine makes a loud rumbling or repetitive banging sound, which is particularly bad on a spin cycle, then it is most likely due to loose or worn out drum bearings. It is best to consult an expert on this particular issue, rather than attempt a DIY fix.

The most common problems found in vacuum cleaners are low suction force, excessive noise, burning smell, vacuum not turn on, and overheating. These issues can be fixed by either cleaning the device or replacing some parts of the device. At times, it is best to seek a professional to fix the cleaner effectively.
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.

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.
First, How long should you expect a vacuum cleaner to last? On average, According to Consumer Reports, vacuum cleaners last a median of eight years. But the lifespan varies wildly by not only brand but your own personal use. This should be expected.
If you listen very carefully, sometimes you can hear a “hiss” sound that is the signal of a vacuum leak. However, the most common way to notice this is when the engine loses fuel efficiency. The reason for this is due to the fact that vehicle exhaust is delayed on exiting the combustion chamber.
During the propagation of sound, the particles of the medium receive these vibrations and transfer them to the surrounding particles, allowing sound to travel. So what does happen to Sound in a Vacuum? In a vacuum, there are no (or very few) particles that can transfer and carry vibrations, so the sound cannot travel.
If your ball bearings are starting to falter, you may notice the following: Your washing machine will sound like an actual jet or you`ll hear a tell-tale metal-on-metal clunking. Water or oil will start to leak from under the unit. You`ll get an overloaded error message from the washer dashboard.
The most likely reason for a washer making noise during the spin cycle is an item caught in the lint trap, seal or between the drum and washer casing. This causes a rattling or banging sound, which can be extremely loud.
As a general rule, if the repair is going to cost less than half the cost of a new vacuum cleaner, it`s best to go ahead and get it repaired. When the service tops half the price of a new machine, it`s probably best to invest in a newer model.
If your vacuum is fairly new and this is the first time you`re experiencing a problem, repairs are probably the best option. In fact, your vacuum may still be covered under warranty. However, if you`ve had to pay for multiple repairs and you`ve had the appliance for many years, it might be time for a new one.
With the exception of top-of-the-line brands, most vacuum cleaners have a lifespan of about four to six years. While not all machines will need to be replaced after four years, it`s a good indication of when you may need to think about investing in a new one.
Signs of Vacuum Pump Leaks

Oil from the exhaust port running down the pump. Rumbling sounds coming from the pump. Repeated failure to reach maximum pressure for tasks. Mist or smoke coming from the exhaust section of the pump.

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.
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.

Check the filter: A clogged filter can also cause the vacuum to blow air instead of sucking. Check the filter and clean or replace it if necessary.
Again, due to the small particle size of baking soda or freshener product, these can clog the pores of your vacuum`s bag or HEPA filter. Or it can “cement” debris into the cyclones of your bagless vac! This can drastically reduce suction resulting in poor cleaning performance and cause clogs to form.
Home experts recommend that carpets and rugs be vacuumed at least twice a week, and more often in high-traffic areas. If pets are in the home, daily vacuum cleaning is strongly recommended to remove dirt, hair, dander, and the smaller microscopic allergens that are invisible to the naked eye.
Your vacuum cleaner will stay in excellent working condition if you have it serviced regularly. A regular service will also help the motor to last longer and prevent it from breaking down prematurely.
A rattling sound inside a pump may be caused by damaging cavitation, resulting from imploding internal gaseous bubbles due to restricted flow, improper pressure, or other issues. Likewise, water hammering, a single implosion of a large gaseous bubble or air pocket might sound like a loud bang.

the most relevant questions and answers related to your specific issue

The vacuum is making a noise like something is stuck when it is in the carpet position but not when in the floor position. I can’t find anything that is stuck in the areas that I can see. I have cleaned the brush but it does not seem to want to turn. Does this machine need to be oiled so the roller will turn? Is there a way to check inside the motor? Do you think that because the brush won’t turn that is making the noise? Do you know of any repair shops in the Lake Havasu City, Arizona area?
ANSWER : As far as the roller brush goes, yes, it does need to be cleaned. Follow the directions to remove it and clean as best you can of all debris. On both ends of the roller brush there will be two “holders” of sort that connect the brush to the frame of the vacuum. These need to be able to turn freely around the brush. Clean them as best you can and spray some WD40 in between the roller and both the holders. Work the holders around by hand to be sure they move freely..I would also check to see if your belts are snug..

I cleaned out my dyson ball as it smelt when i hoovered, cleaned filters, washed out canister and took the screws out of the front bar so i could clean near the brushes.. now its making a high pitched noise and when i switch it off it makes a noise like an engine shutting down! Have i disturbed the motor?
ANSWER : Hi its Darran at Dyson.

The screws on the base of the cleaner head should not have to be removed to access the brush bar so it is possible that the brush bar has come out of alignment, hence the noise the machnie is making.

Please ensure that the soleplate has been correctly positioned and that the brush bar is aligned correctly before attempting to use the machine.

If this does not resolve the problem, please contact our Helpline on 0800 298 0298 (UK) or 1866MYDYSON (US).

Kind regards

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.

No suction I cleaned and checked all hoses, sounds like something is stuck inside, like a sock, took machine apart as much as I could and couldn’t find anything. Any suggestions?
ANSWER : Ok first thing to do is remove & clean the 2 piece premotor filter or purchase new.

Now remove soleplate from bottom of machine to do this rotate the 3 plastic screws to unlock position. Lift sole plate off now remove any blockagers or fluff that may be built up over the brush roller.
Remove hair from brush roll using scissors.

Check short clear hose for blockages & any damage rips or tares if it is damaged purchase new hose.

Now look at belts & rotate brush roller it should turn relatively easy if it is difficult to turn by hand remove the brush roller & pull off the end caps the axle will come out with one of the caps.
Check the roller bearings clean away dust build up replace end caps & axle spin roller holding on to end cap if freely to spin refit back on to machine.

If its stiff to rotate you will need new roller.

Now pull off the 2 inspection ports check them for bits of paper etc especialy the (U) shaped port at bottom rear of machine this can contain pens pencills stones all sorts of items that hinder the suction.

Now check the long flexi hose & metal wand for any obstructions.

If after all this machine is still not working correctly go to this site http://dysonmanuals.llc.nu/

On this site you will find Dyson service manuals covering poor suction, clutch,motor, etc.

High pitch My Hoover fusion vacuum cleaner began making a high pitch sound that makes it very annoying to vacuum. I cleaned all the things I could clean. I even cut out all the hair that was entangled in the brushes. Any idea what is causing the sound. It sounds like an siren is going off.
ANSWER : The Hoover Fusion has design flaws in the motor, including a metal plate that is too thin to contain the forces acting on the motor, particularly the constant strong tension from the drive belt, and a plastic plate that is attached to the metal plate by two screws that gradually loosen over time. Assuming the filters and canister are clean, a high-pitched noise coming from the motor indicates it is about to fail as a result of these problems. You can replace the motor after it fails, but the problem will eventually occur again. For those very mechanically inclined, when the motor first starts making the high-pitched noise, you can dismantle it and tighten all screws.
