How to Identify and Fix Common Vacuum Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :
Empty your dust bin
An overflowing or packed dust bin may lead to a shrill noise as the vacuum can`t fit any more debris inside. Check your dust container and make sure it is entirely empty.
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.
With excessive use and regular exposure to dust and dirt, the filters attached to the vacuum cleaner get grime on them. This dusty layer closes the way for air to pass through the channel. Thus, the machine puts a lot of effort and generates noise in excess to pass the air throughout the system.
Low suction or poor pick-up may be due to a clog in the vacuum cleaner. If you notice a change in the sound of the motor or a reduction in the spinning action, check for clogs. First, remove the Easy Empty dirt tank from the vacuum and discard all dirt and debris.
It`s caused by a worn-out motor belt. The burning smell can also be as a result of the rubber belt burning due to the loss of elasticity. All in all, the belt is worn out and needs replacement. To fix the burning smell problem in a vacuum cleaner, you will have to replace the motor belt.
However, the noise levels of vacuum cleaners fall between 75dB to 85dB. Thus, continuous exposure to such noise levels affect a user`s health while also being a sign and source of inefficiencies in the equipment.
Sound enclosures, noise reduction blankets, sound curtain noise barriers, or sound barrier walls are a few options to consider when reviewing noise reduction materials. If the vacuum pump is indoors, a noise enclosure would be the recommended solution.
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.
A strong odor from the shellac that coats the copper coil windings is an indicator that the motor is about to or has burnt out. If the motor is still running, even if it turns on and off by itself as it is heating and cooling, you can still run the motor until it gives up for good.
If the filter bag or canister is too full, it cannot pick up any additional particles and will simply jam or the motor will overheat and shut down. So, when you suspect your unit is about 75 per cent full, empty it!
Fine particles. Fine particles are no match for even the strongest vacuums. Construction dust, makeup, used coffee grounds, fireplace ash, and other fine particles can burn out the motor and be released back into the air. It`s best to sweep these items up to keep your vacuum – and yourself – safe.
According to the U.S. Consumer Product Safety Commission, certain models of the Bissell Multi-Surface Wet Dry Vacuum are being recalled because the battery pack can overheat, start smoking, and poses a fire hazard.
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.
Your Vacuum Pump Is Noisy
Sometimes, extra noise can mean that there are pieces of debris stuck in the system rattling around. It can be an easy fix—just locate and remove the debris. A loud pump could also mean you have worn bearings that need to be replaced or lubricated.
Upright vacuum cleaners typically have a noise output of 75db to 80dB. They are often the loudest vacuum cleaners due to their powerful suction and motor size. Cylinder vacuum cleaners are a bit quieter than uprights on average, with a range of approximately 72dB to 80dB.
Vacuum cleaners that produce less than 60dB of noise are called silent. That doesn`t mean that they don`t make any noise, but you can still hear the TV or easily song along to the radio. Vacuum cleaners with a noise level between 71 and 75dB are loud.
ASHRAE recommends evacuation to below 1000 microns for moisture removal and below 500 microns after replacing a compressor. Some equipment manufacturers call for evacuation to 400 microns to ensure that harmful water vapor is removed from the system.
There`s a reason your vacuum, car, potato chips, are way louder than they need to be. Surprisingly it`s done on purpose. Engineers and designers manipulate the auditory element of products. Some of the biggest culprits are vacuums and cars.
Vacuum noise is quantum noise related to the zero-point fluctuations of the electric field in the vacuum state. Such fluctuations exist even though the vacuum state has a photon number of zero. Figure 1: When a beam splitter is used to attenuate a beam, vacuum noise enters via the open port.
There are varying degrees of quality and value when it comes to vacuums; if you paid a lot for the appliance, repairs are likely worth it, but we recommend that you don`t spend more than half of the original price for any repairs.
The average life expectancy of a mid-range vacuum cleaner is about six years. You can fix or replace things like blocked filters, jammed brush rolls, frayed hoses, worn-out stick vac batteries and broken accessories yourself.
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 best vacuum ever constructed on Earth was done at CERN at reported to achieve a density of about 1000 atoms per cubic centimeter. While this is astonishingly low, it is still over 2 million times more dense than interstellar space!

Bearing screeching? when turned on the hoover will work normally but will give off a high pitched squeling noise which comes and goes. when it is turned off and the motor slows, the squealing also lessens in comparison to the revs.
ANSWER : Hello,
Yes, it could be a motor bearing. Another possibility is the fan could be broken. Remove the bottom plate from vacuum. Spin the belt motor pulley slowly and view the fan. You may have a plastic fan .\011\011\011that has broken or something is keeping the fan from spinning. Here are links with illustrations to an online guide. (the links will say “belts” but it will show how to get to the fan). Click the one that best matches your vacuum.
Hope this helps.

I have a new Hoover BH50015 hand vac. The noise is terrible. It sounds like the bearing are bad. When you take off the cup and the filter and listen to the motor as it slows down after turning it off it definitely sounds like bad motor bearings. Hoover tells me the loud noise is normal. Can you help?
ANSWER : Yes the bearing is full of dust and dirt
.unscrew the housing and clean the bearing area and shaft
.then add a dap of Vaseline to the shaft and reassemble
.The shaft rides on a nylon bushing which acts like a bearing but has no ball bearings in it
.regreasing it is the only help you have for this one here

My 4 yr old Nilfisk vacuum cleaner has been working fine up until now. But suddenly, it has hardly any suction power and also, hot air seems to be coming out thru the vents on top and also thru the space that’s normally used for blowing air OUT….the outlet with the retractable cover located close to the part where the power cable comes out of and retracts into. I’ve checked the filter and the hose and they are not clogged…I have also put in a new bag. Not keen to buy another vacuum cleaner u
ANSWER : Hi there SmartAlec from Nelsonvacuums.com.au here.It sounds like a blockage of some kind. The best way to find it is to set the machine up for normal vacuuming and remove one component at a time until the suction returns. eg turn on and feel suction under floor head – not good? then remove the rod, then the hose.
Once at the machine on its own it gets a little triky as i don’t know which model you have. However if you have a bagged model remove all the filters and the bag and retest. There will be at least 2 filters, one before the motor and one after (maybe under the vacuum or right at the back). If it is a bagless model even though the filter may look clean it is probably blocked with very fine dust. If suction returns when the filter is removed then you need to buy a new filter. I am a nilfisk vacuum cleaner agent so i can supply a filter for you.
If this still doesnt help you are welcome to call me if you live in australia my contact details are on my website www.nelsonvacuums.com.au.
Hope this helps !.
Happy vacuuming 🙂

Infinity Vaccum by Shark, model number NV31COS, will not start. The vacuum was running just fine until it grabbed the edge of a curtain. Turned it off to release the suction. Turned it back on and was working fine. About a minute later the vacuum was making an odd noise. Every 2 seconds or so it would “heave” (lack of a better word) then go away, then come back and so on. Turned the vacuum off and checked for blockage, none that could be seen or felt, and now the vacuum won’t turn. Any suggestio

Sewing machine Guru needed 😉
Elna Grasshopper (new to me) circa 1950
The light works, but there was no hummm when knee pedal engaged.
I have the motor out, and it is very stiff to turn. I’m at a total loss when it comes to motors and electricity. It doesn’t smell burned, doesn’t smell at all beyond normal machine smells. (Yes, I made detailed notes and diagrams as I took said motor out!)
One other note. The long thing which my husband said might be a capacitor — it looks like
ANSWER : I just purchased a fairly tidy Elna ‘Grasshopper’ sewing machine (1951) with the same leaking capacitor problem. I carefully removed the capacitor for examination. It is actually three capacitors in one – no chance of a direct modern replacement, but anyone with those three capacitors, a couple bits of insulated wire, and a small soldering iron should be able to shoehorn them into the same space. There is a circuit diagram printed on the side of the original capacitor, showing one 0,2 micro-Farad capacitor between the two mains power buses (the two wires from the top of the original capacitor which are soldered to the top of the two outer brass bars where all the wires attach), and following on from each of those a 0,0025 micro-Farad capacitor (so, two of those), the other side of both of those joined together and going to the chassis – representing the one cable from bottom of the original capacitor, which is screwed down. Easier than it sounds – I just have to find those capacitors. They must be NON-polarised capacitors, rated for 250 Volts, and I plan to use radial (rather than axial) style, aluminium type ones – very common. From what I can gather, I believe they are needed for that lovely little motor to run properly – to have torque (‘oomph’) at start-up.....
.As to the motor not wanting to turn… difficult to say from a distance. Could it be that the ‘brushes’ are sticking – or even worn out? There are two, top and bottom, that ride on the commutator – the ring of bronze-colored squares on one end of the motor, behind the wiring. They are made of carbon, are what power the motor, and are held with hidden springs. With much use they wear down, but I would not expect them to be completely gone. The upper one is easiest to reach – there is a brass screw above it – careful the spring doesn’t get away. Only other thing would be fouling of the bushings that allow the axis of the motor to turn. A little penetrating oil could help there. The motor should turn very freely.

I have a roomba 530 pet series. It appears that the brushes aren’t turning. They are free of dirt and debris and move easily when manually turned. But, You can tell there may not be a motor turning, because the roomba is more quiet than normal when you turn it on. Also, the hair just collects along the bottom of the brush and doesn’t get pushed into the bin.
