How to Identify and Fix Common Vacuum Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :
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.
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.
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.
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.
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). Only massless particles, including photons, which make up light, can travel at that speed.
Invented by Dyson and engineered to run at speeds of up to 125,000rpm, our powerful new motors are at the core of our new technology.
Machine has a `running in` period
Tumble dryers may be noisier than usual when first switched on. Sometimes when the product is brand new or not been used for a while a `rumbling` sound may be heard for the first few minutes of operation.
Check the nozzle, the front end of the vacuum. If the nozzle is blocked, the vacuum will be loud or noisy while cleaning.
125 – 155 decibels: Like, firecrackers or fireworks, or a jet engine. 170 – 190 decibels: For example, a shot gun blast or a rocket lift off.
At the 155-160 decibel range not only will it severely to permanently damage your hearing, but it also vibrates your vision and makes it temporarily difficult to swallow.
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.
An upright vacuum cleaner should be around 100 air watts and a cylinder vacuum cleaner needs to be about 220 air watts.
Perfect vacuum is an ideal state of no particles at all. It cannot be achieved in a laboratory, although there may be small volumes which, for a brief moment, happen to have no particles of matter in them.
Speed of light in vaccum is 300000000 m/s.
Vacuum can refer to any pressure between 0 PSIA and 14.7 PSIA and consequently must be further defined. For applications concerned with measuring vacuum pressures over this full range, two different approaches are often taken. Vacuum pressure is measured relative to ambient atmospheric pressure.
The Dyson Hyperdymium™ motor spins at up to 125,000rpm to generate 100% more power than the Dyson V8™.
A Dyson Hyperdymium™ motor spins at up to 125,000rpm to generate the most powerful suction of any cordless vacuum.
Dyson just launched the 360 Vis Nav(Opens in a new window) robot vacuum in Australia, claiming it`s the most powerful robot vacuum currently available, as well as being a huge upgrade from the Dyson 360 Eye.
Some robot vacuums come with boundary strips that you can set at stairways, in front of kitchens, and in other places where you don`t want your robovac to go. Use these boundary markers around the furniture where your model is getting stuck, so it will know to avoid it.
Any noise level about 75 dB is considered to be a loud washing machine. As a comparison, 80 dB is equivalent to heavy traffic, a hoover, or a noisy restaurant.
If you hear a loud rumbling noise coming from your dryer, the blower wheel may be responsible. This component circulates air in the drum and blows it out through the rear exhaust vent. If it`s loose, off-balance, or blocked by lint or debris, the blower wheel will make a rumbling or thumping noise.
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.
Second, can you vacuum too much? Believe it or not the answer is no. Now, if you vacuumed continually 24 hours a day, yes, that would be too much. Vacuuming every day, or even a few times a day, is not going to create any long term problems.
90 decibels is a high noise level, equivalent to the noise generated by a leaf blower or the sound level of a concert. Compared to 80 dB, 90 dB is 10 times more intense and twice as loud. Whenever you are exposed to this noise level, you should wear hearing protection.

High rpm The machine runs very loud and sounds like the rpm is to high
ANSWER : These machines are noisy to begin with, but will become worse if anything is allowed to enter the fan area of the motor. I have seen debris clog the front fan and put the motor out of balance so it will really scream when it runs. This work is best left to a competent professional

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.

There seems to been a high pitched sound in the motor. I’d describe it as a ‘dry’ sound, and the high pitch of it is very loud. I want to stop vacuuming because it’s so loud. Are there any oil/greasing points/spots? If so, how do I find them?
ANSWER : High pitched noise is not good. It may indicate that a bearing is going out. I would not use Kirby as it may lead to burned motor.
If you feel that it vibrates quite a bit too – then it may be only broken fan blade.
Fan blade – you are looking ar around $40-$50 and if this is a motor bearing – $60-$80. If anyone wants to charge you more – we will repair it but you will have to pay shipping both ways (roughly another $30 both ways all together)
Ohhh yeah – try it with the hose. If no sound then brush roll bearings may be bad…
Good Luck,
Rocky

Noise My Dyson DC08 is making a loud, rough, vibration/noise that seems to be coming from the from the rotating brush housing. I replaced the old belt which was several years old and slipping. When I run the motor with the new belt removed the machine sounds normal. The bearings on the rotating brush seem to be running smoothly when turned by hand both when out of the brush holder and when installed in the machine. I can’t find anything rubbing on the belt or rotating brush. I applied a bit o

ANSWER : Isoj:

.I have this machine. I use it for my heavy sewing, as it will go through anything. I would be happy to copy the manual and send it to you for copy costs. Just let me know. I would love to know what knowledge you have gained about this machine. It does not appear to be an easy machine to find info on, may not have produced a lot? I had no idea it was not a European produced machine.

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.
