How to Identify and Fix Common Vacuum Problems ?

A high pitch whistle could indicate a seal is damaged or the machine is blocked. If the noise occurs without the Wand and Cleaner head, it is likely to be caused by either the bin or cyclone.
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.
The sound level at minimum flow rate is quieter than 35dB the sound level at maximum flow rate is 59 dB.
If your machine is making a whistling noise, this indicates that there is a blockage or a damaged or missing seal. Remove the floor tool from the extension tube. Check for blockages and remove as necessary.

If you use a Dyson cordless vacuum cleaner, you`ll probably be familiar with a sort of “boing” sound whenever you stop cleaning as the motor winds down.
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.
A vacuum leak occurs when air enters the engine from an unintended source. These include a cracked or loose hose, a faulty gasket, or a malfunctioning valve. When this happens, the vacuum pressure in the engine can disrupt. This causes the engine to run rough and produce a whistling sound.
A clogged filter in a Dyson vacuum can create a muffled sucking sound or a high-pitched squealing during use. You may need to remove and clean out the vacuum`s filter. Remove the filter by twisting the purple dial labeled “filter” located at the top of the vacuum.
Ultra-quiet operation: The vacuum`s innovative design and engineering allow it to operate at an impressively low noise level, ensuring a more peaceful cleaning experience for users. Powerful suction: Despite its silent operation, the Dyson Silent Vacuum Cleaner does not compromise on performance.
The Dyson 10″ fan produces 50 decibels which is slightly more than a similar sized desk fan that moves 25 times the volume of air.
There is no safety concern. If the noise is intrusive, switching the machine off at the wall will stop the noise, or altering the position of the product in the room might make the noise less audible.
You can eliminate whistling of the sump pump hose when using it for dust collection by distorting the hose with a heat gun. Keep distorting different spots on the hose until the whistling goes away.
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.
If your machine is making a whistling noise, this indicates that there is a blockage or a damaged or missing seal. Remove the hose from the hose inlet on the front of the machine. Place your hand over the hose inlet and test the suction.
If the intake manifold vacuum is higher than normal, the base ignition timing or intake camshaft timing might be too far advanced. If the gauge fluctuates, one or more cylinders are leaking vacuum through a reciprocating part like a leaking intake or exhaust valve or burned piston.

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…

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.

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.

I have the eureka capture vacuum and it works great; however, it has recently started making an extremely high pitched sound when I use it. It is still vacuuming but the noise is so loud it hurts my head and I can only vacuum for a few minutes at a time before I have to turn it off. What is wrong with it???
ANSWER : Dust is getting past the dust cup filter, to the motor. Call Eureka customer service. 1-800-282-2886.

There is a high pitched whirring sound coming from lower part of the vacuum. When I tilt it toward me (while standing in the normal vacuuming stance) the sound sometimes lessens for a minute or so. I have tried the following things:
-cleaned the two sponge filters
-emptied the dirt receptacle
-removed the roller and cleaned it
-cleaned the brushes
-the belt is not ragged and does not seem floppy
-checked all of the airways for clogs (including removing the wheel base)
Can you help?
ANSWER : Your looking for some dirt stuck in some thing you didn’t check yet. with the roller out and the belt out of the way run it to see if it still makes the noise. if it does then you looking at the impeller or the motor bearing themselfs those bearings can be full of dirt or worn out If its running smooth with the belt off then the rooler bearings are next they may only squeel with the belt load on them but install it with the belt off and see if it turns smoothly, ( it should twirl with your finger ) if it turns hard keep cleaning and or replace the bearings, Then run it again to make sure it’s not making the noise hten take it apart again and put the belt on and see if its fixed, It’s possible to put the belt on backwards the brush should be turning as to pull the machine forward on the floor.

High pitched sound when power on
ANSWER : I had a vacuum cleaner that did the same thing. My vacuum had three suction levels. The noise level would decrease as I lowered the level. I also noticed that when I turned the vacuum off the sound didn’t stop instantly, it wound down/faded off as the motor slowed down. I found the problem to be the bearings in the main motor. I’ve been told that the motor that powers the carpet brushes can also make the sound if the motor bearing fails.

High pitched sound when vacuum is on
ANSWER : You may be loosing your bushings on the motor,if this is an expensive machine it may be cheaper to have it fixed,if not it will burn up eventually.Also try taking the beater bar out and make sure you don’t have something rapped around it causing a noise.
