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.
You may be hearing excessive noise because your filters are dirty. To clean them, watch our Cleaning Filters video. A damaged Brush Roll could also be the problem.
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.
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.

Vacuum cleaner motors can sometimes start making noises of either a dull or piercing kind. Dull sounds can be caused by hair or pieces of string getting wrapped around the impeller, preventing the motor from turning properly. Piercing noises are normally associated with worn motor bearings.
Vacuum cleaners are typically loud because of the way they operate. They work by creating suction and using a motor to power a fan that pulls air and dirt into the vacuum`s collection chamber. The noise produced by a vacuum cleaner is primarily caused by the motor and the fan.
The brush roll or its bearings may be clogged with hair, threads or dirt. Make sure they are clean and the roll spins. The belt may also have slipped because it was loose. Check the fit of the new belt when it is installed.
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.
That`s nothing to worry about. The whooping noise is air coming between the post motor filter and it`s seals. This is very common on DC25, DC40, DC41 and DC55 machines. Yours doesn`t sound too bad, they can be much, much louder.
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. But did you know that the “boing” sound is intentional and designed to give the device a bit of character? Don`t worry, we didn`t either.

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.
If all you hear from the vacuum unit is a click at the when you try to start the vacuum motor from inside the house, then the motor in the unit is dead and has to be replaced. A strong odor from the shellac, which coats the copper coil windings, is an indicator that the motor is about to or has burnt out.
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.

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

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 a Kirby G4 Vacuum Cleaner – MOdel G4 D. I have never had any problems or repairs done to it in the past ten plus years that I’ve had it. This is an upright vacuum. I was vacuuming the carpet floor and was not having any trouble at all. I switched the vacuum off and moved it into a different room. When I tried to turn on the vacuum, it would not turn on. I checked with different outlets, used both front attachment and hose attachment. Checked the front part of the motor/ spiral case. This

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 have a Kenmore canister vacuum – model 25614506. Some time ago, I was not able to turn the vacuum off with the on/off switch, but could still use the vacuum. Turned if off/on by pulling the plug. The other day when I went to plug it in, I heard a pop. Now the sweeper runs but the vacuum cleaner does not **** – no air flow. What could be the problem. The cleaner is only 4 years old.
ANSWER : The motor has an inline fuse

Stopped running My mother’s Oreck vacuum sound as if there was something bogging the rotating brush down. I pulled the bottom cover off and found nothing wrapped around or restricting the brush. I tried to finish vacuuming with the problem then I turned it off to move a chair and turned it back on it would do nothing. Any suggestions as to what could be causing the vacuum to sound as if the rotating brush is being restricted from turning. There was not odor of burning as if the motor was in a bi
ANSWER : Orecks have a plastic fan inside and everything you pick up hits it, sometimes things can get stuck in there or break the fan locking up the motor. With the machine off, poke around where the dirt goes into the motor, behind the roller and see if you can pull anything out.

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.
