How to Identify and Fix Common Vacuum Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :
It is fairly common to hear rattling sounds in your vacuum cleaner. Often if you vacuum up a piece of hard debris like crumbs you might hear an immediate rattling sound. The sound can continue as items move around inside of the vacuum`s hoses and inside the canister. However, the sound usually subsides quite quickly.
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 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. If that`s not the case, it could be that the device is blocked.
If you park your automobile in a safe space and listen to the engine, you might hear sucking sounds that sound a lot like a vacuum cleaner if you have a vacuum leak. Sometimes a leak can also make hissing or squealing sounds.
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.
You may hear your engine`s vacuum leak from the inside of your automobile if it is bad enough. It will sound like hissing, squealing, or a sucking noise that is similar to the sound you hear from a vacuum cleaner. You can also leave your engine running and pop the hood to see if you can hear the vacuum leak.
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.
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.
Hissing or Sucking Noises
Usually, when the leak isn`t too bad, you will hear hissing noises coming from the engine. This may also sound like whining sounds or whimpering sounds. For more severe vacuum leaks, the noise is sucking or suction, much like a vacuum cleaner.
Overheating due to clogged exhaust filter
The exhaust filter can also get clogged, causing a problem with the motor cooling. Therefore, you should also check the exhaust filter if the vacuum cleaner smells burnt. It is usually located on the top or back of the unit, right where the exhaust air comes out.
Excessive crankcase under-pressure, (vacuum) can occur if the fresh air inlet becomes restricted or the wrong PCV valve is used.
Whirring and whining noises from the engine vary as the car runs fast or slow. These sounds can indicate a number of different problems, including a failing water pump, a bad power steering pump, low power steering fluid, a failing alternator, or problems with the air-conditioning system.
You`ll likely hear squealing or hissing sounds from air sucking through cracks in the intake manifold gasket or vacuum hose. Luckily, these sounds are hard to miss unless you play music a bit too loud.
the vacuum system may be dirty, the pumping line may be restricted or too small in diameter, the pump may be dirty or with too little capacity, the pumping speed may be restricted due to other causes.
Detonation, Pre-ignition (Pinging) Noise
Most people call this a pinging or rattling sound. This noise is caused by an air/fuel mixture in the engine cylinder being ignited prematurely by the heat of compression as the piston is moving up on the compression stroke.
Vacuum Hose Leakage
A broken or disconnected vacuum hose may let excess air into the engine, disrupting the required air fuel ratio. This can cause an engine misfire and slow acceleration.
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.
Start the engine and spray
Scope out all the vacuum lines under the hood. Then start the engine and spray each connection with a light stream of water. If a connection sucks in the water, you`ve found your leak. A vacuum leak can cause a rough idle, high rpm, poor gas mileage and even trigger a check-engine light.
If there is a clog in the vacuum, you won`t have good suction and the vacuum won`t work. The clog can be in the vacuum head, the hose or where the hose meets the actual vacuum.
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.
Run the engine at idle, low cruise (1800 to 2200 rpm) and high cruise (2500 to 3000 rpm). Note the vacuum readings, and any fluctuations, at each speed.
The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound. If you are sitting in a space ship and another space ship explodes, you would hear nothing.
Broken vacuum tube or hose: The most common cause of a vacuum leak is a broken, torn or disconnected vacuum hose or tube. Because of the extreme heat generated by an internal combustion engine, these plastic and rubber tubes can deteriorate or break and cause a vacuum leak.
A leaking cold air intake will often make loud noises as air comes out of the damaged part. You may hear a hissing or whistling sound when your intake manifold has a crack in it. That will let you know that there`s a major problem.

Bad Motor I have purchased two of the Kenmore direct drive beltless systems with Progressive systems. The first died after a year, the vacuum motor start making a grinding noies. I pulled the side HEPA filter and could see a fine coating of graphite like dust. Took it to a vacuum repair shop. They said the brushes were going and thus the motor was shot. I liked the vacuum and bought a second, 1 year later the motor is making a slight noise that and removing the HEPA filter I find a slight metall
ANSWER : That dust is from the carbon brushes on the motor. You may need to check them, and also clean out the motor compartment. A slight noise could be a motor bearing starting to go. Does the smell like rubber or electrical. If rubber, then the belt has stretched and needs to replaced. If electrical, then something is causing the motor to run hot, like a clogged filter, or it could be a motor going bad.

ANSWER : If the filter bag is bad and didn’t trap all of the dust, then it got into your motor, so you may have a problem with your motor now.

My DC 14 makes a terrible noise when I am vacuuming on carpet, so I put it in the upright postion and it stops. I but down the head and the noise will stop. If I bump the head it will start making the noise.
ANSWER : If the noise is rattly then it means the drive belt needs replacing, if your model has a protective brush on/off mode on the front plate where you would normally put your foot, it would have to be repaired officially by a repairer. Replacing a protective drive belt can only be done by Dyson repairers or those that repair Dysons.

Hello, I have a problem with my Eureka Powerline bagged upright vacuum. It has a 12 amp motor and is model #4352, Type D. It was probably bought new in 1998. My problem is, while vacuuming today the motor seemed to slow down all of the sudden and then began smelling like burning rubber. I shut the vacuum off to check for blockages but could not find anything blocked. When I then turned it on again it runs but seems to only be running at 1/2 the motor speed and still has the rubber buring smell.
ANSWER : It sounds like a rubber sealing in the motor has come loose and is being constantly rubbed against the walls of the motor with would cause the smell and loss of motor speed caused by the fricton of rubber against the rod so if you can get to the motor try to open it and see if you can get it if not take it to a small engine repair service hope this was helpful:)

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.
