How to Identify and Fix Common Vacuum Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :
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.
Vacuum cleaners are fairly simple machines. They need power to be transmitted to the vacuum to create a suction force that lifts debris. So, the usual areas that cause suction loss include the wrong height setting, stuck rollers, a faulty gasket, a broken vacuum belt, a filled bag, or a clogged hose.
One of the most common reasons for your shark vacuum (and most vacuums for that matter) making a loud suction noise is because there is a blockage. They`re a very common issue, and easily fixed. Blockages occur when there is a large enough build up of dirt or dust that it blocks the air flow to the vacuum.
Damaged/Deteriorating Hose
One of the most common reasons that the suction may be weaker than expected is a damaged or deteriorating hose. On most Shark vacuums, there are 2 hoses to check: the short hose between the main vacuum head and the base, and the hose between the handle and the wand.
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.
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.
Gravity and friction are the two main forces that make vacuum suction work. While gravity pulls molecules in the air toward the earth, creating an atmospheric pressure, the suction cup and vacuum pump cause a pressure difference, attaching both surfaces.
Noise Level
Handheld vacuums aren`t as loud either, coming in at around 60-70 decibels. Upright Shark vacuums, however, can be as loud as 70-80 decibels since they have powerful motors.
If the tube is making a hissing noise, there could be air leaking from the tube which prevents the vacuum from picking up dust. The tube`s body may have been damaged by fast moving debris or the connection of the tube to the main body could have loosened through the vibration of the vacuum.
Check for a plugged hose:
Plugged vacuum hoses are sometimes the reason for a loss in suction. Hoses can get clogged with hair, dust bunnies, string, or anything else that can`t pass through the other end of the hose. Airways inside the machine should be looked at as well. Wherever there is an air passage, check it.
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.
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.
Q: What Can I Spray to Check for Vacuum Leaks? A: Any sort of flammable liquid can be used. Carb cleaner, brake cleaner, starting fluid, and propane are all commonly used for the process as they will increase the engine speed when they enter through vacuum leaks.
If the leak is located near the end of the hose, use a pair of pliers to remove the plastic connector from the end of the hose. Then, use a utility knife to cut off the end of the hose above the leak. Replace the connector and reattach the hose to the vacuum cleaner.
All vacuum cleaners operate based on air flowing from the opening at the cleaning head or tool, through the vacuum cleaner and the bag and/or filter system and then out the exhaust port. This airflow is created by the vacuum motor, which also may be referred to as the suction motor.
It is important to check your vacuum filter regularly and replace it when necessary. A clogged air filter will decrease the suction power of your vacuum cleaner and make it less effective at removing dirt and dust from your home.
Suction pressure should be kept at less than 200 mmHg in adults. It should be set at 80 mmHg to 120 mmHg in neonates.
Vacuum suction pressure in adults is 120mmHg.
The lowest vacuum pressure is recommended to reduce the risk of hypoxia and tracheal mucosa injury. However, the pressure has to be strong enough to remove the secretion. Usually, it`s between 80 to 120 mmHg.
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.
70 decibels is as loud as a washing machine or a dishwasher. It is a moderate noise level. 70 dB noise is not considered harmful to human hearing. However, extended exposure to levels above 55-60 dB can be considered disturbing or become annoying.
Check the Rotator Brush and Wheels
Sometimes pieces of string or other objects get wrapped around your vacuum`s rotating brush or around the wheels of the vacuum. Unplug your vacuum. Turn it over and have a look at the wheels and brush. If you see any pieces of string or objects lodged there, remove them.
Vacuuming every day, or even a few times a day, is not going to create any long term problems. `But,` you might be thinking, `doesn`t the brushes spinning over the carpet on a beater bar wear it out? ` Sure, but a very small amount.
Most cleaning experts will tell you to vacuum your floors once or twice a week depending on how much foot traffic those floors are getting. Cotter says that high-traffic areas should be vacuumed twice weekly, as these areas have a higher level of dirt, and vacuuming this frequently will prevent matting.

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

Vacuum My vacuum is loosing it’s suction power. I’ve checked the belt and it’s in perfect shape…I’ve bought a new filter cup…I’ve checked for clogs and there aren’t any…I’ve cleaned the entire machine…and I still can’t find the source of the problem.
ANSWER : You checked the belt, but I bet it has stretched and won’t drive the brush roll under load like it should. Belts only last a few months the stretch and should be replaced. Iff you have suction at the hose, then it has to be down below, either belt/brush roll, or the inlet by the brush roll is clogged.

Won’t start. My son was using the vacuum & Didn’t change the bag. The vacuum was making the full bag smell, but the light was’t on & it didn’t stop. I stopped him, changed the bag, checked the filter, closed the compartments & turned on the vacuum. Nothing happened. I checked to be sure that it was plugged in, that wasn’t the problem. I’ve let the vacuum “rest” for several days, It still won’t start. Any suggestions?
ANSWER : There is a reset button at the back of the powerhead. The user manual can be downloaded from the electrolux website, although I didn’t find it very useful. There was some info on how to change the powerhead drive belt.

When I flip the switch on my sebo x1 upright, a red light comes to the brush and bag icons. However, I cleaned out the hose and checked to make sure there is no obstruction from the brush to the hose also, or from the hose to the bag. It is clear that juice is coming to the vacuum, but there is no sign of life except the two red lights.
ANSWER : Thanks for contacting fixya. You should pull out the bag and reset the machine. You should take all the user replaceable items. And turn it on. You will get lot of errors. Then turn the machine off. Put back all the accessories and the bag. Turn you machine on. This will solve your problem.

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 🙂

My Kenmore bagless intelliclean vacuum is making a loud noise mainly when it is vacuuming on the highest setting (when the light is red). We have taken it apart and cannot find a clog. It has also lost suction.
ANSWER : This might help, it was posted on a previous problem but is the same issue you are having it seems: “Here is a possible solution. If the vacuum sounds normal when the green light comes on, then the issue is a suction bypass. Kenmore built a suction bypass in to help cool down and protect the motor should someone either never clean the filter, empty the canister or somehow manage to clog the hose. There is a spring holding the bypass closed and is overridden by vacuum suction. I guess the spring becomes weak, allowing high suction to pull it open which in turn reduces suction so it closes again. It can do this several times per second making a loud racket and slightly affecting performance until the sensor goes green, then the vacuum suction is too low to overcome the spring tension thus why it sounds fine then. The trick? The very hard way (what I did) was to open the vacuum, open the casing where the spring is and pull it apart slightly to increase the spring tension. The easy way is to put tape over the hole where the bypass is. The inlet is under the hose track on the back on the right side as you’re looking at it. The hole is about the size of a quarter and you’ll see fins across the hole. The tape would keep the suction. The motor would still pull back the bypass but since tape is applied, there would be nothing to reduce the suction thus keeping performance and reducing the noise. However, this circumvents the intended design so you do so only at your own risk.”
