How to Identify and Fix Common Vacuum Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :

There may be a blockage in the agitator brush roller located at the front of the bottom of the vacuum causing difficulty when pushing the vacuum. To check if the roller is stuck, follow this guide here.
This usually occurs if the dust cannister is too full or the filters are clogged and the motor wasn`t getting enough cooling air passing over it.
Loose connections will cause your vacuum cleaner to lose suction. Make sure that the dust container, the hose, the tube and the brush are all attached properly. If the problem continues, your vacuum cleaner might have a technical problem. If you suspect this to be the case, contact an authorised service agent.
Should the brush not rotate freely there may be debris tangled around the ends of the brush, carefully remove any obstructions or replace the brush with a new one. We recommend that you fit a new belt and brush once per year to keep your Reactive vacuum working efficiently.
Clogged Hose

If the vacuum is making a whistling noise, the hose of the vacuum may be clogged with dirt or debris. Use a moist paper towel and/or a long object such as a dowel or a ruler to clean away any obstructions.

Check that the vacuum cleaner is plugged into a working power outlet and that fuses and breakers don`t need resetting. An activated thermal cut-out due to a blockage is the next most likely cause of the problem. Check for blockages in the hose and filters, and remove any obstructions that you find.
If your vacuum cleaner keeps turning off, this could be due to the following reasons: Blockages – check the hose and head for any obstructions. Filter – always check your filters, if these are clogged this could be causing the vacuum cleaner to work harder and lose suction power.
If your Roomba® i Series Robot Vacuum is not turning on or is not able to charge, rebooting your robot tends to solve most related issues. To reboot your Roomba: Press and hold the CLEAN button for 20 seconds. After you release the button, the light ring will show a white clockwise swirl while it reboots.
Clog located in the vacuum hose

Turn the unit on and feel the suction at the end of the hose handle. If there is no or low suction, then the clog is in the hose. You can remove the clog by running a long, stiff object through the hose, such as a butter knife, starting at the wall end.

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.
Roller brush is not spinning

Check to make sure the vacuum is switched to the correct mode. The switch should be in the Power and Brushroll mode to make the roller spin. If it is in just the power mode the roller will not move. The brushroll indicator light should be green when working.

A possible cause might be that the tank is not properly seated. To assure the tank is seated properly, pick it up and re-seat is so it sits snugly on the unit. If this doesn`t fix the problem, make sure the tank is assembled properly. To make sure they are both latched properly, pick the tank up by its handle.
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.
With excessive use and regular exposure to dust and dirt, the filters attached to the vacuum cleaner get grime on them. This dusty layer closes the way for air to pass through the channel. Thus, the machine puts a lot of effort and generates noise in excess to pass the air throughout the system.
The most common problems found in vacuum cleaners are low suction force, excessive noise, burning smell, vacuum not turn on, and overheating. These issues can be fixed by either cleaning the device or replacing some parts of the device. At times, it is best to seek a professional to fix the cleaner effectively.
When not in use the machine should be stored at room temperature. Recommended range: 64°F (18°C) and 82°F (28°C). The ambient temperature range for operation and charging should be 50°F (10°C) to 86°F (30°C).”
Problems can occur when overused or clogged filters cause the vacuum motor to overheat. This not only shortens the motor life but causes a loss of suction. In some cases, total motor burn out can occur.
One of the first things to do when your Dyson vacuum cleaner keeps starting and stopping is to empty the bin. It may be full, or the machine may simply perceive it as too full to continue working. Dyson vacuum cleaners require constant airflow through them to work, and a full bin can stop this from happening.
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.
It`s possible there`s a power consumption issue, with there just not being enough residual charge to run the machine. A new battery should fix this. My other thought is that it`s overheating. If too much power is pushed through the motor, which MAX power does, it could stop after a few seconds if it become hot.
The warm air is perfectly normal. Vacuum cleaners blow air out to keep the motor cool and this may feel quite warm.
On average, a well-maintained robotic vacuum cleaner can last up to 4-6 years, but some models may last even longer.
With proper care, your robot`s battery should last at least 2-3 years before it needs to be replaced.

Terrible noise My dyson was working great then started making this horrible noise. I cleaned the bar but noise is still there. I discovered the beater bar went around three passes then froze and started horrible noise again. my husband got the bar turning but after 2 swipes vacuuming it did it again. Can it be fixed or is it time to retire it and buy a new one. Wendy Kiser
ANSWER : That noise is the clutch. A very expensive part and very hard to replace. When a problem with the clutch happens it’s generally not worth the time and money to replace.

I suggest getting a different type of vacuum, maybe a Miele or Sebo. With the money spent on one of those vacuums, you wont have problems like you would with a Dyson. And the cleaning power is so much more powerful than what any Dyson can offer.

Kirby Sentria Hi, I have a new Sentria & used it for the first time today. It was going fine & then I could smell smoke & it started to make a loud noise so I turned it off quickly. If I turn it on it immediately starts making the noise again & I can see it is all lit up inside like something is burning or sparking. I have checked the roller & it is moving & I have checked the fan which is moving & doesn’t appear to be damaged in anyway. This product is from the US & we are in the UK & we are us
ANSWER : Sounds like the motor burned up. not sure if travel adapters will handle a large load like a motor, around 8 or amps. power needs in US are 110 volts ac, 60 hertz.
I believe UK is 220 volts and 50 hertz.
usually when a vac is brought to europe you must change motor.

When I vacuum w/ the brush control in the on position it make a really loud noise, almost like a grinding sound. I have looked at it and nothing seems to be wrong, but I notice that the pin that engages the belt seems to vibrate a bit, possibly creating the noise. It started when I accidentally got part of a plastic grocery bag caught in the brush. Could it have stretched a belt? Nothing is caught any other place and it only makes the noise when the brush in in the on position.
ANSWER : Yes, the belt could have been stretched and is now vibrating and hitting other parts and creating a noise if much of the bag got caught under the belt. If you have another belt for this vacuum, please put it on and see if the noise stops. If it does, then problem solved, if not let me know and we can try something else and you can send a picture or video to me of the problem.

Let me know how this works out for you.

I have a Model U57809RM Hoover Cyclonic which started making a very loud noise. Changed both belts on it but the noise persists. It seems to happen when I put the handle in the ‘engage to vacuum’ mode. The minute I start to lower it the noise begins. Help!
ANSWER : Hello,

You could have a broken fan in the motor and need to replace the fan. If the noise is coming from the brush area of the vacuum, you probably have a broken bearing in your brush roller and would need to replace the brush itself.

Hope this helps.

Makes a loud noise like a grinding noise then smokes comes out and it smells like burning rubber? When I take the (rod) brush off with the belt then run the vacuum there is no more noise? Please help me thank you
ANSWER : Your belt is worn and stretched and so it is slipping on the motor drive shaft. That is why it is noisy and smells like burning rubber. You simply need to replace the belt. You can get replacement belts here:

Hi folks,
my beam vacuum makes a very loud roaring noise quite often.
the problem started when i was vacuuming up a quantity of vermiculite from my chimney.
i think i overloaded the vacuum i think and it made this loud roaring noise.
the vacuum tends to make thos noise when i am hoovering after 5 minutes or so.
any ideas?.
thanks in advance Tom….
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.
