How to Identify and Fix Common Vacuum Problems ?

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.
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.
The most common cause of a washer making a loud noise during the agitation cycle is a worn-out drum bearing or broken drive pulley. These defects usually cause a grinding or rumbling sound when the drum spins.
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.
Most problems with robot vacuum cleaners making excessive noise are caused by obstructions that are blocking airflow or preventing parts from moving freely. You can generally resolve such issues by clearing any blockages or obstructions from the unit. Check that no hair or other debris is tangled around the brushes.
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.
The powerful airflow from the vacuum can help shake dirt and debris loose and pull them into the vacuum. Without the fan, a vacuum couldn`t work at all. But the roller brush is critical, too. It`s necessary in dislodging deep dirt and stuck debris, and it helps clear a path for air to carry dirt into the vacuum.
There are varying degrees of quality and value when it comes to vacuums; if you paid a lot for the appliance, repairs are likely worth it, but we recommend that you don`t spend more than half of the original price for any repairs.
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.

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.
If your machine is making an abnormally loud noise it is likely due to the belt slipping or the brush roll being incorrectly installed, follow these steps to resolve: Turn off and unplug machine. Use a Phllips-head screwdriver to remove 3 screws, 2 in the belt cover and 1 on the brush roll mount. Remove belt cover.
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.

Hoover Savvy making grinding noise after getting sheet stuck in beaterbar
ANSWER : Sound like the bearing are shoot

Weird noise i have a eureka the boss and i am getting a weird noise figured bag was full needed to change it so i did. Noise persisted so i checked make sure nothing was caught in the brushes. I even checked the belt it was fine replaced with a new one.Still the noise is there help me I am out of what else to check.
ANSWER : Squealing

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.

The vacuum is making a noise like something is stuck when it is in the carpet position but not when in the floor position. I can’t find anything that is stuck in the areas that I can see. I have cleaned the brush but it does not seem to want to turn. Does this machine need to be oiled so the roller will turn? Is there a way to check inside the motor? Do you think that because the brush won’t turn that is making the noise? Do you know of any repair shops in the Lake Havasu City, Arizona area?
ANSWER : As far as the roller brush goes, yes, it does need to be cleaned. Follow the directions to remove it and clean as best you can of all debris. On both ends of the roller brush there will be two “holders” of sort that connect the brush to the frame of the vacuum. These need to be able to turn freely around the brush. Clean them as best you can and spray some WD40 in between the roller and both the holders. Work the holders around by hand to be sure they move freely..I would also check to see if your belts are snug..
.Please let me know if this does not help solve your problems..Paul

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.

Electrolux Hi-light Hi, my hoover is making a weird knocking noise and emitting a burning smell. Took the lid off and the belt *seems* okay, but still makes the noise and the smell….
ANSWER : Burnt smell is probably the belt slipping. Even though it looks OK, either the belt needs replacement and/or the roller needs cleaning and/or lubrication at the ends. Try cleaning the roller ends first and then light lubrication with WD40. If belt works, you are done. If not, replace belt.

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.
