How to Identify and Fix Common Vacuum Problems ?

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

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.
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.
Worn out bearings on the brush roll will make a vacuum much noisier. This is a good time to check them after cleaning and inspecting the brush roll. Try spinning each bearing by hand. Some brush rolls have only one bearing on the roll, and the other bearing is in the head where the roll is mounted.
If the cleaner becomes noisy or starts vibrating, it may be because some debris has got tangled around the brush roll or agitator situated in the bottom of the cleaner.
Sound enclosures, noise reduction blankets, sound curtain noise barriers, or sound barrier walls are a few options to consider when reviewing noise reduction materials. If the vacuum pump is indoors, a noise enclosure would be the recommended solution.
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.
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.
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.
Manifold vacuum, or engine vacuum in an internal combustion engine is the difference in air pressure between the engine`s intake manifold and Earth`s atmosphere. Manifold vacuum is an effect of a piston`s movement on the induction stroke and the choked flow through a throttle in the intake manifold of an engine.
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.

Miele Cat & Dog vacuum gets VERY hot and is VERY loud. Hose has no restrictions and I have changed the dust compartment (motor) filter and the exhaust filter. It still gets hot when I run it with the top open and all filters removed, so I’m guessing the problem is with the motor. Should I be going into the motor compartment? If so, what am I looking for?
.The fact that it gets very hot could be due to a number of issues.,but the fact that it started making a very loud noise at the same time suggests that there might be more problems maybe brushes etc.
.If you could describe the sound it makes like a squeeling or electrical buzzing I know this might be difficult ,but it would help in the diagnosis.
.I will try to get more information on the unit ,meanwhile here is the user manual pdf if you don’t have it:

Motor getting really loud!
ANSWER : Your Kirby most likely needs a new fan. Please see this link to get the part and do it yourself repair instructions…


I need to change the motor in a vax 6131 but i don’t know how to get into it to get the change it?
I also need to get into the motor assembly housing to change a part but can’t see how it comes apart!!
ANSWER : On the handle there is one small pozidrive screw, remove and orange panel comes away revealing powercable securing bar. Remove 2 screws and this reveals a 10mm headed bolt. Under label on top of handle there is another small pozzi screw, undo this and the handle cover can be removed revealing the other 10mm bolt which needs to be removed. The upper orange cowl can now be eased upwards and if you note where the 2 switches are located, they can be eased from the handle area by depressing the switch locating clips. This allows the upper cover to be put to one side with the power cable still threaded through. DO NOT REMOVE any of the connectors from the connections otherwise you might need a competent electrician to help you. At this point there are 3 similar 10mm bolts which, when removed, allow the bottom black plastic ‘ring’ to be removed from the orange plastic with the motor attached. You then should be able to replace the required..—————————————–.—————————–.To disassemble a  vax you first remove 2 screws holding the handle cover. One is just above where the power flex enters the handle, the other is at the mid-point of the top, hidden under the label. Both are small crosshead screws. Before doing attempting this, you need to be competent with working on mains electric wiring, as some of this has to be removed to do all this. 

Once the handle covers are removed, the next bit is to gently lever off the speed control knob – it’s a tight friction fit, then undo the nut holding it to the handle cover panel. After this undo the mains power connections from the multi-block joiner they go into then remove the 2 screws securing the mains wire. Then undo 2 bolts at each end of the handle going downwards into the main body. At this point the handle can be removed as well as the top body plate. You have to fiddle the electrics and switches through the hole in the top body plate to remove it. Now 3 bolts and a small crosshead screw is all that holds the upper motor section to the lower. Remove these and you can separate the 2 halves which gives you acess to the water pump. This is held in by screws founf underneath the plastic ring at the base of the motor body (around where the small reound blue sponge filter goes). This ring is held in by plastic springy clips. Gently lever round it to get it come off.

Shopvac 90L400 quit working (4 years old). Thought the switch was bad but not the problem. I read that there is a fuse link in the motor that frequently burns up. I tried to take motor apart but not sure of the process. I was able to get to the motor but cannot pull it out of the armature. It appears I have to take the aluminum blower unit off the shaft (it appears to be pressed on with a retaining washer). Do I have to take it off to pull the shaft and motor assembly out? Is that where the fuse
ANSWER : By pass the switch and take power right to the motor leads.. that should tell you if the motor is ok.. have not seen fuse link on a vac motor.. graingers has new motors, but not inexpensive

I have a window fan with two fans in it & I cannot get the cover or back off so I can clean it. I* have taken all the screws out that I can get to , but there are two clamps that I can’t get off, I’m not sure why the clamps are there but they are on the side with the accordian extention. Please tell me how to get it apart – after 2 years it is really filthy!!

Thank you,

ANSWER : Remove all the screws, pry clips off that hold on the extensions, than fan will pull apart. The clips must be pried off. They will not break. Then remove screws holding in the fans and remove them as well. Fairly simple process.

Bissell 6591 operating twice as loud as before.
ANSWER : Hey Mike! Excessive noise can be contributed to dirty filters or clogs. Here’s a quick link to troubleshooting steps to assist you..

I can’t get the vacuum to **** and can’t get to the point of the clog. The pieces don’t come off. Also need to know how to get the filter piece off the machine.

Loud noise?? my vacuum suddenly just got really loud. it suctions fine, i changed the belt, but when the roller is off its not loud, but when i put it back on the 11noise is horrific. it vacuums fine i just cannot stand the noise. please help
ANSWER : I have the exact same problem. I’ve taken the thing apart and cannot figure out what is causing the noise. It’s not the belt and it doesn’t seem to be coming from the engine. It sounds like the spinning brush is hitting something, but it’s not, that I can see.
