How to Identify and Fix Common Vacuum Problems ?

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

The most common cause of loss of suction is that the filters have become blocked. They may require cleaning or replacing. Another cause could be that the vacuum cleaner hose is blocked.
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.
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.

What`s happening with your vacuum cleaner is that a clog has built up and debris being agitated by the roller is spitting out or stirring up dust without sucking it in.
Twist the lid until the arrows line up and open up the container to get to the hepa filter. Take the filter out and brush the dirt out, once a month wash the filter in warm water. Please make sure it is thoroughly dry before popping it back in – this may take around 24 hours.
Rinse the filter

Any fine dust remaining in the filter can usually be removed with a gentle rinse under a cold tap – hold the filter under the running water until the water runs clear. You shouldn`t need to use any detergent – just water.

If you have dirty filters, you`ll notice a stale odor immediately when you turn on the vacuum and reduced suction as you work. For high traffic areas, the filter may need to be cleaned monthly. For most homes, vacuum filters should be cleaned at least every three months.
The most common cause of vacuum cleaner not picking up dirt properly is clogged air filter. Remove the filter and either clean or replace it as needed.
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.

Soil and Plant Debris

Soil and plant debris can clog a vacuum, and damp or wet leaves can lead to mold in the bag or canister, so it`s best to use a broom or your hands to pick those up.

Bugs that do survive the suction and stay alive in the vacuum bag can crawl out. Dispose of the vacuum bag or empty the canister when done vacuuming so that they don`t have the chance to get out. Discard in regular trash bags, and then spray bug killer into the bag or cover/seal it to make sure the bugs die.
Fine particles. Fine particles are no match for even the strongest vacuums. Construction dust, makeup, used coffee grounds, fireplace ash, and other fine particles can burn out the motor and be released back into the air. It`s best to sweep these items up to keep your vacuum – and yourself – safe.
Can you clean a HEPA filter? If your HEPA filter is not specifically labeled as washable or “permanent,” then the answer is no – while it may still filter the air it will have reduced effectiveness after washing.
With the exception of top-of-the-line brands, most vacuum cleaners have a lifespan of about four to six years. While not all machines will need to be replaced after four years, it`s a good indication of when you may need to think about investing in a new one.
For best results the filters can be washed in warm water but check they are thoroughly dry before putting them back into place, this may take up to 24 hours. Hoover recommend that you fit new filters once per year to keep your vacuum cleaner in tip top working order.
Vacuums cleaners can smell from for various reasons; pet dander, moisture was sucked up… The most common cause is old dirt sitting stagnant in the collection chamber, bags, or filters. Vacuum bags should be changed every four to six weeks or once full.
If you`re smelling rubber, the belt has either burned out and snapped or the belt has become so stretched out that the roller is not moving and the vacuum belt is getting super heated from the motors RPM.
Do not use vacuum filtration to filter a solid from a liquid if it is the liquid that you want, and if the liquid is low boiling. Any solvent which boils at about 125 degrees or lower will boil off under the reduced pressure in the vacuum flask. To perform a vacuum filtration, clamp the flask securely to a ring stand.
Add a few drops of soap or detergent into a bowl of hot water. Submerge the filter and squeeze it so it absorbs the cleaning solution. If the water becomes dirty, empty the bowl and refill with more soapy water. Once the water runs clear after soaking the filter, take it out and rinse the suds away.
More people walking into your home increases the amount of dirt and contaminants in your home. Furry pets also introduce hair, dirt, and pet dander. And the more contaminants floating around in your home, the faster your filter gets dirty.
“We would recommend vacuuming at least once or twice a week—and more often if we have pets—with the right tools to remove dust quickly and effectively,” Patel advises.
Most vacuum makers recommend cleaning or replacing filters at set intervals—and those intervals vary wildly. Tineco, for example, recommends cleaning the filters on its stick vacuums after every few uses, while Miele says you need to change its vacuum filters only after every fourth bag change.
The motor in your vacuum cleaner is essentially safe from damage, however, when it is exposed to conditions other than what it was designed for, it can fail. The most common reason for vacuum motors failing is overheating.
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.

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.

I purchased a brand new Eureka Pet vacuum, sorry don’t know exact name but it the one that has the self cleaning duster on it. Last night I used the vacuum on my carpet, it was working fine until I accidently sucked up the corner of a scarf that was hanging off a couch. I shut the vacuum off, pulled out the scarf and and resumed vacuuming. Much to my dismay the suction on the vacuum had ceased. Can you tell me if there is a reset button on the vacuum? The vacuum does not appear to be damage
ANSWER : If the motor is running, there should be suction. Possible problems depend on whether it’s a canister or upright and are:
.A clog in the hose, UR or canister. Detach hose. Drop small coin in one end and lift hose causing it to roll out the other. If it does, no clog in hose. Drop same coin into hose opening on power head. If it rolls out, no clog in PN.
.Broken fan blades, UR. Needs to be taken to shop for repair/replacement.
.
.A reset button is for use if the motor isn’t running, so won’t have anything to do with the suction.

Unbeknownst to me, someone took the bag out of my Kenmore Progressive vacuum and failed to replace it. I have been vacuuming without a bag for months, and today the vacuum stopped sucking. When I opened up the front to replace the bag, tons of dirt and dust came pouring out. I thoroughly cleaned the vacuum, put in a new bag, but still no sucking power. Just dust coming from the rear vents where one of the filters is. Is the vacuum ruined, or is it a simple solution of buying a new filter?
ANSWER : Sounds like you need to buy a new motor. All that grit and dust will ruin a motor and I’m surprised it lasted as long as it did.
.This is where a vacuum that won’t run without a bag would have been nice. (Aerus for one)

I have a Kirby G4 Vacuum Cleaner – MOdel G4 D. I have never had any problems or repairs done to it in the past ten plus years that I’ve had it. This is an upright vacuum. I was vacuuming the carpet floor and was not having any trouble at all. I switched the vacuum off and moved it into a different room. When I tried to turn on the vacuum, it would not turn on. I checked with different outlets, used both front attachment and hose attachment. Checked the front part of the motor/ spiral case. This

The vacuum i’ve had for 6 months has very liittle suction power. checked that the belt is on. cleaned filter. checked to see if hoses were clogged. I used a super vac to suction any debris out of vacuum. still little suction power
ANSWER : As this unit has 3 filters on it, a lot of people forget about the one filter that will cause all of your trouble here.
.
.There is the exhaust hepa filter, no problem, your unit is pretty new, it shouldn’t be a problem.
.There is the circular filter in the chamber where all your dust and debris collects. It is in the top portion and will come out with a twist. This filter is washable. Warm water and no soap.
.
.The third filter, and this is the one that is most commonly overlooked, is just below the dirt container you can take out and clean. It is in a grey “tray” that pulls out and the sponge filter is in the tray. As a word of warning, it is probably pretty dirty. Again just wash it, warm water no soap, and you should be good to go.
.
.PLEASE make sure that the filters are DRY before putting them back into your machine.
.
.Good luck.

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

ANSWER : May be part missing. this is unit has 5-year warranty.you can send to service.
