How to Identify and Fix Common Vacuum Problems ?

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.

For a vacuum cleaner to glide easily on a carpet, air must flow into the nozzle and through the machine. Block the air flow and the vacuum seals itself to the carpet and is hard to push. And, unfortunately, that`s what many consumers have discovered when their new carpeting is installed.
First check the airflow valve located under the handle. Sliding this open may make it easier to push your vacuum. It could also be that your suction is set too high. To fix, use the suction controls on the canister to adjust the suction settings.
We have two possible ways of adjusting the pressure in a vacuum system: first, by changing the pumping speed (altering the speed of the pump or throttling by closing a valve); second, through admission of gas (opening a valve).
Vacuum cleaning is one of the household chores that may leave us with pain. That is because while using a vacuum cleaner, weight is transferred back and forth between the back and the front lower limbs. Vacuum cleaning also involves bending which indirectly puts pressure on the lower back.
Using the Crevice Tool

Most good vacuum cleaners come with attachments that are designed to make it easier to vacuum hard-to-reach spaces. The crevice tool is an attachment that comes with most vacuum cleaners and it typically features a narrow end that can fit in most tight spaces.

Push harder than you pull.

Many people naturally exert more force when they`re pulling their vacuums back than when they`re pushing them forward, but this can leave dirt on the floor. Vacuums are designed to be pushed forward at a rate of about 12 inches per second and pulled back at a rate of 6 inches per second.

If this is normal air pressure at sea level, then the force is around 15 lbs for every square inch of the surface area of the container. If you`re deep underwater – then it could be tons per square inch.
Because the maximum theoretical vacuum at sea level is 29.92 in. -Hg, actual pump capabilities are based on and compared to this theoretical value. Depending on pump design, the vacuum limit ranges from 28 to 29.5 in. -Hg or about 93% or 98% of the maximum theoretical value.
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.
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.

Common causes of tense muscles include trauma, overuse or repetitive stress, and poor posture. A sudden traumatic injury from lifting improperly, a fall or an accident, sometimes referred to as “throwing out your back,” typically leads to pain, inflammation and muscle spasms.
Any vacuum can clean hardwood floors—this is the simplest possible task for a vacuum cleaner. You don`t need anything special to get dust, hair, crumbs, or anything else off your wood, tile, or laminate floors. But some vacuums do it a little better than others.
A hard vacuum denotes a more complete vacuum is created in the tube manufacturing process. Hard vacuum tubes – like the 6L6 and 6550 – have a higher saturation threshold and therefore distort less easily then soft vacuum tubes.
But cotton swabs can make it fast and easy to to clean out even the tightest spaces. Use a cotton swab to brush away loose dust and dirt, or dampen it with a bit of rubbing alcohol to wipe away stubborn gunk.
When isolated strands pop up with vacuuming, this is called sprouting. With shedding, fibers are no longer connected to the carpet, but with sprouting, fibers remain attached. To resolve the problem, simply clip sprouts to an even height with the surrounding pile.
“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.
Take your time. Vacuuming slowly will allow your machine to suck up more dirt and dust, and ultimately get your rugs and carpets much cleaner. Slow vacuuming allows the brush to agitate the carpet properly and suck up the unclean bits that emerge.
Yes, normal forces, and friction exist in vacuum. Normal force could produced be a machine pushing a body against a wall or another machine, or ground.
Ultimately, a perfect vacuum isn`t possible because quantum theory dictates that energy fluctuations known as `virtual particles` are constantly popping in and out of existence, even in `empty` space.
What is a Good Suction Power for a Vacuum Cleaner? An upright cordless vacuum cleaner should have at least 100 air watts to effectively clean a variety of floor surfaces, with the best Samsung vacuum cleaner reaching up to 210W*.
What is the limit for humans in reducing pressure in a straw by sucking? Checking around on the web, the general finding was that a human can drop the pressure about half…to around 7 psi.
Putting in the incorrect amount of oil, putting in the wrong type of oil, and oil contamination can all cause the pump to not reach full vacuum. For this reason, you must check the oil regularly to ensure that it is not only clean, but also properly filled.

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.

When pushing foreward the vacuum is hard to push and if pushed on to hard it will turn over on itself.
ANSWER : My dyson dc17 animal had become nearly impossible to push on carpets.

sure enough i found that my roller was warn down to nubs (vacuum is probably 8 years old, and gets used nearly every day)

I replaced the roller and WOW! it feels like its self propelled now. HUGE DIFFERENCE.

thanks for the help!!

My Kenmore 35922 works well on floors, but it recently became very difficult to push on carpet. The brush spins and a local vacuum repair guy wouldn’t solve my problem since the vacuum worked fine on his very flat, commercial carpet. What can I do to get my easy to push vacuum back?
ANSWER : Hi dalee196,

There are three common reasons why vacuum cleaners are getting hard to push.

1. Base is dirty – The base needs to be clean from dirt and tar.

2. Height is too low – You might want to consider adjusting the height up a little bit.

3.Belt broken or worn – If the belt is broken or already worn this will cause the machine to be hard to push.

Checking all these can make your vacuum easy to push on carpet. Especially checking the belt.

Hope it helps.

Thank you for using Fixya.

I have a tank style vacuum. When I vacuum with the power head it dims and slows down when I push the power head back and forth, but it powers back up louder when I stop pushing it If i remove the powerhead from the hose the vacuum works fine.
ANSWER : Most likely the belt. Thats the cheapest so try it first

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
ANSWER : Hello,
.My educated guess is that it’s either the switch or the power cord. Here are a couple of guides to help with diagnosis and repair…

The suction is good, but it can’t pick up most of the stuff on the floor. The hand held hose works very well, but it doesn’t even pick up little fuzzies reliably when I push it along. And, the suction is too hard I think because it used to push easily and now I have to push really hard, even on flat carpet.
ANSWER : Check entire length of hose, including the piece in the power head, for clogs. Simply drop a marble in one end and allow it to roll out the other. If it doesn’t, then the hose is clogged somewhere.

My windsor sensor 12 inch vacuum is to hard to push. I bought a new one and its doing the same thing. My vacuum repair man says he cant fix the problem. My shoulders are sore from working so hard. Help
ANSWER : It\\’s possibly the type of carpet you\\’re using it on. The sensors use the brush speed and the amount of air flow to determine carpet height. Some berber, and tweeds make these things horrible to push. We sell sebo, who make the windsor and we\\’ve had the same issue on random carpeting. We end up selling the G- Series units in these situations because they adjust manually so not to suck themselves tight to the floor. Sebo/Windsor make amazing products but there\\’s just no helping this, it happens sometimes.
