How to Identify and Fix Common Vacuum Problems ?

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

Vacuum cleaners are fairly simple machines. They need power to be transmitted to the vacuum to create a suction force that lifts debris. So, the usual areas that cause suction loss include the wrong height setting, stuck rollers, a faulty gasket, a broken vacuum belt, a filled bag, or a clogged hose.
Check the hose for any clogs

If your Shark vac has a hose, feel along the length for any lumps. That indicates a clog that`s causing your suction issues. See if you can break the clog by applying gentle pressure with your hands, or gently move it to the end of the hose to remove it.

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.
Check service panel for tripped breakers/blown fuses. If breaker is tripped, reset it. If fuse is blown, replace it. If vacuum cleaner is plugged in, be sure power button is in the off position before resetting breaker/changing fuse.
It is a condition well below normal atmospheric pressure and is measured in units of pressure (the pascal). A vacuum can be created by removing air from a space using a vacuum pump or by reducing the pressure using a fast flow of fluid, as in Bernoulli`s principle.
If done correctly, vacuuming is a key element of good rug health. But if used improperly, a vacuum cleaner can do damage to your rug. For example, vacuuming against the nap or grain of the rug can break carpet fibers and hasten the deterioration of the rug.
Broom and Dustpan

You can use a small dustpan or one with a handle to reduce the need to bend. Start at one end or corner of the carpet and work toward the other end to avoid missing areas. Use short, quick strokes. If debris begins to pile up, sweep it into the dustpan before you reach the end of the job.

Overheated Motor

If your vacuum was working fine and then suddenly shut off, it may have overheated. Most vacuums are equipped with a thermal protector safety switch that won`t allow the motor to run when it becomes overheated. You will need to wait for 30 minutes to 2 hours, depending on your machine, to try again.

Vacuum suction pressure in adults is 120mmHg.

The lowest vacuum pressure is recommended to reduce the risk of hypoxia and tracheal mucosa injury. However, the pressure has to be strong enough to remove the secretion. Usually, it`s between 80 to 120 mmHg.

The type of dust collector or vacuum cleaner bag and the size of it affect the suction power of a vacuum. When a vacuum cleaner bag has an extra filter, the vacuum needs a higher suction power. That way, the air will flow outwards through all the filters.
All vacuum cleaners operate based on air flowing from the opening at the cleaning head or tool, through the vacuum cleaner and the bag and/or filter system and then out the exhaust port. This airflow is created by the vacuum motor, which also may be referred to as the suction motor.

Low suction or poor pick-up may be due to a clog in the vacuum cleaner. If you notice a change in the sound of the motor or a reduction in the spinning action, check for clogs. First, remove the Easy Empty dirt tank from the vacuum and discard all dirt and debris.

The problem started when i sucked a corner of a rug,now it will not **** very much at all??Kenmore upright progressive
ANSWER : This definitely sounds like your belt is broken. The belt is the part that is attached to the motor at one end, and to the roller brush at the other end. If something gets vacuumed up into the brushes that prevents the brushes from spinning, the motor will continue to try to spin the belt, and the motor shaft will then burn right through the belt, or cause the belt to fall off the motor shaft, preventing the brushes from spinning. On an upright vacuum cleaner, if the brushes are not spinning, it will seem like the vacuum cleaner is not sucking well, but in fact the brushes are just not spinning.

To see if the belt is your problem, while the vacuum is plugged, in turn the machine upside down so that the brushes are facing upwards. Make sure that if your machine has a rug/ floor setting that it’s set to carpet mode, and now turn the machine on. Does the brush spin? If no, then this is because the belt has either broken, or stretched out so much that it no longer can spin the brushes.

Here’s a link to the owners manual for your Kenmore that will walk you through, step by step on how to to replace the belt.

Lately we’ve been having plumbing problems to where our washing machine floods up our bath tub and toilet. And it happens while we have the washing machine on of course. Another problem is that whenever we are taking a shower our tub starts to clog up and water starts pouring out from the bottom of our toilet. We had a plumber come by to root out our pipes just last week and it was fine for about 3 days. And now the problem is back and driving me crazy. WHAT IS WRONG AND HOW CAN I FIX IT??
ANSWER : Possible tree roots best thing is to hire a plumber with a camera snake

While vacuuming my carpet, a corner of a throw blanket was sucked into the beater bar. I turned the vacuum off and was able to pull the corner of the throw blanket out without much resistence. I plugged the vacuum in and started it and now the beater bar isn’t rotating.
ANSWER : Try pressing the reset button on the nozzle, probably just tripped out the brushroll motor

Problem starting Sometimes will not start at all. Sometimes will do a quick start and stop. Other times it starts and runs fine????
ANSWER : This can happen if you have an intermittent short in your cord. Try plugging it in and then wiggling the cord around where it goes into the body of the vacuum with the switch set to “on.” (If you’re not sure whether it’s on or off, just click it back and forth occasionally.)
.If the motor kicks on there’s a short, which usually requires a cord replacement. If that’s the case, it’s a relatively simple fix for most dyson models.
.If not, you could have a short in your switch or somewhere else in the electrical system of the machine.

Over heating? My 10 gallon 4HP shop vac has started shutting off after about 30 sec. after I turn it on to use. It smells real hot after I shut it off. I have changed the filter and the bag, which did not solve the problem. Any suggestions on what the problem could be? It’s only about 31/2 years old and I really don’t use it all that much, mainly for getting up dust and cob-webs from my garage.
ANSWER : It sounds like you need to replace the motor in it . thank you for using fixya

I posted my problem earlier today that I was having with my Bissell Little Green Machine not dispensing solution, but sucked up no problem. Someone said that the most common problem was a blockage. We put hot water in the reservoir for 15 minutes as advised and it still will not dispense. The fluid is now ”dribbling”so it is better. It is just not spraying. We are able to blow from the end and make bubbles in the reservoir which shows us it is not blocked. Any other suggestions?
ANSWER : Okay. I fixed this on mine. Undo the screws on the handle, right by the trigger. You pull the tubes off the little valve. Push on the button and see if you can blow through the valve. If not, push a pin around in the valve (with it pushed into the open position) until you can blow through it easily. Then flush it out with water. May take a couple tries. Then put it back together. Make sure you run clean water through it before putting it away. I think the solution tends to dry inside it. The machine never liked cheap cleaning formula.

Arrgh! I have an upright Bissell vacuum. Everytime I use it, it smells like a cloud of dust. I have made sure countless times that all the filters are clean and the hoses are intact, so I don’t know what the problem is. Is this problem normal? Or am I somehow blowing dust everywhere? Any insight it much appreciated, thanks!!
ANSWER : I believe you have a clogg in the suction pipe.

Vacuum cleaner hi.this is 10 yrs old and not overly worked.bags are changed regularly and the micro filter has been changed at least three times over ten years.it goes well for about 2o minutes then loses power with not much “suck”after that.sometimes shutting down completely,because of overheating i presume,or just carries on at a much lower'”suck”.have tied shaking bag inside but no luck.any suggestions out there or can you tell me the agents support office for new zealand[auckland].many thank
ANSWER : What brand vacuum is it?
