How to Identify and Fix Common Vacuum Problems ?

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

Hint: If there is suction from the hose but not the main base, there may be a blockage in the base connecting tube or the beater bar may not be rotating. Inspect the base of the vacuum cleaner for blockages and ensure that the belts are not broken.
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*.
One of the easiest ways to increase vacuum cleaner suction is to empty the dust bag or container. Dust containers need to have enough space for airflow, otherwise, they could get clogged and have less suction power. Regularly check your dust compartment and empty or change it when it`s already 70-80% full.
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.
Vacuum means the absence of all matter including air. As there is no air in the vacuum, air pressure will be zero.
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.

The two main indicators to determine vacuum power performance are water lift and airflow. The water lift is measured in mmH2O, mbar or kPa. It represents the suction force and is the reference parameter for vacuuming liquids and heavy materials. The airflow is measured in m3/h or in l/s.
These are the vacuum pressure ranges as measured in Torr (or fractions of 1 Torr). What defines a high vacuum is then that it is normally placed in the range between 1×103 to 1×109 Torr, equaling one thousandth (0.001) of a Torr (or 1 micron) down to one billionth (0.000000001) of a Torr.
Suction pressure should be kept at less than 200 mmHg in adults. It should be set at 80 mmHg to 120 mmHg in neonates.
Use Some Water

A little bit of water can do wonders for boosting a suction cup`s grip. Using warm water, rinse the whole cup so it softens it up. Shake the drops of water off the cup quickly and then put it up on the wall. That can often do the trick.

Gravity and friction are the two main forces that make vacuum suction work. While gravity pulls molecules in the air toward the earth, creating an atmospheric pressure, the suction cup and vacuum pump cause a pressure difference, attaching both surfaces.
So a 1000W vacuum cleaner will use 1 kilowatt (1000 Watts) of electricity in 1 hour. The point here is that it is a consumption measurement, rather than a power output measurement… it tells you nothing about suction. If you want to use more electricity, then use a vacuum cleaner with higher wattage.
Absolute pressure is measured from zero, which means a 100% or a perfect vacuum.
The lowest pressures currently achievable in laboratory are about 1×1013 torrs (13 pPa). However, pressures as low as 5×1017 torrs (6.7 fPa) have been indirectly measured in a 4 K (−269.15 °C; −452.47 °F) cryogenic vacuum system.
Connect a tachometer and vacuum gauge to a none regulated vacuum source on the engine. Disconnect and plug fuel vapor canister vacuum lines. Start engine and run the engine until it reaches normal operating temperature. Note the vacuum gauge reading and any variations in the pointer movement at idle and 2000 RPM.
Vacuum is primarily measured by its absolute pressure. At room temperature and normal atmospheric pressure, one cubic foot (0.03 cubic m) of air contains approximately 7×1023 molecules moving in random directions and at speeds of around 1,000 miles per hour.
The typical range of Pa for a regular robot vacuum cleaner is around 2500 to 3000 Pa. The higher the value of Pa, the greater the force lifting the debris off the floor.
Ultimately though, a suction force of 1000 Pa or more serves as the general rule-of-thumb benchmark for quality vacuuming performance. I did my research to compare the suction power of current vacuum cleaners, from robot vacuums to regular vacuums.
3 0 to 30 inch Hg scale. This simple gauge measures the difference in the levels of the mercury from 0 inches at atmospheric pressure up to 29.92 inches of Hg at the best vacuum attainable. This scale is still in use today, usually shown as 0 to 30 inches of Hg on gauges such a Bourdon dial gauges.
Do not suction too long! The maximum suction time should only be 15 seconds. After suctioning, re-oxygenate the patient.
30″Hg is regarded as the maximum vacuum level available at sea level, and because the oceans are the same height across the planet, this is a good datum point for reference. This number is actually rounded up from 29.92″Hg.
Next, you need to consider suction power. Typically expressed in Pa (pascals), this is a measurement of how powerful the motor is inside a robot vacuum. A good number to look for here is around 2,000Pa or above for an effective clean.

Hi: We ahve a Tornado CV30 vacuum. The suction does not seems to be working properly. There is no suction at the tool hose and the bag does not seem to have air moving into it. Do you think there is a clog somewhere? The roller is moving.
Thank you for youre help 🙂

ANSWER : To clear the clog, remove the hose and wand from the unit and separate them. The hose is.released by pressing the white plastic ring in the housing. The two are.separated by simply unscrewing them. Remember this threaded connection.uses a left-handed, or reverse, thread. By looking through each of these.pieces, the user can ensure they are not clogged. To check the lower hose, it.is easiest to lay the unit on its side. Remove the glide sole by turning the.yellow turn locks to line up with the slots and then removing the glide sole..Remove the yellow connector the wand was plugged into. You should be able.to see the brush through the hose from the rear of the machine.

Electrolux Epic 6500SR Full Bag sensor working, Does not Reset properly
ANSWER : The problem was a sticking switch that was not being reset. The vacuum on/off switch mechanism is comprised of two switches. One is the main switch that turns the vacuum on and off. The second is a shut off switch that gets tripped when the full bag sensor is engaged. This second switch is supposed to get reset when you push the on/off switch on the outside of the machine. The full bag shutoff switch was stiff and it, therefore, was taking a couple of presses of the on/off switch to move the shutoff switch back into the running position.

No Suction I get great suction in the hose, but when I plug the hose back into the unit, there is no suction and the air flow indicator line goes completely red. I've changed the bag and filters. I took the small panel off the back and made sure there is no clog, and took the hose off to make sure there was no clog there. Still no suction. Please help.
ANSWER : I about to say that’s always a clog of some sort that causes that

I have a panasonic mc-ul975 vacuum that works great when working properly. the airflow through the canister seems to stops once the aero blast technology is done running which causes the vacuum to not function as it should (does not have as much suction and the hose/tool accessories do not work at all). if air is continually running through the canister everything seems fine. please help!
ANSWER : Hi there. In Panasonic vacuums2.gif, there is a thermostat protection on the motor. It will automatically shut off the motor if there is no airflow through the motor. This is typically caused by a clogged hose. Typically, if your dust container is that full, there could be backup in the hose. Or the dust container being too full could also or otherwise be the problem. Check your hose for blockage, let the machine cool off, it should start up again

Suction stopped. Roller and belt working-in fine order. Checked hoses have not found any blockage. Blowing out air or sucking so little can’t feel it with hand on hose end. Help!
ANSWER : Either a blockage or the main air filter is blocked , some it can be washed and others it must be replaced

I would check the owner manual and look at the filter, foam ones can and usually have instructions where they install to wash them.

I have an Ecectrolux Epic canister vacuum. As soon as it starts sucking, the vacuum cuts off. I put a new filter and bag in, but it doesn’t seem to help. If I open the front where the bag goes, take the bag out and depress the safety button the vacuum will run. Need some help or direction.
Thank you
ANSWER : Try this.
.Disconnect hose. Turn machine on and place hand over intake. If it shuts off immediately, first try turning dial on top of machine so largest dot matches up with arrow. Turn on and place hand over intake again. If it still shuts off immediately, the “control valve assembly” is worn or broken and needs replaced. Don’t try this yourself.
.Take your complete machine to the nearest authorized Aerus Electrolux shop, or call and ask someone to pick it up. There’s no extra fee for this, or delivery upon repair.
.The repair/replacement should include a complete cleaning of your vacuum in the labor, but ask the service manager to be sure.
.The shop nearest you can be found by typing your zip code into the indicated space on the site listed below.

No Suction I have the Eureka Upright Vacuum. I have no suction when doing regular vacuuming but it seems to have function with just the hose. Also, the height adjustment doesn’t seem to work at all. The vacuum has only be usede 3 times. Thanks
ANSWER : Is your brush roller turning? unplug the vacuum and see if you can turn the brushroller by hand.if it turns real freely the the belt is broke ,if its real hard to turn then something is caught up around the bearings on the ends of the roller.my suggestion is if your having that much trouble withit take it back and tell them you want a new one.if they want to keep your buisness they will give you a new one

I have an old Miele canister vacuum and I do not know how to disassemble the hose to check for a clog. I think it sucked up a nerf ball the size of a ping pong ball. I changed the bag but it did isn’t appear to be in the bag. The vacuum powers on but I do not have suction with the hose, and since the hose has hard plastic elbow joints I do not want to pry them apart and break it
ANSWER : Hi Emily: If you have the model number for your machine you may be able to find your manual on the Miele website. Check here for older models Here for newer models.

In trying to isolate the clog it would be best to disassemble the wand and hose to more easily isolate the problem. If the problem is a ball it is quite likely lodged at the first elbow

Generally, to detach the suction hose from the canister press the release buttons at the sides of the elbow and lift the hose from the socket.

To release the handpiece from the wand, press the locking button and pull the handpiece away from the wand. Similarly if your unit has a floorbrush this can be detached by pressing the locking button and pulling the wand out of the floor brush.

You may need to insert a wire from the canister end to push out the clog or ball opposite to the direction it was sucked in.

If these directions are not helpful and you cannot locate the manual for your model, please reply with your model number as I may be able to locate it from other sources.
