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.
Possible Causes: The brush roll is blocked. The cleaner might be overheated. The battery is empty (last LED blinks)
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.
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.
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.
Many reasons can cause low refrigerant suction pressure, i.e.: low indoor temperature, dirty filters, restricted ducts, undersized ducts, closed dampers, frosted coils, restricted refrigerant line, restricted piston, incorrect piston, restricted strainer, bad indoor blower motor ect.
Check that the vacuum cleaner is plugged into a working power outlet and that fuses and breakers don`t need resetting. An activated thermal cut-out due to a blockage is the next most likely cause of the problem. Check for blockages in the hose and filters, and remove any obstructions that you find.
If your vacuum cleaner keeps turning off, this could be due to the following reasons: Blockages – check the hose and head for any obstructions. Filter – always check your filters, if these are clogged this could be causing the vacuum cleaner to work harder and lose suction power.
Suction pressure is the negative difference in pressure between two places that drags liquid or gas from a higher pressure state to a lower pressure state. The suctional force in plants is caused by transpiration. This force aids the plant in obtaining essential minerals from the soil.
The suction power is measured in Watt (W) and is typically between 250 W and 450 W for machines with 1 motor. The suction power is to be measured at the end of the tube of a complete vacuum cleaner (i.e. with tube, hose and filters – but without nozzle).
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.
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.
Apart from refrigerant leaks causing loss of critical charge, the most common problem associated with low suction pressure is: LOW LOAD, i.e., not enough warm, moisture laden airflow across the evaporator coil. Classic causes: Undersized duct or poorly designed and/or poorly installed air distribution system.
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.
Vacuum cleaners use an electric motor that spins a fan, sucking in air – and any small particles caught up in it – and pushing it out the other side, into a bag or a canister, to create the negative pressure.
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.
What is vacuum suction? A vacuum suction massage treatment is a mechanical lymphatic drainage treatment. It is used to stimulate the lymphatic system and aids: removal of waste products, draining lymph from the tissues.
In vacuum handling technology and other applications that operate in the rough vacuum range, the vacuum level is typically measured using direct-reading gauges. Direct-reading gauges can provide an accurate measurement from atmospheric pressure down to about 1 Torr and in some cases lower.
Max(4000 PA): It can deeply clean the place that needs cleaning, dust cleaning is up 80%, garbage collection is up 30%, and the cleaning times are up to 80 minutes.
For an open tank under atmospheric pressure, the maximum suction pressure you can get is 1 atm + pressure due to height of liquid inside the tank + pressure head due to velocity of liquid.
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.
Low intermittent suction is usually ordered. Low range on the suction device is from 0 to 80 mmHg. Starting between 40-60 mmHg is recommended. The suction level should not exceed 80 mmHg.

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.

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.

Electrolux Epic 2500 suction stopped – Electrolux Vacuums
ANSWER : It could be the switch or could be the suction motor. Also, there is a thermostat on the motor that will shut it off if you don’t have the air flowing to keep it cool. If that is the case, the motor will re-start after it cools down.
.If the motor dosen’t start, the cheepest way to start is to buy a new switch and install yourself. Just make sure where the wires go. The single terminal is to the front and the two terminals to the rear. The black wire goes to the front single terminal, the red wire goes to the far back terminal and the blue wire goes to the front back terminal. The suction motor should come on first and then the power nozzel. If not in that sequence,reverse the blue and red wires.
.If that fails, take it to the Aerus/Electrolux shop.

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.

Need Kirby Generation 3 Vacuum cleaner manual. Vacuum is not picking up dirt from floor. Seems to have enough suction to inflate the bag, but when you check the suction under the vacuum, there seems to be extremely litle suction.
ANSWER : If your brush roll is turning and your bag is not overly full, then the only other thing it can be is a clog where the bag connects to the vacuum. Turn the plastic part out away from vacuum and lift off to see if you have something clogging it. It would have to be something big, but not so big that it could not get past the fan. As a rule of thumb, KIRBY never clogs. I suspect that your belt is stretched out and your brush roll is not turning while on the carpet so the brush roll is just in the way rather than brushing your carpet to pick up dirt.

No suction I am getting no suction on my central vac at the vac. I do not believe that the piping is plugged up, the vacuum is not creating suction. What are the causes of no suction at the vacuum and how do I take the top half of the Nutone central vac off?
ANSWER : Use the guide at builtinvacuum.com/flowchrt.html to find the issue and solution. Most likely you need to test it without any filter and be sure the bottom of the unit is attached 🙂 To get access to the motors you need to unbolt the very top sides.

Suction Problem I was vacuuming and stopped to empty the cannister. When I started vacuuming again – the suction wasn’t working properly. The vacuum was just pushing stuff around the floor. I cleaned the hair out the brush on the bottom and it still isn’t working. It was working fine before I emptied the tube 🙁 I can’t figure out what happened.Help!
ANSWER : Greetings from GoVacuum,
.
.I believe what may have happened is that your vacuum cleaner belt has either broken, or been stretched so far that ithe brushes are no longer spinning fast enough.
.
.Here’s what you should do to diagnose this problem.
.
.1. Take the suction hose out of the back of the vacuum (assuming that your vacuum has on-board tools), and see if you have any suction coming from the hose. If you do, this indicates your belt is bad.
.
.2. If you don’t have suction coming from the hose, then it may be something as simple as replacing the filters, to a clog in the vacuum, or to your motor going bad.
.
.In my professional opinion though I would say from what you stated that the belt is mostly likely going to be your issue. If you can provide me the model number of your vacuum cleaner, I can walk you through step by step on ow to replace the belt.
.
.I have posted a short YouTube video on a vacuum belt change, this is not for all vacuums, but it will give you some idea of how to change a belt;

Suction problem I have a Hoover Widepath Fold Away, 12 amp motor vacuum cleaner and the problem I am having is every time I vacuum, the vacuum gets clogged up with carpet. I am probably only able to do one stroke then it gets clogged and I have to stop and unclog it or it spits it out on the carpet. This is very frustrating and I don’t get much vacuuming done. Please can you help me. Thank you. Gwen email is [email protected]
ANSWER : Get rid of the carpet its shredding and falling apart.no sence in vacuuming old rotten carpet.or try using a vacuum without a brush roller and just suction
