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.
According to our tests, the Shark Vertex Powered Lift-Away Vacuum is the easiest upright model to push, even on medium- and high-pile carpet. We also found the Bissell CleanView Swivel Rewind Pet Reach Vacuum Cleaner easy to maneuver on flat surfaces, though it was a little cumbersome when cleaning stairs.
Bagless vacuums, as the name suggests, don`t use a replaceable bag that collects the dust and dirt from the surface. A bagless vacuum cleaning machine is compact and uses a dust cup or chamber to store the dust and dirt. The dust cup used in the vacuum cleaner can be easily emptied and cleaned.
If the machine will no longer efficiently pick items up, the filter might be dirty. If after cleaning the filter your vacuum is still not sucking things up, turn your vacuum around and pull the red tab at the bottom of your Dyson out.
Why is the vacuum is blowing dusty air out of the back? Simple: the bag or canister is full and the vacuum has nowhere to store the dust it is collecting. Empty the canister or bag. If that doesn`t fix it, the vacuum filter needs to be cleaned or changed.
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.
The best lightweight vacuum we`ve tested is the Dyson V12 Detect Slim. It`s one of the lightest models Dyson offers at just over five pounds, but it doesn`t cut corners regarding features. It can automatically increase its suction power on carpet or whenever it passes over an area with a large concentration of debris.
The Shark Wandvac Self-Empty System is the powerful, lightweight cordless vacuum that empties itself so you can ditch the dirty work. It features HyperVelocity suction power and a PowerFins brushroll to tackle floors & carpets with no hair wrap.
In general, bagged models tend to work more efficiently than bagless vacuum cleaners because they have an extra layer of protection for their filtration system. If someone in your household lives with allergies or asthma, it`s in your best interest to choose a model that will filter out the air as best as possible.
Convenience – One of the most obvious reasons to choose a bagless cylinder vacuum cleaner is because it is much easier to manage. You don`t need to think about buying spare bags – ever! See your dirt – It is much easier to see when the cylinder needs emptying if you don`t have a bag inside your vacuum.
Ensure proper maintenance on the rubber brushes, and filter is also being performed. If the brushes are not spinning properly, this could cause Roomba® to fail to pick up debris off the floor.
Filters need to be cleaned
Rinse the filters with lukewarm water until the water runs clear. Let the filters dry fully before putting them back into the vacuum. If your vacuum is still not picking up dirt, you may need to replace the filter.
Vacuum Properly (and Regularly)
A thorough vacuuming once a week, or even once a day, will go a long way toward eliminating dust. Many new bagless styles come with built-in HEPA filters, which trap even smaller particles of dirt and help freshen the air.
Unfortunately, the answer is no. Vacuum cleaners are very thorough at lifting dirt and debris from the fibres of a carpet but this isn`t enough to kill off dust mites, which live deep within the carpet, rather than nearer the top of the pile – and that takes a lot of suction power.
Certain vacuum cleaners spit fine dust and bacteria back into the air, where they can spread infections and trigger allergies.
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.
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.
Without air in your lungs, blood will stop sending oxygen to your brain. You`ll pass out after about 15 seconds. 90 seconds after exposure, you`ll die from asphyxiation. It`s also very cold in space.
The best vacuum ever constructed on Earth was done at CERN at reported to achieve a density of about 1000 atoms per cubic centimeter. While this is astonishingly low, it is still over 2 million times more dense than interstellar space!
Outer space has very low density and pressure, and is the closest physical approximation of a perfect vacuum.
Based on the vacuums we`ve tested in our labs, bag vacuums tend to have more raw power, while bagless vacuums are more maneuverable. Interestingly, this has less to do with a choice between bags or dirt cups, and more to do with the companies that make them.
Black & Decker`s mini-vac – the DustBuster – was introduced to American consumers in 1979, but the company developed most of the inner workings for the device as the result of a partnership with NASA for the Apollo moon landings between 1963 and 1972.
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.
Bagless Vacuum Cleaners
No need to worry about keeping bags on hand or where to find more. There is no extra expense for buying bags. If your bagless vacuum has a clear cylinder or tray, it`s cool to actually see all of the dust and dirt particles swirling around in the dust cylinder under high pressure.

My filter queen just had the motor rebuilt last year and was basically a brand new unit when I got it back. It is not picking anything up now when I vacuum. The beater bar on the carpet attachment is turning fine and when I take all the attachments off the hose I can feel the suction being created like it should be picking up debris just fine. I have emptied the canister even when it did not have much in it; however, it still will not pick anything up off the carpet. It picks up debris tempo
ANSWER : It sounds as if you have a clog inside the “Power Nozzel”. They mention that there are “no user serviceable parts within the Majestic® Power Nozzle” My advice would be to see if you can see a clog with in reachable distance and try to remove the clog. One way to check for a clog which may work for you is to remove the attachment and shine a flashlight on one of of the attachment and look through the other side and see if you see light, if no light, most likely a clog. Past that you might void the warrenty if you try and open it up the Power Nozzel itself. You may want to ask a Phone service rep about clog removal.

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.

** suction The best way to describe it is that when I was vacuuming I could see dust clouds at the front of the vacuum where the light is swirling around in the air. It was like it was blowing dust around instead of picking it up. I checked the tubing and found that it was clogged with some paper and hair ***** etc…. So I cleaned it out and tried it again and it still was not picking up properly. I had my husband take all the tubing apart to check for other clogging and there was none. When I
ANSWER : You have an airflow problem. You may still have a blocked intake or tube, also check the filter. The air is supposed to go in the bottom (of course) and I’m sure you k**w where it goes out. You probably can **te a reduction in exhaust. If this is a bagless make sure everything is fitting together properly. Mis-aligned components on a bagless can mean little or ** airflow. If this is **t a bagless, try changing the bag whether it is full or **t.

My Dyson Animal has good suction and works fine for actually picking up dirt, but when I use the vacuum with the roller, I hear a grinding/rumbling noise. Its only when I use the vacuum with the brush rotating. It does not happen hen I shut the roller brush off. The belt is fine. I cannot figure out what is wrong as there are no clogs, debris, or foreign objects stuck in the brush or in the belt. The noise seems to be the only issue. The vacuum picks up fine. It just doesn’t sound right a
ANSWER : Trace the path of the suction into the tank and see if there is anything loose or ingested..Also, remove the brush and clean as best you can. Perhaps there is something caught in it. Lubricate where it makes sense with some WD40.

I have a Eureka Altima vacuum cleaner that doesn’t pick up very well. The suction seems fine but the brush roller doesn’t seem to pick up from the top of the carpet. When you lower the height of the vacuum the belt rubs and smells horribly. How can I get the vacuum to pick up better?
ANSWER : That means that you need to replace the belt. Here is the belt you need to replace and the manual which has instructions:
