How to Identify and Fix Common Vacuum Problems ?

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

A possible cause might be that the tank is not properly seated. To assure the tank is seated properly, pick it up and re-seat is so it sits snugly on the unit. If this doesn`t fix the problem, make sure the tank is assembled properly. To make sure they are both latched properly, pick the tank up by its handle.
Check to make sure the Vacuum Suction Knob is turned towards “Floor Suction.” Or there could be large debris clogging the brush roll rotation. Your dirt container may not be seated properly or may be full. Press the Tank Release button and remove.
Check for a plugged hose:

Plugged vacuum hoses are sometimes the reason for a loss in suction. Hoses can get clogged with hair, dust bunnies, string, or anything else that can`t pass through the other end of the hose. Airways inside the machine should be looked at as well. Wherever there is an air passage, check it.

Check to make sure you are using the appropriate setting. For example, if your vacuum is set to “bare floor” and you are trying to vacuum shag carpet, there simply is not enough room for the brush to rotate properly or for air to flow. With the proper height setting, your vacuum should move easily.
Most carpet cleaning pros say they use a range of 100-400 psi for regular carpeting, but some use a psi as high as 500 for standard jobs. For more delicate fabrics, such as thinning cotton or nylon, you may need to go as low as 50 psi.
We do not recommend leaving dirty water in the cleaner.
Dirty filter: If the filter is clogged with dirt and debris, it can cause a musty smell. Check the filter and clean or replace it as needed. Mold or mildew: If the machine is not properly cleaned and stored after use, moisture can accumulate and lea.
Overcharging leads to overfeeding the evaporator with refrigerant, which leads to higher suction pressure. Another possibility is having oversized EXV causes an overfeed to the evaporate, which increases your suction pressure.
Low suction pressure/low superheat:

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.

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.
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*.
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.
Vacuuming every day, or even a few times a day, is not going to create any long term problems. `But,` you might be thinking, `doesn`t the brushes spinning over the carpet on a beater bar wear it out? ` Sure, but a very small amount.
How often should you vacuum fabrics, carpet, and rugs? Anything with fabric or upholstery needs frequent vacuuming. Dust settles deep into the fibers, holding onto pollutants, bacteria, and unwanted smells. Plan to vacuum carpet and area rugs at least twice per week, even if they don`t look dirty.
When cleaning your carpet with baking soda, let it sit for at least 15 minutes. The longer the baking soda stays on the rug, the more odor, dirt, and oil it will absorb, for a more thorough clean. Try leaving baking soda on the carpet overnight and vacuuming in the morning.
The level you set your vacuum depends on the height of your carpet. For bare floors, use the lowest or bare floor setting, for short and medium pile carpets use a medium setting and finally, for plush carpets use the highest setting.
A vacuum cleaner is designed for dry debris and a carpet cleaner is for stains. For example, a carpet cleaner is better suited for a pet stain, but a vacuum should be used to tackle their loose fur. In instances where you need to clean a mixed medium like mud, it`s safer to use a carpet cleaner.
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.

Locate the brush reset button on the lower back right of the vacuum. Press the button to reset the brushroll To ensure the brush has been reset, plug the vacuum back into the electrical outlet.
A: It does not heat the water. Fill the tank with hot tap water, add the cleaning solution and it`s ready to clean.
It does not heat up the water. You are supposed to add hot water to it before using.
If you clean something with Dawn dish soap in the Bissell carpet cleaner tank, you won`t be able to suction out all of the soap without switching to a tank of just plain water. If you leave soap behind in whatever it was that you were trying to deep clean, it can actually attract and trap dirt in the fabric.
Your BISSELL Steam Mop has been designed to be used with tap water although to prolong its life the use of demineralised water is strongly recommended.

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.

No suction Just received my refurb. dyson animal bagless. Finally figured out how to get it all together, turned it on and there is no suction coming up thru the beater bar. The hair is just collecting around the bar and not going up into the canister. It appears all the suction is going thru the open red end of the attachment hose, which has a vented cover piece. Am I missing a piece or is there a switch to turn of the attachment suction?
ANSWER : So the red hose isn’t connected to a part on the vaccum so like it is connected to the connester but not to an opening just above the beater bar, this is the only idea i can supply you with. good luck, maybe i got lucky and helped you out.

I am getting very little suction from the motor. The hose is clear, the bag new. When I open the bag cover, plug the hose in and turn the vacuum on, there is next to no suction from the motor. What do you think is wrong? How do I remove the cord retractor to get to the two screws that hold the back of the canopy cover?
ANSWER : Your problem is probably is you don’t have a proper seal in your chasis. A vacuum has to be sealed tight or the air will leak out and the seal broken. Check around the whole body after the bag is in and check for any airflow noise. I could help more if I knew the make and model. Chris

No suction from my Little green machine – Bissell THE BISSELL LITTLE GREEN MACHINE Vacuum
ANSWER : Hello and welcome to FixYa;

Make sure the collection tank is not full,

that it is seated correctly

the handle is locked upright to ensure a good connection .between the tank and the rear cover gasket.

Check for any damage with the collection tank cap.

Check the divert knob is set to the tools setting.

Check the motor duct for suction (To locate, remove the water tank. .The motor duct has a rubber gasket that is oblong) with the power on, .place your hand over the hole for suction..

If there is still no suction, call BISSELL Consumer Services toll free .at 1-800-237-7691. A representative from Bissell will help you from there.

The suction for carpet cleaning is great but there is very little suction through the hose. I have cleaned out the hose but there is still very little suction. What else can I do?
ANSWER : Have you tried cleaning the hose from the vacuum end, the end that feeds the sweepings into the cannister/bag? Might be something close to that end of the hose..Also, one reason for a hose not to work is the possibility of a cut or broken hose or a loose connection..The closer an opening like this might be to the vacuum end of the hose, the less suction the unit will have through the hose as it will pull air through the hole/break easier than through the full length of the hose.

Hi my dyson dc18 has great suction from wand but when you got to use the vac for floors little suction but wand still got suction even while vacuming floors is it suposed to stop suction from wand
ANSWER : My Dyson dc18 had the same symptoms. The wand worked well and the floor bar had no suction. After removing pieces & shoving my fingers into the machine (no blockage) I found the suction pipe rotates between two positions (floor and wand). It looks like a piece of plastic broke on the outside housing, so it no longer rotates positions when the wheels are raised or lowered. My son found we can move the suction by sliding a finger into the mechanism behind the wheel cover, and rotating the plastic piece clock-wise or counter clock-wise until it locks into position. It’s a big pain but it works for now. I wish I could find a replacement piece online. Patty

Poor Suction Heya! So I just picked up a used Dyson, but when I vacuum with it, the suction is pretty weak and it spits all kinds of stuff out the back and into my feet. When I pull the hose I have good suction, but in regular mode it hardly picks up anything. The brushes are spinning, and it eventually will clean an area if I go over it again and again. Maybe a clog somewhere? Please tell me that Dysons have better suction than my $50 Dirt Devil! Thanks!
ANSWER : I recently bought a second hand Dyson DC07. Its suction was poor. I removed all the un-clipable pipe bits and to remove any blockage but it all looked clear. The Final Sponge and hepper filter did have a lot of dust in it and the rotating brush was full of hair but nothing bad.
.
.I eventual gave in to curiosity and removed the three screws in the top or the yellow removable dust collection tube and cyclone bit to see what was in there. The mechanism to release the flap at the bottom of the collection tube does not allow you to remove the lid completely but it does open far enough to get inside. I found the whole top section of the yellow plastic bit blocked by a big plug of compacted dust and a champagne cork. If you are willing to take the risk and have a torx 15 screwdriver handy it that part may be blocked. It did get a bit messy.
.
.If I was going to attempt the same procedure I’d remove the dust collection unit from the vacuum cleaner as I did before, but leave the clear tube attached and the emptying flap firmly closed to reduce the mess from the dust falling out the bottom while cleaning the top part.

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
