Loose connections will cause your vacuum cleaner to lose suction. Make sure that the dust container, the hose, the tube and the brush are all attached properly. If the problem continues, your vacuum cleaner might have a technical problem. If you suspect this to be the case, contact an authorised service agent.
Regardless of what type of vacuum cleaner is being used, all of these products have a motor to create the negative pressure, or suction, necessary to draw in the dust and debris.
The suction motor creates vacuum pressure and suction by rotating a motor fan. The impeller rotates at an incredibly high speed of about 30,000 to 35,000 RPM. A suction motor`s power is measured by multiplying the rate of air flow and the vacuum pressure, which induces air flow from the brush through the hose.
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.
Suction is the air pressure differential between areas. Removing air from a space results in a pressure differential. Suction pressure is therefore limited by external air pressure. Even a perfect vacuum cannot suck with more pressure than is available in the surrounding environment.
Suction Power
This is an indication of how good the vacuum cleaner is to clean – i.e. the work to be done. The suction power is measured in Watt (W) and is typically between 250 W and 450 W for machines with 1 motor.
While the Airflow measurement indicates how much air the central vacuum motor can move, the Suction measurement tells us the maximum pull the motor is capable of. This is determined by sucking a 2 inch column of water vertically to its maximum height in inches.
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.
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.
Common materials are NBR (Nitrile butadiene rubber), NR (Natural rubber), SIR (Silicone), FKM or FPM or Viton® (Fluoro rubber), PU (Polyurethane) are common in material list of vacuum suction cup. Proper selection of the right industrial suction cup depends on the industrial application and environment conditions.
(Inside Science) — A vacuum is a space absolutely devoid of matter, at least according to the Merriam-Webster dictionary.
Vacuum uses the surrounding atmosphere to create work force by pulling on, rather than pushing, a work piece. Evacuating air from a closed volume develops a pressure differential between the volume and the surrounding atmosphere.
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*.

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.

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.

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.

No suction i have a hoover supreme wind tunnel vac and its relatively new and the suction, well……sucks. It wont pick anything up! I am extremely frustrated! I picked up a ball of fuzz off the carpet and held it under the vacuum and it still wouldn’t **** it up. I then shoved the fuzz up INTO the vacuum. It fell right back out. I may as well not even vacuum. Please help!
ANSWER : I have found more vacuums on the way to the dump because they were full. Check. Is it full?
.If not the air way is clogged.

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:

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.

It has no suction. It was fine yesterday. I washed the dirt container and the filter, let it dry and put it back in the vacuum. Today my vacuum isnt picking up any dirt and has no suction. When I took the hose out of the back, it started blowing dust and dirt out but still no suction.
ANSWER : Look for a place where the vacuum line has to turn in a near 90 degree turn. It’s easy for it to get stopped up there.
