Eureka 2971AV EZ Kleen Bagless Upright Vacuum\015 I just purchased a used Eureka Spinduster vacuum model 2981. The suction on the wand attachment is very good, but the vacuum itself has pretty poor suction. I can see the power brush spinning until I lower the vacuum cleaner, and then it just kind of twirls. I’ve tried changing the height, but it still isn’t spinning well. Do you have any suggestions?Thanks,Becky\015

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.

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 air filter traps particles as the air travels through the vacuum cleaner. If the filter is clogged, the vacuum cleaner will not have proper suction. If your vacuum filter is clogged, refer to your owner`s manual for cleaning instructions.
Suction pressure should be kept at less than 200 mmHg in adults. It should be set at 80 mmHg to 120 mmHg in neonates.
Air watts are a European test standard (IEC60312) for vacuums. An upright vacuum cleaner should be around 100 air watts and a cylinder vacuum cleaner needs to be about 220 air watts.
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.
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.
Over time and extended use, a very fine layer of particles will start to line the inside of a vacuum bag, remaining in place even after the bag is emptied. This means that the bag will lose the proper airflow required to let the incoming air escape. As the airflow is restricted, the suction dies down too.
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.
Putting in the incorrect amount of oil, putting in the wrong type of oil, and oil contamination can all cause the pump to not reach full vacuum. For this reason, you must check the oil regularly to ensure that it is not only clean, but also properly filled.
To reset the thermostat, press the vacuum`s power button into off position and unplug the vacuum. Check the vacuum for potential causes of overheating, such as clogs or a full dust cup, and allow the vacuum to set and cool off for 30 minutes before turning it back on.
Some GI suction regulators can provide full line vacuum; others have a range of 0 to 120 mm Hg or 200 mm Hg. Thoracic suction regulators provide lower vacuum pressures than other types do, generally in the range of 0 to 45 mm Hg and 0 to 60 cm H2O.
Suction pressure is always measured by the amount of pressure below atmospheric pressure e.g. a suction pressure of 100 mbar means 100 mbar below the atmospheric air pressire. Vacuum pressure is similar but should be referred to perfect vacuum e.g. a vacuum of 100 mbar means 100 mbar above a perfect vacuum.
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.
Suction pressure, which is measures in kilopascals, is another great way to discern a vacuum`s power, although fewer manufacturers disclose this number. But if they do — look for a range of between 5 to 20 kilopascals.
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.
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.
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.

Low suction on Eureka spinduster vacuum cleaner
ANSWER : The belt has stretch enough so as to not drive the brush roll under load. Try a new belt.

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.

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.

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 sence in vacuuming old rotten carpet.or try using a vacuum without a brush roller and just suction

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 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 a Kenmore canister vacuum – model 25614506. Some time ago, I was not able to turn the vacuum off with the on/off switch, but could still use the vacuum. Turned if off/on by pulling the plug. The other day when I went to plug it in, I heard a pop. Now the sweeper runs but the vacuum cleaner does not **** – no air flow. What could be the problem. The cleaner is only 4 years old.
ANSWER : The motor has an inline fuse

Smell/suction I have a Eureka Altima Model 2991 Type AVZ. I have suction when I use the power paw and attachments. I have all hoses clear. My brush is spinning and belt is not broken (I opened it up and checked), but I have no suction when I turn it on to vacuum my living room carpet. I also have a burning smell to go with it after about 30 seconds. I’ve never had a problem with this vacuum cleaner before.
ANSWER : Ours started smelling too, and it seems that the plastic end on the roller brush was melting. In process of finding rollerbrush for it now
