Eureka lightforce 300 poor suction, power paw doesn't spin and self cleaning duster doesn't clean its self when the button is depressed.

Eureka 4718AVZ LightForce 300 Bagless Upright Vacuum\015 Purchased new a couple years back. Hasn't worked properly since we bought it and has been sitting idle. My hubby isn't one to follow through with things and I simply haven't had the time to take care of it since he lost the receipt, otherwise it would have been returned and exchanged. It has never had enough suction to make the power paw spin and the self cleaning duster's fibers only vaguely move on the top 1/10th when the button to clean is depressed. I have brought it over to my Mom's and hooked up the power paw to her 12 amp vac and it works like a charm, I also hooked up the hose of my Mom's 12 amp vac to my lightforce 300's self cleaning duster and depressed the button to see what it would do…. the entire duster spun in the cleaner and the fibers were cleaned like it was a whirlwind vortex inside there….. So…. Help me out here and let me know how I can fix this ******'s lack of sucking power…...Thanks so much ahead of time for any and all help!\015

How to Identify and Fix Common Vacuum Problems ?

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

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.

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.

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.

Most cases of a jammed or stuck brush bar are quick and easy to fix, simply pulling the debris gently from the brush bar. Alternatively, if you need to clear a problematic blockage, you can take the brush bar out of the housing easily, for quick maintenance.

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.

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 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.

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.

Clear the brush roll of any hair and debris and inspect by placing it on its end and spin. The brush should spin freely. If it doesn`t spin; it may be time to replace.

If all you hear from the vacuum unit is a click at the when you try to start the vacuum motor from inside the house, then the motor in the unit is dead and has to be replaced. A strong odor from the shellac, which coats the copper coil windings, is an indicator that the motor is about to or has burnt out.

Founded in 1909 in Detroit, Michigan Eureka vacuums have been in American`s homes for more than a century. Now we`re building on that experience with innovative cleaning technology to help you clean for years to come.

The roller brush is the combination of a belt, a roller, and sometimes a small vacuum head motor. The roller spins, and the bristles attached to it sweep up debris that then gets sucked into the dirt container of the vacuum. The brush head also helps to pull dirt and debris out of carpets of various pile heights.

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.

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. That can often do the trick.

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.

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.

Replace the Brush Belt

If the vacuum is still hard to push, tilt it back far enough that you can inspect the moving brush while the vacuum is running. Be careful to avoid getting too close to the moving parts. If you see that the brush is not turning, that means you will need to replace the brush belt.

Any negative pressure significantly below standard atmospheric pressure (760 Torr/mmHg, 29.9 inHg or 14.7 PSI) is considered a vacuum.

If your agitator doesn`t spin when the machine is running, the belt could be stretched or broken. Here`s how to find out: Making sure your vacuum is unplugged, turn the power head over and attempt to spin the agitator by hand. If the agitator spins freely without resistance, the belt is broken and needs to be replaced.

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*.

If you checked your brush roll, floor setting, and belt but your brush roll is still not spinning, that means you probably need a Shark micro switch replacement. This small switch tells the vacuums brush when to start spinning.

Eureka lightforce 300 poor suction, power paw doesn’t spin and self cleaning duster doesn’t clean its self when the button is depressed.

ANSWER : When this happens to me I do two things. The first is to empty the cannister but when you do (with the vacuum unplugged) stick your hand up inside of where the cannister goes.Sometimes that is filled with debris. Pull as much as you can out. There is another part inside there that you can twist and pull out – this will help you pull out more of the trapped debris. Replace that part and the cannister – usually there’s a blockage and just removing some of that debris will cause a bunch more to dump in to the cannister. You may have to repeat this process two or 3 times untill no more debris comes out when you turn the vacuum back on.

The second tip solution is to clean the filter which can be found on the front of the vacuum.There’s a clear plastic cover, a black rectangular this that hold the filter sponge and inside of that, the filter sponge. I just rinse the little sponge inside and shake off the thing that holds the sponge (Sorry, don’t know the technical terms). Put it back together and you should have suction – viola.

Hope this helps.

Poor suction The actual sweeper seems to work ok, but the hose attachment has some suction but not enough to pick up things I think it should and not enough to make the power brush spin. I’ve checked everywhere I can for clogs, but I can’t see anything. And there doesn’t seem to be any way to check to hose itself for clogs. I’ve cleaned out the container and the filters, but there’s still a problem.

ANSWER : Check the inlet down by the brush roll, make sure it is open, if it is then the hose itself must have a clog. If the hose comes off, drop something like a marble in one end and see it it comes out the other end, if it doesn’t then you have a clog.

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.

I have excellent suction power through the vac, but when I try to use the hose there is no suction power there. I have cleaned everything and it is definitely clean and clear. I’ve also used the reset button.

ANSWER : When you use the upright Dyson, the handle has to be in the upright position for the hose to work. In this position, there should be a clear way through for the suction to the hose, and the suction for the normal sweeper should be off. This is all very mechanical, not electronic, and if it does not work there is either a blockage in a bit you haven’t found, or a broken plasic component which should be obvious if you take out all the bits in the pipe run that can be removed – there are quite a few of them!
Hope this helps

I have a DC07 and the brush wasn’t rotating and I had no suction at the brush but perfect suction through the hose. I noticed a large build up of dog hair around the brush so I took off the cover plate and removed all the hair, cleaned inside the floor/brush housing and cleaned out the hose. I also cleaned the filter and removed the other air access cover and made sure that they were clear. I put everything back and the brush still doesn’t turn and there is still no suction through the bottom

My Eureka/The Boss doesn’t seem to have the suction power it had. However, when I place my hand under the hose, it has good suction, then when I try to pull in a small particle, it doesn’t, unless I have the hose nozzle completely over the particle. The vac is 10 yrs. old. I cleaned everything. Someone said the belt. Would the belt matter if the hose doesn’t **** well? It is just old and worn out? It did shut off recently do to overheating. Help. Thanks. Lorraine

ANSWER : Doesn’t “The Boss” Vacuum have a filter? Perhaps your filter is clogged and not allowing it to work properly.

Suction button Although my Hoover Spin scrub is working perfecting dispensing the solution, when I go to suck up the solution from the carpet–I am having problems with the RED suction button that keeps popping up. I have to stop the cleaner and lift up the dirty water container to break the suction. Ive tried cleaning the netting that is encased around it, but still no luck.

Any help would be appreciated! Thanks

ANSWER : This happens when the filter on the inside of the lid for the dirty water tank is pushed all of the way up. You need to leave a 1/4 in. gap from the top to the top of the filter
