How to Identify and Fix Common Vacuum Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :
Should the brush not rotate freely there may be debris tangled around the ends of the brush, carefully remove any obstructions or replace the brush with a new one. We recommend that you fit a new belt and brush once per year to keep your Reactive vacuum working efficiently.
A carpet beater bar is essentially a floor nozzle for a vacuum equipped with a rotating beater bar that spins while the vacuum is in use. By spinning, it agitates the carpet and loosens any lead dust that might be stuck in carpet fibers.
Graphite is considered to have excellent lubricating properties where moisture (water vapor) is available since its shear strength is dependent on absorbed gases and at low (vacuum) levels, these gases desorb and the coefficient of friction dramatically rises.
A beater bar is a rotating brush that is typically found on upright vacuum cleaners. It is designed to agitate carpets and loosen dirt and debris, making it easier for the vacuum to pick up. The beater bar is usually located at the base of the vacuum and is powered by an electric motor.
If the roller brush is not spinning, it cannot pick up dust. One reason could be that the power button is not set to position II, which runs the roller brush. If the button does not work, here is the link to the power button replacement guide. Another reason is that the roller brush could be broken.
Almost every time that the brush stops turning, it is because of hair wrapped around the brush roller. You will burn out the belt if you use it too long in this mode. Your only fix is to take it apart and and clean it (and cut any hair stuck in it in the process).
1. Mineral Oil Lubricants. Mineral oil lubricants are the most common type of lubricant used for ball bearings. These lubricants are made from refined crude oil and are affordable, widely available, and effective in reducing friction.
Most wheel bearings require an NLGI 2 grade grease, while some sealed hub units require an NLGI 00 grade semi-fluid product. For those cases, the NLGI GC-LB or SAE J2695 consistency requirements do not apply. Each type is unique to the bearing design, and should not be used in the other type of bearing.
High Vacuum Grease is useful as a sealant and lubricant in a variety of general laboratory applications. Made of silicone.
Roller brush is not spinning
Check to make sure the vacuum is switched to the correct mode. The switch should be in the Power and Brushroll mode to make the roller spin. If it is in just the power mode the roller will not move. The brushroll indicator light should be green when working.
A vacuum cleaner`s brush roller also called the beater bar assists in cleaning your carpets and depending on your vacuum model, a variety of floors. The brush roller is usually located under the vacuum cleaner and some in the attachment tool.
Vacuums without beater bars operate similarly to those that do have beater bars. However, their functionality can vary slightly. In the strictest definition, a vacuum without a beater bar will lack one entirely. Many canister vacuums are designed without a beater bar, relying simply on a suction nozzle instead.
The two settings – brushes up and brushes down are to help you clean both carpets and hard floors. When the brushes are up you can get nice and close to carpeted floors and suck up all the dust and nasties hidden in the fibres.
A Revolving Brush Roll Greatly Enhances Carpet Cleaning
Vacuum cleaners specifically designed to clean carpeted floors have motor or turbine driven revolving brush rolls with rows of bristles and sometimes beater bars as well. These brush rolls revolve at a very high speed, agitating the carpet fibers in the process.
Brushes. According to iRobot, brushes should be replaced every 6-12 months. Robot vacuums like the iRobot Roomba j7+ have multiple brushes that allow it to clean.
The brush roll or its bearings may be clogged with hair, threads or dirt. Make sure they are clean and the roll spins. The belt may also have slipped because it was loose. Check the fit of the new belt when it is installed.
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.
Bearing oil lubricant is used chiefly when the heat has to be removed from the surface of the bearing under high speed or temperature conditions. Oil for bearings can be either petroleum-based or synthetic oils.
In general, both mineral oils and synthetic oils can be used for ball bearing lubrication. Synthetic oils are mainly used for high temperature fluctuations in the working process.
A common rule-of-thumb for roller bearings located in a bearing housing is to fill the bearing housing from one third to two thirds full of grease.
Dow Corning® High-Vacuum Grease is a stiff, nonmelting silicone lubricating material that maintains its consistency from -40 to 204°C (-40 to 400°F).
This means that despite very low pressures, the grease will remain intact and not vaporize, thereby coating all of the components within the system. For many applications, grease migration would contaminate the process or equipment within the system.
With the exception of top-of-the-line brands, most vacuum cleaners have a lifespan of about four to six years. While not all machines will need to be replaced after four years, it`s a good indication of when you may need to think about investing in a new one.
“We would recommend vacuuming at least once or twice a week—and more often if we have pets—with the right tools to remove dust quickly and effectively,” Patel advises.

I had a shoelace get stuck in the beater bar. I turned it off, tipped it over and untangled the shoelace from the beater bar. When I plugged it back in the vacuum ran but the beater bar was not turning and there wasn’t any suction. Is there a reset switch for the beater bar? Thank you for your help, Janet
ANSWER : Hi Janet. there is a small reset button on the outside of the head next to the brush that you can push to get it to start spinning again.

The beater bar on my Dyson won’t turn. The vacuum runs and suctions but the bar won’t turn and the belt is not broke. The beater bar did get a carpet fiber caught and wrapped around it which stopped the bar and I removed the bar to cut the fiber loose and replaced it and now it won’t turn
ANSWER : The belt doesn’t have to be broken to make the vacuum not work correctly. If the belt is stretched the vacuum won’t operate the way it is supposed to. You can get replacement Dyson Belts here:

I ran my vacuum against an area rug that has strings around it and a few strings got caught up in the beater bar. Now, the beater bar does not function- the motor runs but the beater bar does not seem to be operating. I removed the strings from the bar.
ANSWER : Hi,
.
.There is a switch next to the main power switch on the handle which turns the brushbar on and off. When the beater bar becomes obstructed as in your case, there is a safety feature which cuts power to the beater bar. All that needs to be done in most cases is to turn this switch off and back on again and the beater bar should resume operation.
.
.The beater bar on / off / reset switch is the yellow switch to the left of the main power button if you are standing in front of the hoover:
.
.
.
.
.
.Reset the beater bar and you should be back up and running.
.
.If you have already done this or it doesn’t solve your problem, please post back for further assistance.
.
.PLEASE NOTE: This reset method is for the Dyson DC17 ANIMAL as stated above. If you have a different version of the DC17, please post back for alternative instructions and state which version of DC17 you have.
.
.Hope this helps.

My beater bar makes a noise and has a crack in the motor on the beater bar and is discolored–me thinks I need a new motor for the beater bar
ANSWER : Sounds like you’re right. New motors are available at your nearest Aerus Electrolux store. They used to charge the same amount for selling the motor and letting the buyer install it, or for installing it in the shop. Worth checking in to.

My Dyson DC17 beater bar motor works intermittedly. I have to almost whack it on the floor to turn it on and then shuts off again. I have checked the belt and it is fine, also have checked for blockages. The switch to turn the beater bar on or off will not work when the beater bar motor is off. the suction is fine though.
ANSWER : Buy a Kenmore for less money

I have a dyson DC28 vacuum and the power button flashes on and off and the beater bar quit turning. I turned it over and found some string caught on the beater bar which I removed, but the beater bar still does’nt turn and the power button still flashes on and off. I hope you can give me a solution to this problem.
ANSWER : I had the same symptom with my wife’s DC28. The problem was associated with the cam driven height adjustment mechanism. The beater bar must rock freely up and down when pressing on the tabs that the end cam lobes actuate. On ours I found hair and crud jammed in between the end of the beater bar and the side of the vacuum head preventing it from moving freely. To clean it out I fashioned a hook tool by straightening a paper clip and bending the tip at 90*, then took a flat screwdriver to pry the gap open a bit so I could use my tool to clean out the buildup.
I removed the plate that holds the cam in place (6 torx screws) to gain access to the rocker tabs, although in hind sight I could have probably just left it in place. It doesn’t matter how you set the cam back into place. It’s self aligning with the aid of the micro-switches inside.
Hope this helps

I purchased a Eureka C4910 last year and have a question that I am hoping you can answer.
There are two motor actions with this vacuum, 1) the vacuum suction, and 2) the beater bar. The action of the beater bar is that motor is supposed to automatically shut off when the handle is in the complete vertical position assuming the vacuum is stationary, but then turn on when the handle is tilted toward the floor, assuming the vacuum is moving back and forth.
The beater bar motor turn-on mechan
ANSWER : Good day!
Normally when the motor is easily moved back and forth means that it have a proper lubrication,proper alignment and no clogs.
When the motor and the belt is OK the problem could be on electrical wiring and switch.
If found electrical switch burned out you need to replaced it because when the switch is burn the contact of that switch is open even you turn it ON.that’s why the motor is not function because the voltage is not pass through the circuit because of open switch.You need to replaced it.
And check some fuses if any and other burned electrical wire.Replaced it also.
Thank you and don’t forget to rate my answer.

Kirby Heritage II. Beater bar does not turn. One end rotates freely, but the other sticks, preventing the bar from rotating. No obvious means to disassemble the end of the bar. Is there a way to repair this, or does this require replacement of the beater bar? Did clean the front end assembly, and removed all hair, threads and similar obstructions.
ANSWER : The bearing is bad on the end that turns hard. You will need to purchase a new brush roll assembly. If the roller is older that 4 or 5 years, it should be changed anyway. The brush strips that scrub the carpet loose their strength after many years of combing through the carpet, so it’s a good idea to change it every 5 years or so.
