How to Identify and Fix Common Vacuum Problems ?

There may be a blockage in the agitator brush roller located at the front of the bottom of the vacuum causing difficulty when pushing the vacuum. To check if the roller is stuck, follow this guide here.
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.
For a vacuum cleaner to glide easily on a carpet, air must flow into the nozzle and through the machine. Block the air flow and the vacuum seals itself to the carpet and is hard to push. And, unfortunately, that`s what many consumers have discovered when their new carpeting 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.
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.
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.
You may have stalled the brush motor. To reset, turn off and unplug, then plug back in and turn on. The brush roll may have lodged debris or other entanglements keeping the brush from rotating.
Suction too high

If the vacuum is hard to push, the suction could be too high. Make sure the power button is on the right setting for the respective surfaces. Position I is for bare floors and position II for carpets and rugs.

Vacuum cleaning is one of the household chores that may leave us with pain. That is because while using a vacuum cleaner, weight is transferred back and forth between the back and the front lower limbs. Vacuum cleaning also involves bending which indirectly puts pressure on the lower back.
While extreme suction power may offer peace of mind to homeowners who want to feel confident that their vacuums are effective at sucking up dirt and germs, it can be very damaging to your carpet and should be avoided! For high pile and premium soft carpet, be sure to avoid vacuums with concentrated or sealed suction.
In fact, vacuums are superior to mopping practices when it comes to your hardwood, because they suck up the debris and dirt straight away, rather than just spreading those scratch-causing particles around.
Suction too high

If the vacuum is hard to push, the suction could be too high. Make sure the power button is on the right setting for the respective surfaces. Position I is for bare floors and position II for carpets and rugs.

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.

We have two possible ways of adjusting the pressure in a vacuum system: first, by changing the pumping speed (altering the speed of the pump or throttling by closing a valve); second, through admission of gas (opening a valve).

My model F5906-900 — problem is the brushes have stoped working… I pulled the brush assembly out by holding the two tabs, and all seems clean and the brush assembly rotates easly… onced the brush assembly is removed. What I did notice is the female driver slot (found in the main assembly unit) that drives the brushes seems stuck..Is that normal when the machine is not hooked up to power? How can I get the brushed going??? it is a good machine, but the brush options is important too it’s ab
ANSWER : (1) Assure the Brush Control on the hood is NOT set to the OFF position.
.(2) Remove the brush assembly by pulling/unlatching it from base on each side.
.(3) Does one of the brushes have the drive pin present? It should be about ¼ inch square, and two inches long. It attaches the brushes to the drive mechanism.
.(4) Remove and clean the intake filter. One the base of the cleaner, behind the brushes, squeeze the two red abs together and pull the panel down to access the screen. Clean the hair/debris off the screen and reassemble.

Now that I just fixed my Lux Legacy canister vacuum, I need help on my other Electrolux Regency Series upright! The vacuum works fine but the rotating brush does not work and the brush motor does not turn on. Tried cleaning the brush and hitting hte reset button to no avail. This upright has a triple setting switch and I checked the each of the wires seem to be attached. Tried rotating the brush by hand and it would not budge. Was going to “encourage” the brush to turn with a set of articula
ANSWER : There are a couple rectangular holes on the bottom of the power nozzle, beside the wheels. These have tabs in them that need released with a standard screwdriver.
.rogerpotts_10.jpg.Once they release, turn the vacuum over and lift cover of power nozzle at the back. This pulls the front of the cover out of the lip on the “bumper”.
.Once this is done, you’ll need to unscrew the screw at each end of the brush. Lift the brush out and thoroughly clean it, including the ends.
. rogerpotts_9.jpg.
.Check the wiring to make sure they’re connected to the terminals of the motor. Also, check the belt for wear and tear. These belts can last for five years or more, but if it looks bad a good time to replace it is while you have the power head apart.
.When reassembling the vacuum, ensure the belt is fitted properly around the motor shaft and brush.
.Insert the front of the cover first, ensuring the edge fits neatly beneath the lip on the bumper all the way around. It takes a little manipulating to press the back into place. Make sure both tabs click into the locked position. Turn the vacuum over and reinstall screws. Try to rotate brush by hand a few times.
.At this point, plug the vacuum in and turn it on. If the power head doesn’t run, press the reset button. If the power head motor still doesn’t run, it could be due to loose or disconnected wires that lead to the reset switch, a bad reset switch, or even a bad motor. The vacuum needs to be taken to the nearest Aerus Electrolux store for further diagnosis and repair.

Dyson dc07 The rotating brush on the bottom of my vacuum was filled with strings. I removed the brush by undoing all yellow plastic screws from plate. Removed all strings and replaced as best I could and it was hard to get the brush back in and the belt around it. I dont have my manual but it fits so it should be correct….? Right? No, not true, because when I turn it on and try to and vacuum (by lower canister with foot release) it makes that terrible ratching sound). Please help
ANSWER : The loud ratching is a warning to tell you that there is something stopping the roller bar from rotating this is a very common thing lay the machine on the floor front side down take off the bottom plate and just check the belt is in the centre of the belt guide on the brush bar normally if you turn the roller slowly without the bottom plate fitted it will straighten out on its own

Stopped running My mother’s Oreck vacuum sound as if there was something bogging the rotating brush down. I pulled the bottom cover off and found nothing wrapped around or restricting the brush. I tried to finish vacuuming with the problem then I turned it off to move a chair and turned it back on it would do nothing. Any suggestions as to what could be causing the vacuum to sound as if the rotating brush is being restricted from turning. There was not odor of burning as if the motor was in a bi
ANSWER : Orecks have a plastic fan inside and everything you pick up hits it, sometimes things can get stuck in there or break the fan locking up the motor. With the machine off, poke around where the dirt goes into the motor, behind the roller and see if you can pull anything out.

It seems when i am vacuuming it is very hard it move and the brushes does not rotate after the rug strings got into it.
ANSWER : Your belt is stretched or worn and therefore cannot turn against the resistance of the carpet. If you replace the belt it will fix the problem. You can get the belt you need here:

Noise My Dyson DC08 is making a loud, rough, vibration/noise that seems to be coming from the from the rotating brush housing. I replaced the old belt which was several years old and slipping. When I run the motor with the new belt removed the machine sounds normal. The bearings on the rotating brush seem to be running smoothly when turned by hand both when out of the brush holder and when installed in the machine. I can’t find anything rubbing on the belt or rotating brush. I applied a bit o
