How to Identify and Fix Common Vacuum Problems ?

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

This usually occurs if the dust cannister is too full or the filters are clogged and the motor wasn`t getting enough cooling air passing over it.
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.

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.
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.
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.
There may be debris wrapped around the roller that is preventing it from turning. This is often due to hair, string, or other larger items that may be suck in the roller. Open the brushroll garage by sliding both of the release buttons away from you and then lift off the garage door.
Next to the motor, the belt on your vacuum is just about the most important part of your vacuum. Without the belt to spin the brushroll, most vacuums won`t pick up on carpeting at all! If your vacuum uses a rubber belt, check it once a month for cracks, melting, and especially, slippage.
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.
Twist the lid until the arrows line up and open up the container to get to the hepa filter. Take the filter out and brush the dirt out, once a month wash the filter in warm water. Please make sure it is thoroughly dry before popping it back in – this may take around 24 hours.
The most common problems found in vacuum cleaners are low suction force, excessive noise, burning smell, vacuum not turn on, and overheating. These issues can be fixed by either cleaning the device or replacing some parts of the device. At times, it is best to seek a professional to fix the cleaner effectively.
If this appliance also appears to have no power, there is possibly a problem with the supply at that socket. Check the socket is switched on and that there is not an isolator switch somewhere in your home which may be switched off or tripped out. If there is an isolator or fuse box, check it is also switched on.

I was vacuuming my room and all of a sudden I hear this loud noise, then notice the roller brush isn’t spinning. Thinking too much hair was caught I separated it from the rod and hose to clean it out, but noticed that the roller brush didn’t move at all while I was cleaning it. I’ve cleaned the brush before and it would roll around with little effort, but this time I couldn’t move it at all. After removing hair and string I put the vacuum back together and started it up, but the noise continued,
ANSWER : It sounds like if the rod is clean then there is debree inside the roller where the rod fits in too.

The vacuum is making a noise like something is stuck when it is in the carpet position but not when in the floor position. I can’t find anything that is stuck in the areas that I can see. I have cleaned the brush but it does not seem to want to turn. Does this machine need to be oiled so the roller will turn? Is there a way to check inside the motor? Do you think that because the brush won’t turn that is making the noise? Do you know of any repair shops in the Lake Havasu City, Arizona area?
ANSWER : As far as the roller brush goes, yes, it does need to be cleaned. Follow the directions to remove it and clean as best you can of all debris. On both ends of the roller brush there will be two “holders” of sort that connect the brush to the frame of the vacuum. These need to be able to turn freely around the brush. Clean them as best you can and spray some WD40 in between the roller and both the holders. Work the holders around by hand to be sure they move freely..I would also check to see if your belts are snug..

Roomba Discovery My Roomba turns on and moves but the brushes won’t turn. Someone told me that I had forgotten to put in the yellow and black end bearings, but I did. Help, I miss my Roomba
I have a Roomba 530, I have had it for 2 weeks and really loved it. I have followed all the cleaning instructions etc.. Then the Roomba wanted it’s brushes cleaning “please clean Roombas brushes” So thinking that something was stuck I removed and cleaned the brushes, (yellow tabs on and in place by the way)
ANSWER : I read somewhere that you need to clear the software in case there is a glitch. To do this, take the battery out and then, simultaneously hold down the “spot” and “clean” buttons for 30 seconds. Replace battery. This has worked for my Discovery model.

My brush roller stopped spinning so I had to take it off and clean out all the hair that had gotten wound around it. I replaces it and now it is make a lound noise, but only when the brush is on. Could it be the belt making such a loud sound? It wasn’t making this noise before.
ANSWER : Could very well be the belt..When cleaning the brush it is a good idea to add some WD40 at the ends where the plastic pieces are that hold the brush in the vacuum. The brush needs to be able to move freely around the plastic pieces..Add the WD40 and rotate the plastic pieces around the brush until they move freely..Reassemble making sure the belt is put in correctly so the brush moves in the right direction..

Dc17 -too much pet hair around the belt gears
ANSWER : I was having the same trouble and it was driving me nuts.  I tried cleaning and it did not work.  Then I tore the brush assembly off and looked up into where the little tooth gear is.  I saw something that did not look right.  There was a silver roller bearing laying down below the assembly.  I got some tweezers and found it was not attached to any thing.  I then cleaned out the pet hair and saw a spot where this roller goes that takes the slack out of the brush. It is a pain and takes alot of trying with pliers and prodding  with a screw driver, but I got the roller back where it goes.  It does not attach very solidly, but I put every thing back together and it works great so far.  It is a definite design flaw.  I found that you have to keep the main unit on  the floor when the brush is running.  Do not do stairs or pick it up and do couch cushions, that is when the bearing breaks loose.  Dyson needs to figure out a better design for this.  I was lucky to figure it out, but it is very hard to get to.  Again never pick up the unit when the brushes are engaged.

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
