How to Identify and Fix Common Vacuum Problems ?

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

The most common cause of loss of suction is that the filters have become blocked. They may require cleaning or replacing. Another cause could be that the vacuum cleaner hose is blocked.
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.
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.

Often when your machine is not picking up it is due to loss of suction. If your vacuum cleaner turns on but won`t pick up on carpet or bare floors, something is impeding suction. You may need to change the vacuum bag, unclog the hose, replace/clean the filters, replace the hose, change the belt, or repair the motor.
Clog located in the vacuum hose

Turn the unit on and feel the suction at the end of the hose handle. If there is no or low suction, then the clog is in the hose. You can remove the clog by running a long, stiff object through the hose, such as a butter knife, starting at the wall end.

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.
Inspecting the Vacuum Commutator for Motor Brush Problems

Test that by turning the motor off and pushing on the center shaft, the armature. If it has any play, besides spinning, then replace the motor. If solid then replace the brushes – motor brush replacement instructions.

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.
Any good vacuum—upright or canister, corded or cordless—will do an excellent job of picking up pet hair, on both hard floors and carpets. We`ve tested all these styles, using bagfuls of genuine cat and dog hair, and all our picks have excelled at the task.
1. Motorized Brush Head. Sometimes called the “power nozzle,” this large attachment has a rotating brush to clean carpets more like an upright.

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.

Hoover WindTunnel Self-Propelled V Belt
ANSWER : I had this same problem with the V belt on my Hoover Vaccuum..
.There are three (3) basic things that will cause the brush roll not to spin..
.1. When handle is upright, brush roll is OFF..2. When switch is set for HARD surface, brush roll is OFF..3. Broken/worn FLAT belt or V Belt, brush roll will not spin.
.
.I noticed that the brush roll was not spinning when my vacuum was set for CARPET. After removing the cover I noticed that the V belt was loose, I thought the belt was worn so I purchased a correct replacement belt and installed it, but the new belt was also loose and when I turned the large flat belt pulley it did not turn the V belt pulley at the same time..
.I double checked the surface setting and I had the vacuum switch set for carpet, but still when I released the handle out of the upright position the brush roll would still not spin..
.My aggravation finally led me to this posting on FixYa’s website..
.The first thing I did was checked the screw to the left of the V belt as suggested by ejmjr5 and this did nothing to solve the problem or create more tension on the V belt, even when the upright handle was not in the upright position..
.After playing around with the surface setting control switch/nob I notice that when I moved the switch out of the HARD surface setting and over to CARPET, I had thought that the switch was set for CARPET as it visually appeared, but I was not pushing the switch over hard enough to click it into the CARPET setting mode..
.VOILA, the brush roll now spins correctly even though the V belt seams to be too loose for the pulley..
.You really have to force the switch into the CARPET setting. Be sure that you hear the switch/nob click into place..
.Now you can effectively clean up after that hangover of a party!.
.Burp!

We have a Hoover upright vacuum cleaner, model Core 7. There is a switch that turns on and off the brush drive. This operates via a cam with a bearing putting pressure on the final drive belt to engage the brush head.

My brush head is not turning and with the lever set to engage the drive there is still considerable slack in the final drive belt.

There appears to be only a bearing deflecting the belt, should there be a pully or other device mounted on this bearing? There is so much slack a

ANSWER : Yes, there should have been a white plastic sprocket on top of the bearing – in its channel the belt would sit. Unfortunately no parts are available for this unit that can be bought retail – only available by order to dealer repair shops....
Unfortunately to fix it you must send it to one and that would be more expensive than a new one. Just junk this chinese POS and buy another chinese POS.

Hoover windtunnel t series belt is loose- roller brush doesnt turn.
Its brand new belt is slipping. we bough new belts and putthem on same problem. Can not find solutio in manual.
Is the belt supposed to go around the “metal pulley”. I know it goes around the little metal motor thing, then thru the guide and around the brush.
What is the metal pulley??? Is is the larger round silver thing between the guide and roller?
ANSWER : I also have a loose belt and have bought additional belts but have the same problem. I put the it around the metal rotor and around the brush roller a shown by he Hoover video, and it is loose.

My Hoover Windtunnel Mach 6.9 brush roller quit working. Upon investigating I found that the idler arm pulley was broken so I managed to replace that. Before putting the cover back on I see the control knob for the roller brush moves a plastic piece left or right to activate/deactivate the brush roller. I don't know where this plastic piece connects. It appears to me that the idler are when raised creates tension on the belt which drives the roller. I'm at a loss trying to figure ou

My Dyson Animal has good suction and works fine for actually picking up dirt, but when I use the vacuum with the roller, I hear a grinding/rumbling noise. Its only when I use the vacuum with the brush rotating. It does not happen hen I shut the roller brush off. The belt is fine. I cannot figure out what is wrong as there are no clogs, debris, or foreign objects stuck in the brush or in the belt. The noise seems to be the only issue. The vacuum picks up fine. It just doesn’t sound right a
ANSWER : Trace the path of the suction into the tank and see if there is anything loose or ingested..Also, remove the brush and clean as best you can. Perhaps there is something caught in it. Lubricate where it makes sense with some WD40.

I’m using (or WAS using) a Eureka ”the boss” model 8803. The belt broke, no biggie, so I replaced it with a Eureka model U belt, the problem is when I put the new belt on and turn on the vaccuum, the belt breaks again. I am also having trouble getting the brush roller to fit right when the belt is in place. I can’t find any sharp edges that would cut the belt,nor can I find where any small bits may have broken. Anyone have a solution for me?
ANSWER : First, make sure you have the right belt, second, i am thinking that you are not lineing the roller up right, it will only fit one way. look at the ends of the roller and the grooves where it slides in, you should be able to see clearly how it goes.
