How to Identify and Fix Common Vacuum Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :
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.
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.
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.

You need to take the vacuum apart and clean thoroughly first.
Then get back to me.
.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!
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
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.
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?
