Bought a new sweeper and brush ( beater bar ) does not turn. The large belt is fine and turns. The small thin belt is also fine but does not turn the brush. It is either the wrong belt or is there something that could be missing to put tension on it ?? Thank You [email protected]


Jim, To put tension on the brush, tilt machine forward when upright, move carpet selector knob to carpet. then turn vac on.

Brush Roll belt stops turning durring vacuuming on WindTunnel self-propelled, v belt is a little loose with handle down. Tensioning roll is engaged OK, but fully at the end of its travel. Replaced belts flat and v, but still stops turning even on high carpet setting when vacuuming. Carpet setting and height adjustment appears to be working OK, roll is clean and turns easily when out. Also turns easily until it engages the carpet. Self propel function works just fine.

Hoover Windtunnel U5750-900 Agitator brush is weak. It turns fine if I tilt the vacuum back, but it slows to almost 1/4 speed when it touches carpet, even on the highest carpet setting. I've replaced the agitator belt twice. The brush used to turn powerfully even on the lowest (Hard Floor) setting. Ideas? I should probably lube the agitator brush ball bearings, and re-check the belt, but, other than that, I'm stumped.

In my (almost new) Dyson DC31 Animal the rolling brush tends to stop like the bearing was kind of difficult to turn. I opened the side carter and removed the little belt. Without the belt the engine runs regularly. I cleaned the little knots of hairs trapped in the bearing but still the brush runs for a while then stops, tries for a bit then stops again. I even tryed putting a bit of synthetic lubricant with apparently no result. Could it be a defective bearing? Thanks for your help.

Hi,My agitator brush won't run on my hoover S3590, I changed the belt, that didn't work. I don't see a possible cause in my book except replacing the belt. I think there could be a short, the brush will come on sometimes when pulling back and slightly lifting. Any ideas would be great and can I fix it myself? Thank you for any help, Bobbie


Hi Bobbie\015\012Take apart the electro floor head if you can and inspect inside - it may well be that there's clogged dust preventing the brush from turning and also check both sides of the actual beater bar as thread and tangled hair can often lead ... Hoover S3590 Bagged Canister Vacuum

There is a shaft that comes out of the pump of my Bissell 1623-1 Power Steamer with gears on it. The belt to the brush attaches to it. When I went to change the belt, the belt was fine but the gear itself with the small shaft on it was no longer attached and just dropped out. It looks like there might have been a bushing there, but no more. Any ideas?

My Bissell 9200 is not sucking the water into the dirty water resevoir. 1. The gasket on the clear-view seems fine. 2. The suction power just doesn't seem powerful enough (feeling with my hand). 3. The brushes turn fine and belt is fine (not sure if that even matters for this issue). Any help appreciated. Thanks, - Matt

I have a Bissell pet hair eraser model #3920. It's been working great until last night. I went to use it and the brush won't spin. It also smells like it's burning. I checked the belt and it looks fine, and the brush spins by hand easily. It's not clogged anywhere that I can see. Anyone have any other ideas? This vacuum is only 8 months old.

Hi, i have a panasonic eco max, the brush has stopped going round, the belt is as new and brushes clean.suction good from hose. Any ideas please? thank you


The brush on this model is controlled by the on/carpet/floor switch and will only work in the carpet position. If the suction motor is running then it could be the roller brush motor, but it's more likely to be the microswitch which stops the ... Panasonic Mc-Ul594 Eco Max - Bagless Upright Cleaner

I have a Filter Queen Majestic 360 and am having problems with the powerhead. There is a loud rattling noise in the powerhead, especially when I vacuum thicker carpet. I have replaced the motor, roller brush, and belt, but the rattling remains. It sounds like it is coming from the roller brush area,and when I turn the powerhead over, it rolls free and sounds fine. Any thoughts?


Hi there, as per your information i guess its a problem of power transformer. He can't supply the proper power in the motor & thats why the noise will come from the transformer. Thanks & waiting for your feedback. ... Filter Queen Majestic Canister Vacuum

Hello. I have an electrolux glider upright bagless vacuum cleaner (UK model) who's brushes do not rotate any more. I'm guessing that I need to replace the drive belt but I have no idea where to start. I would appreciate any tips. thanks


Hello! There are two solutions to this as the Glider model you speak of could be the more old fashioned type where screws on the bottom foot plate (ie where the spinning brush sits) have to be undone in order to get to the drive belt.\015\012 ... Electrolux Vacuums

My Kenmore canister model (116) 26212601 works in hard-surface mode (basic suction), but the brush won't spin for carpets, and when I try to turn it on, it makes a whiny sound and then turns off as it does when I need to press the overload button. I looked inside a bit, and the belt isn't broken--it seems fine. So not sure what the problem is. Thanks for any help.

No action Hi: My brush roll won't budge. After we cleaned out all the hoses and replaced a badly worn belt (burned?) when I turn it on the smell of burning rubber and smoke has continued. What hurts is that I don't think I've used the vacuum a total of 10 times ... and I had such high hopes. Ideas?


I had the same problem with the belt breaking and the roller not spinning. I read about giving the roller a couple of revolutions to seat the belt, so I put another new belt on. It still didn't spin. I realized it was the end cap that was not spinnin ... Eureka 2961AVZ Bagless Upright Vacuum

My Kirby 2HD has started making an odd roaring noise but still works fine. I have taken the front assembly off and cleaned and adjusted the roller and checked the belt. The noise seems to come from the motor housing. I have tried to wiggle the main shaft at the front (bearings?) and it seems tight. Can't seem to get the other housings apart. Any ideas? Thanks, John


It is quite possible, it just needs lubed. The motor comes in direct contact with dirt so, you have to make sure the front bearing has a drop of oil on it from time to time. If it starts to scream at you within one month, after oiling, the bearing ... Kirby Heritage II Vacuum
