Question about Bissell 3920 Bagless Upright Vacuum

2 Answers

Brush will not spin any longer

I believe this is due to the height adjustment for the vaccum cleaner no longer functioning properly. This vaccum cleaner is 7 months old and not having a poroperly working vaccum cleaner is becoming a major problem, having a 2 year old and a 4 month old puppy. If this cannot be remedied me and my wife will never buy a bissell product again.

    I have the Bissell Pet Hair Eraser and I love it, however, yesterday I noticed that the bottom brush was sparatic with its spinning. I took off the bottom housing and there wasn't anything clogged, caked, or caught under there. The belt was in tact though. Any other suggestions?

    I have the same problem, and its due to the height adjustment knob not supprting the weight of the vaccum such that the brush is against the carpet and cant rotate.  Its a shame that these good machines are crippled by one piece of badly designed plastic knob.

Even though the belt may look okay it can still be stretched. If the belt is stretched then it will not turn against the resistance of the carpet. I would try changing the belt. You can get the belt for this model here:

If the brush won't spin at all, it's either the drive belt or the roller beater brush is clogged. Pet hair can quickly clog a vacuum. Turn the unit over and see if the brush will rotate by hand. If yes, it's probably the belt. Also look for debris and clear as much out as possible. You may have to remove the bottom plate and clean the bottom of the unit out. If you do have to go that far, it would be best to replace the drive belt and thoroughly clean the vacuum.

Body of sebo x4 automatic not rising or falling


This could be due to the brush roller being worn.

If the brush roller is worn, then the height sensor makes the vacuum head go down fully. There still isn't enough resistance to the brush, but there is nowhere else for the height adjustment to go, so it just stays there. If you look at the cleaning head from the side you should be able to see that it is fully down.

The brush roller light is supposed to come on, but in my experience, it might not.

The beater brush will no longer drive under a load on short pile carpet


Have you tried changing the height adjustment? There should be a knob or lever that allows you to adjust the height of the beater brush to accommodate different carpet lengths. Even with a new belt, the brush will not spin if the height is too low. Try adjusting it all the way up, then while it is running, adjust it down until there is some resistance. The beater brush should just barely scrape the top of your carpet.

My 1 Year Old Sebo X4 was lowering itself to hardwood floor with no air gap. Sebo Support agreed with my repair shop that a new (blue) brush roller would fix the problem by replacing the 'worn" brush (same...


No not quite. For a start, the stiff bristles on the blue roller can last a few years before requiring to be replaced.

The SEBO sensor wheel adjusts to the height required - unless of course the microchip board has been tampered with. If it hasn't been tampered with. If the central wheel is excessively dirty then it could be that the SEBO isn't lowering the height properly. However, the X series is great at cleaning hard floors in general - i it is not designed for the brush roll to fully hit the floor, thus as you suggest crushing the bristles. It is designed, as you recognise quite correctly to skid across a hard floor lightly as there is a squeegee rubber strip built in at the back of the roller bar that scoops all dirt into the central vacuum path. The front plate also lends this job. You are not being conned - however check that the rubber squeegee strip has not worn away - SEBO do sell the strips and they are easy to slide into via the press release door at the side of the brush roll.

If the SEBO has died then its a possibility that there is a microchip function that gone wrong it. Some more information would be good to know here as it could be a number of things such as the cord cables coming away at the handle.

check to make sure that the brush wheel turns freely ( without belt on ) -- if it does not turn freely then there could be hair or carpet strands twisted up on the ends of the wheel,, inspect and clean. also make sure that the wheel cartridge is sitting nicely in its mounting area,, ( again - make sure the wheel turns freely ). now if it is moving freely - then make sure the height adjustment on the vacume is set to the proper height for your carpet thickness,, it kinda sounds like the brush wheel is not turning because it has to much pressure on the floor.
so -- make sure wheel spins freely,replace the belt and adjust the height and then check the unit for proper operation.

I have windsor s12 vaccum this one have brush up light on


The windsor Sensor brush indicator light will come on when:

  • Something stuck in the brushroller
  • Brushroller is worn and needs replacement
  • height is wrong (indicates a problem with height adjustment)
  • a bad circut board/sensor
more than likely your brushroller just needs to be replaced, very common.

Kirby Ultimate won't clean carpet


when you install the hose connector it trips a switch that switches the vac motor into high speed because the vac path is longer using the hose. check the belt after you remove the front. make sure the direction of rotation is in the direction of belt travel stamped in the impeller. try adjusting the head height
