Extremely loud all of the sudden. - Bissell Cleanview Helix Vacuum

I will likely save money by having it checked out by your local Riccar service center. A Brilliance can last a long time and work great but like any quality vacuum should be properly serviced every year or two depending on use. A qualified service technician knows what to look for and what your vacuum needs to work properly.

I would need to hear the noise to make a guess what is causing it.

your fillter needs cleaning out

Mine too! Have you fixed the problem or just given up. It's so loud it sounds like a piece of shop machinery that requires ear protection!

It could be that the belt is worn. You can get replacement belts and the manual here:

Bought a new vacuum cleaner.

Thank you!

Mine started making a lot of noise and my husband noticed the brushroll was slightly bent. I have no idea how this happened, but I noticed several people online were having the same problem. I ordered a new brushroll and popped it in and solved the problem. The noise before I did this was horrible! It is now back to normal.

When I turn my vacuum
Posted by Danedinburgh on Apr 25, 2008
When I turn my vacuum cleaner on the noise of the motor is extremely loud. It is only about three months old and was never this loud. Any ideas?

Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure.
You probably have a broken fan or fan blade and it is need of replacement. I am un-sure of the brand name or model # but I feel you would need to contact your local vac dealer. So If you need further assistance, please feel free to contact your local vacuum cleaner dealer in your area or in the yellow pages, or contact the factory phone number or website to further assist you with your questions.
Thanks, Don – The Vac Man

That only happens to me if I leave the vacuum on the carpet and don't raise the head before 30 seconds...it is the rubber belt hanging on the metal thing that it sits on. Since the belt is not used with the hose attachment, I cannot imagine what is going on. Therefore, I've been no help at all! Just to let you know it happens to others - just slightly differently.

remove belt to brush roll and see if noise persists. if it stops, you probably need a brush roll. at least doing this will narrow down the fault area
