Vacuum sounds like an airplane after 1 year of use.

It sounds like the small silver piece that fell out of your BISSELL Powerforce Helix may be the motor brush. The motor brush is a small, spring-loaded carbon block that makes contact with the motor to conduct electricity. If the motor brush falls out or is not installed correctly, it can cause the motor to make a loud, high-pitched noise.
To fix the problem, you should locate the motor brush and try to reinstall it. The motor brush is typically located near the motor on one or both sides of the vacuum. You may need to consult the user manual or contact BISSELL customer service for specific instructions on how to access and install the motor brush.
If the motor brush is damaged or missing, you may need to purchase a replacement motor brush from BISSELL or a vacuum repair shop. Once you have replaced the motor brush, the high-pitched noise should go away and the vacuum should operate normally.

Inspect the area around the brush roll. There may be something stuck somewhere in there. Remove the brush roll to see if the brush roll end caps will spin freely. If there is hair or debris restricting the brush roll may be causing noise.

My first guess is there is something caught in the pickup wheel.
1. remove the belt cover to access the pickup wheel
2. remove strings and hair around the ends
3. if you can, remove the belt and see if the noise goes away when you turn it on, this will help to isolate the problem
How old is the unit?
Does it pick up dirt good?
Describe the sound, clicking, rubbing, wheezing, bangin' or clangin'

more than likley its the motor bearings wearing out and the brush bearings as well by now

clean ALL the filters or buy new one it would be better to buy all new filters also check for clogs in the vacuum also check the belt if the belt is broken it will not pick up much 1. check all tubes for clogs if still dose not pick up 2.check the belt and replace if broken if it still dose not pick up 3.do the filters that worked on my bissell

the hose is clogged. try sucking the dirt out with another vacuum (backward) If this doesnt work, you will have to disconnedt one or the other or both ends of the hose to remove the clog. this is a simple process.

thanks for your interest in FixYa.com

belt need to be replace

i know bissell vacuums are very cheap but they should last more than 3 years. there should be two parts to the dirt cup. remove the dirt cup and above it there should be a round plastic part. unscrew it and check that filter.
