<!-- from fixya rte -->Ow do I know if a vacuum belt has gone bad - Shark Professional Pet Navigator Lift Away Bagless Vacuum

It may have a bad clutch belt. When the belt on the clutch begins to slip it makes a terrible noise. If the noise is gone when the brush roll is off you will have to take it to a dealer.

Hello Jeannette, you unit probably needs a system maintenance. Their are quite a number of possible problems affecting your unit.The belt could have cut thereby not rolling the motor, the motor could have become bad and the control board could have gone bad. Although apparently since the light still comes on this indicates that the power is still supplied into the unit. trouble shooting tips for vacuums differ what is the exact make and model of your unit? Let me know this so i can provide more exact answers for your problem.
Hoping to hear from you soon.
Thank you for visiting FixYa.

It sounds like your roller brush itself might be bad. Try holding the roller brush holding just the end caps with your finger tips, and spinning the roller. Does the roller spin freely? If no, this indicates that your roller brush's bearings have melted together. This is a common problem for Bissell vacuums, as they use cheaper plastic bearing caps. The roller brush is not covered under the warranty either.

When this part goes bad, this causes the belt to break almost immediately. If you tried replacing the belt, and it broke immediately, your roller brush has gone bad.

sounds like the brushroll motor has gone bad. disassemble the head and check the continuity on the brushroll motor

It might be a simple as changing the clutch belt and the drive belt and cleaning out the brush roll. You can get replacement belts here:

Greetings from GoVacuum,

I believe what may have happened is that your vacuum cleaner belt has either broken, or been stretched so far that ithe brushes are no longer spinning fast enough.

Here's what you should do to diagnose this problem.

1. Take the suction hose out of the back of the vacuum (assuming that your vacuum has on-board tools), and see if you have any suction coming from the hose. If you do, this indicates your belt is bad.

2. If you don't have suction coming from the hose, then it may be something as simple as replacing the filters, to a clog in the vacuum, or to your motor going bad.

In my professional opinion though I would say from what you stated that the belt is mostly likely going to be your issue. If you can provide me the model number of your vacuum cleaner, I can walk you through step by step on ow to replace the belt.

I have posted a short YouTube video on a vacuum belt change, this is not for all vacuums, but it will give you some idea of how to change a belt;





Thanks, and if you have questions about your particular model, please feel free to contact me at

Depending on the make and model the belt may be bad or if it has a clutch assembly then it has gone bad.

Your belt is probably broken. Check your belt and make sure your brushroll has not seized. If both of those check out ok, (because the smartvac belt doesn't stretch,) the belt tensioner assembly may have gone bad.

Trouble Shooting guide:

1. Check to make sure that your agitator still spins. (Agitator = brush). If your agitator does not spin, it could very well be a belt gone bad and means there will be no suction.

2. If belt is fine and agitator spin, your vacuum could be clogged. A clogged vacuum can be cleaned with a brush inserted into the hose of the vacuum to pull out the debris.

Burnt smell is probably the belt slipping. Even though it looks OK, either the belt needs replacement and/or the roller needs cleaning and/or lubrication at the ends. Try cleaning the roller ends first and then light lubrication with WD40. If belt works, you are done. If not, replace belt.
