My bissell velocity height adjustment doesnt work

If the height adjustment on your Bissell PowerForce Helix Turbo Rewind vacuum is not functioning properly, there are a few things you can try to fix it:

1. Make sure that the height adjustment lever is being pressed down all the way. Sometimes the lever can get stuck in the "up" position, which prevents the height adjustment from working.
2. Check the height adjustment mechanism to make sure it is not damaged or obstructed. This may involve removing the vacuum's dustbin or base plate to access the mechanism.
3. If the height adjustment lever and mechanism are functioning properly, the problem could be with the vacuum's belt. The belt is responsible for driving the height adjustment mechanism, and if it is stretched or damaged, it may not be able to move the mechanism properly. In this case, you may need to replace the belt.
4. If none of these solutions fix the problem, the vacuum's internal hardware may be faulty and will need to be repaired or replaced. You may need to seek the assistance of a professional for this type of repair.

The adjustable knob is at the front of the vacuum with 5 settings from bare floor to high carpet.

there is likely a broken cam inside.replace it

Hi Chris! Lock the vacuum in the upright position, set the height adjustment to the desired setting, then recline the handle for the change to be made.
If you continue having difficulty, you may want to have one of our Authorized Service Centers inspect your vacuum.

Hey, not having a working height adjustment can be a bear. Lock the vacuum in the upright position, change the knob to desired setting, and recline the handle for adjustment to occur.

If you are still having difficulty, you may want to have your vacuum inspected by a Qualified Technician at one of our Authorized Service Centers. Here's a quick link to assist you in locating one.

sumthing is blocking the suction....

The height adjustment wont engage unless the handle is in the down position. Not knowing this led me to overturn the hight adjustment knob.

Step on the handle release, pull the handle back and lay the vac on its side. Then you can get the knob and the plate back together again.

BTW, the reason I had this problem is because the front brush slows dramatically when using on carpet, I thought it was set too low, and turned the knob (in a manly fashion, putting it past its limit). Still working on that one. After inspecting the belt, looks like one worn and cracked spot gumming up the works.

The handle adjustment knob part # is 2031095, the height adjustment wheel asm. part # is 2031330. You might try bissell.com and see if you can order direct from them. If not, most repair shops should be able to order for you.
