it does not working & I received cleaner head but brush does not working

I find the roller does not work.

I remove the roller and then it does work very well.

The connection part of the roller is broken.

I need to roller.

it does not working & I received cleaner head but brush does not working

 

When I connected the brush from the last video, the vacuum cleaner stopped working.

but You paid me $ 13 for shipping and only sent the head of the cleaner. You should have sent the brush together.

So I still can not use the vacuum cleaner.
