Redneck Repair: "Free" Hoover ONE PWR Cordless Vacuum Cleaner That No Worky Good 

MIne's doing the same thing. The belt seems looser than yours. But that drive gear has lost its teeth. Will try your shrink tubing idea. What size did you use? very nice jury rig solution.

I’m having a similar issue with mine, however we stopped using it before the belt tore the gear up. We only used ours for around 3 months before this happened. It seems to be missing some sort of belt tensioner that I can only guess goes in that small rectangle under where the belt rides. And like you found Hoover doesn’t sell any parts for this. Really wanting to find a solution, but will definitely not be buying another Hoover after this

My brush roller is still working but there is that same noise coming from mine. There seems to be hair caught around the main centerfuge drive which I cannot get the screw out to clean (that thingy you had to use pliers on. I can't get the backing plate off either. UGH! My model is similar but is red, not blue.

Ssme things happened to mine.

Not a good design. The bearing constant clogs with hair as others have mentioned. The screw that you could not remove is backwards (right hand thread - turn it backwards from normal to loosen). It does not have to be tight - if you over tighten it that will lock up the brush (just like the wrapped up hair - the brush rotation keeps the screw from coming loose). We like the vacuum but every other use the bearing needs to be cleaned - terrible design for a “pet vaccuum” - if you can avoid long hair that wraps up the brush bearing it works well.
