I wouldn't count on it doing much actual grooming. I know mine wold like
chewing on it however.

I have one & my cats use it - always has some hair in its bristles.  OTOH,
my cats only rub along it from the outside - they don't walk under the arch.

I screwed a natural bristle scrub brush onto the vertical low side of my desk
and my cat likes to brush on that, but not enough to be called good grooming.He
used to rub on my desk anyway so I thought I'd put that there for him. He likes
to rub his face on it.

It is impossible to say if it will work for your cat.  I did buy one
for Princess (RB) and she would not use it .  I have tried the corner
gadget too -- would not use.  The best grooming gadget is  me.   MLB

I had one. Tucker would not use it. We also have one at the humane
society where I volunteer. A few of the cats will rub on it now and
then, but most of them ignore it.

I have something similar, although mine looks much nicer than the picture in
your link.  The brush is much fuller/thicker and I think it's made of sisal.
The base is also covered in sisal, not carpet.  When I first got it Tiger
loved it.  She would mostly stand on the outside of the arch and rub against
it.  She still uses it occasionally, but mostly likes to sleep on the base
rather than use it for grooming.
