Home Improvement

I know this is a cleaning request than a home improvement one, but I would appreciate some advice.

Some months back I moved into a place where the only carpet is located on a staircase. The carpet is thick and maybe considered to be medium to high pile??

The entire time I've lived here, I've struggled to figure out how to clean the damn stairs. The carpeting seems to be a magnet for every particle of dirt and strand of hair.

I have a full size vacuum with a hose. The hose doesn't actually seem to vacuum up anything from the stairs and the main part of the vacuum is too large to use. So the vacuum does fuck all for it.

I'm thinking I maybe need to use something like a wire bristle brush and a lint roller to actually remove dirt and hair??? Is there a best methodology for something like this?

Also of note...I was gifted a Bissell Crosswave recently. It doesn't seem like it would work well on thick carpeting, but I'm wondering if there's a technique where I could maybe use it for that???

I appreciate any advice! Thanks!
