Why can we bring someone with HIV to undetectable levels, but we can't completely cure it?

I'm just a little confused on why we can get rid of a majority of the virus in someone but not all of it.

So HIV actually integrates into the genome of your T immune cells. Drugs can help kill any virus copies that escape these infected cells, thereby keeping it from spreading to more cells, but it doesn’t detect the virus DNA within these infected cells.
