With just the products that came with this pool, no, you can't vacuum directly to the pump/filter. You'll need a hose and some sort of adapter. Unfortunately, that's a hassle with what's provided with the pool. The video linked below is for a skimmer installation.

Of course, that new sand filter as $200 or more so that's a factor.
