OK. Here's the REAL seller on the P/B. You can vacuum your entire pool with it, the battery (when it's good) will run for an hour or more. It's head is as big as a vac's so the surface area is good. It's FAR faster to set up than a hose vac and FAR easier to manuever because there's no water-filled hose. Cleanup is a snap and if you get the finer filter, it catches EVERYTHING. Plus it clicks on your vacuum pole like any other accessory.

Once you have it, you'll find you ALWAYS use it vacuum rather than the hose.
