Vacuum Suggestions for AGP

Any suggestions on a vacuum that is not automatic for an above ground pool? I have 27' and current vacuum head is a cheap $20.

Thanks,
Michele

I'm assuming you already have a pole, and vac hose?

The Rainbow ProVac is what I've used for years. We have a big one at the country club pool we service. They are very fast and effective, with adequate suction, but are expensive and some folk take a little while to learn to 'steer' them:

However, many people prefer a combo brush & vacuum like this:
