I clean pools for a living. Mostly commercial, but some home pools.

I am looking for a portable vacuuming system that can be used every day and will help speed up the cleaning process versus the conventional hook up to the pump system.

I've heard about the Power Vac systems. Has anyone used these systems or have any pros/cons with them?

Do they last a flu day? Do they clean sand and small leaves? Where can they be purchased from?

Lastly, are there other systems on the market that get a pool clean without going in/out of a pump room hooking up hoses?

Thanks so much.
