The Pondmax PV450L Pond Vacuum is the ideal tool to keep your pond clean. The PV450L is an electric pond vacuum designed to provide high suction and a large capacity waste tank.

Then it returns to suction mode and makes cleaning out the debris in the bottom of your pond or fountain a breeze. If you want to reduce the frequency of draining your pond to clean it buy a PV450L
This is the product you need if you want to keep your pond as clean as possible!
