The Tornado Pond Vacuum removes dirt and debris from your pond in minutes without having to drain away the water! This clever British invention attaches to your garden hose and the water pressure creates a whirlpool in the vacuum head which sucks up dirt and debris (know as a Venturi effect). This collects in a re-usable muslin bag, allowing the clean water to pass through. The pond debris makes useful garden fertiliser! As the PondVac is water powered, you need reasonable water pressure to make the PondVac work effectively. The vacuum head must also be submerged in water to operate. The special brush attachment has special rollers which glide easily over the pond bottom, gently removing the dirt whilst protecting pond life and fish. Pondvac comes complete with a lightweight 3ft long telescopic aluminium handle.
