The PondoVac 4 is the ideal choice for regular cleaning as it provides non-stop pond cleaning without delays, even when the tank is emptying. It uses an innovative system of two-chambers which are filled and emptied in alternate cycles. When one chamber is full, a mechanical valve is activated by a float. This triggers emptying of the first chamber and allows the second to be filled. It comes complete with tube extensions to help you reach those difficult corners, and four suction nozzles (including a special nozzle for sucking up string algae). It has two wheels and a folding handle, making it easy to move and is also ideal for use as a wet and dry vacuum around the house.
 
We use the Oase PondoVac 4 on all our pond cleaning jobs, and we love it!
