The Oase Pondovac 3 Pond Vacuum is a two-chambered pond vacuum that removes capacity restrictions and allows the pond to be vacuumed constantly. Two identically sized cylinders are filled and emptied in alternating cycles. When one container is full a valve is mechanically activated by a float, triggering the alternate container to empty while at the same time allowing the other cylinder to be filled.
The Pondovac 3 is easily moved (built in wheels) and includes a string algae nozzle, wide nozzle with rubber lip, a crevice tool, a floor nozzle, vacuum tube extension and a debris collection bag. It is also great for cleaning out Waterfall Filters without a back flush.
