High Performance! Keeping the pond floor clean and free of unsightly floor sediment, sludge, and plant remains is necessary, and unfortunately it is often quite tiresome. This is no longer the case with the Pond-O-Vac 3. Two-Chamber System which involves two identically sized cylinders that are filled and emptied in alternating cycles. If one container is full, a valve is mechanically activated by a float. This triggers emptying of one chamber while the other is being filled. Both vacuuming and emptying of the container can occur at the same time. Built in wheels for easy movement Ideally suited for wet vacuum application Large diameter casters High motor performance for better suction In Stock-Ships Fast
