 Pond Vacuum Cleaners are a great way to keep your pond clean without having to spend a weekend kneel deep in gunk. Pond vacuums work by drawing in the water into a collection container and returning the the filtered water back to the pond. They will need an extension cable which you will need a mains socket available to plug into.
They come with an extra long hose so that you can easily get around the pond without having to move the base unit too much around the pond. Without doubt this is the only way to clean a pond. |
