You’ll never need to drain your pond again. Working like a vacuum cleaner this clever British invention uses the Venturi system to suck dirt, dead leaves and debris from the floor of your pond. By attaching to your garden hose and the water pressure creates a vacuum effect which sucks up any dirt and debris from the pond floor, straight into the re-useable muslin bag. Suction is controlled by your water pressure. The filtered clear water then passes back into your pond. The special triple brush rollers glide easy over the pond floor, gently removing dirt whilst protecting pond-life and fish. With a lightweight extending handle, it’s suitable for ponds up to 4 feet deep or other water features and shallow pools. Harmless to fish and other pond life.
