The Spa and Kiddie Pool Vacuum Cleaner is great for above ground pools, wading pools, spas, ponds and waterfalls. No filter system required. Includes handle, however can be attached to a larger telescopic pole for large pool leaf clean up. Simply attach included bag by securing the draw string, attach a garden hose and slowly ease the vacuum back and forth over the area requiring cleaning. The force of the water from the hose creates a venturi action under the vacuum, drawing the dirty water into the filter bag, which will retain the dirt particles. Adjust water pressure to create proper venturi.
