Simply assemble the vacuum cleaner together and connect it to your garden hose. The water pressure from your garden hose creates a venturi action which sucks up debris and leaves into the vacuum’s collection bag. NO PUMP-FILTER circulation system and NO ELECTRIC POWER required. It is PORTABLE and HANDY to use. Ideal for above ground and inflatable pool, spa, waterfall, fountain, and pond. It is also perfect for vacuuming inground spa and small pool. ***Watch this video link for assembly and operation (https://www.youtube.com/watch?v=h-kDzRiNZaM)***.
