    Abstract: A pool cleaning apparatus weighted to rest on a pool bottom. The apparatus includes a manifold for discharging water under pressure into a plurality of sweep hoses and into a plurality of venturi jets. The sinuous action of the sweep hoses places small foreign particles in suspension, and tends to draw larger debris such as leaves toward the inner ends of the hoses. The jets discharge into a venturi chamber which is spaced above the pool bottom by support legs. This induces a flow of pool water into the venturi chamber, carrying the larger debris through the venturi chamber for collection in a removable debris or leaf bag.
