发明名称 Swimming pool vacuum hose attachment for spot cleaning
摘要 A spot cleaning device for a swimming pool cleaning system having a vacuum source and a vacuum hose having an end portion forming a vacuum inlet. The spot cleaning device is arranged to be coupled to vacuum hose and to a pole. The spot cleaning device includes a releasable connector for releasably mounting it on the pole. In one embodiment the device includes a hollow body to which the vacuum hose is coupled and which includes an inlet port which communicates with the inlet port of the vacuum hose. In another embodiment the device makes use of the vacuum hose's inlet port directly. When either device is coupled to the vacuum hose and mounted on the pole the inlet port can be positioned adjacent material, e.g., leaves, mud, algae, stones, etc., desired to be removed from the pool so that when the vacuum source is operated suction at the inlet port pulls that material directly into the inlet port without creating a cloud of debris.
