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 device includes a releasable connector for releasably mounting it on the pole and has a hollow body to which the vacuum hose is coupled and an inlet port which communicates with the inlet port of the vacuum hose. A vacuum relief port is provided in the hollow body adjacent the inlet port. The device is arranged to be positioned adjacent material, e.g., leaves, mud, algae, stones, etc., 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, and with the vacuum relief port preventing the device from becoming hung up or stuck to a surface of the pool.
