    Abstract: The present invention is an apparatus comprising a cylindrical container having a lid with two openings, a first opening and a second opening. An elbow shaped pipe is attached at each opening, respectively, and fastened by metal clamps. The posterior end of the first pipe extends down 1.0 inches into the cylindrical container. The posterior end of the second pipe extends down 0.5 inches into the cylindrical container and is attached to a filter. The anterior end of the second pipe extends up from the second opening and is connected to a vacuum. When the vacuum is on, the suction mechanism and air flow inside the cylindrical container forces dust and fine particles through the filter and up through the second pipe into vacuum. The dirt and fine particles are collected into the vacuum bag or receptacle located inside the vacuum, while the small items remain inside the cylindrical container.
