  • Patent number: 10835092
    Abstract: A vacuum cleaner attachment is disclosed having a concave vacuum head with a swivel joint that permits swiveling of the vacuum head only within the plane of the vacuum head. The concave vacuum head can have a curvature that is similar to the curvature of a cylindrical surface to be vacuumed. Thus, while a user manipulates the conduit providing the air suction to the vacuum head, the concave surface can be supported and swiveled around the circumference of the cylindrical surface to be vacuumed, while the vacuum head is also moved along the length of the cylindrical surface. Throughout this movement of the concave vacuum head, the concave opening of the concave vacuum head can stay in closer proximity and conformity to the cylindrical surface than is possible using a fixed vacuum head with a flat opening, thereby making cleaning of the cylindrical surface more effective and efficient.
