Abstract
A vacuum cleaner includes a base having first and second inlet ports and a fan configured to draw air through the inlet ports into the base. A vacuuming head is removably attachable to the base to channel air from a surface into the first inlet port to clean the surface while covering and blocking the second inlet port. An attachment, different than the head, is removably attachable to the base to channel air into the second inlet port.
