Abstract
A stair vacuum device for automatically vacuuming stairs includes a pair of vacuum units coupled together by a connector. Each vacuum unit comprises a vacuum housing having a slot extending through a bottom surface of the vacuum housing. A plurality of side rollers is coupled to the vacuum housing for moving the vacuum housing in a first direction. A plurality of forward rollers is coupled to the vacuum housing for moving the vacuum housing in a second direction transverse to the first direction. A suction device is coupled to and positioned in the vacuum housing such that the suction device provides suction through the slot in the vacuum housing. The connector couples the vacuum units together in spaced relationship wherein the vacuum units move in tandem to vacuum the adjacent stair surfaces simultaneously.
