US Patent 7168129 Surface cleaning device

A surface cleaning device used with a vacuum cleaner nozzle inlet to clean a selected surface profile, includes a housing with a surrounding sidewall defining a housing interior. A divider is disposed within the housing interior, to separate into a first and second housing interior. The surrounding sidewall terminates in a first opening communicating between the first housing interior and an exterior environment and a second opening communicating between the second housing interior and the exterior environment. The first and second openings are approximately matched in profile to respective selected surface profiles to clean. A divider aperture collar is adjacent to the divider forming a fluid communication between the first and second housing interiors. The divider aperture collar is removably engagable to the nozzle to create a substantially fluid tight communication selectively between either the first housing interior and the nozzle or the second housing interior and the nozzle.
