Abstract
An improved vacuum shoe for use on a self-propelled cleaning apparatus is disclosed. Specifically, the vacuum shoe may have a gliding member either integral or connected to the shoe housing. The gliding member is designed to decrease the drag coefficient of the vacuum shoe as it traverses a surface thereby increasing the machine's efficiency and decreasing the amount of required operating power.
