A device for vacuuming, which is powered by the leg exercise motion of a user, includes a pair of bellows units which are mounted on the user's feet and a tank which is mounted on the user's back. A hand-held cleaning wand is connected to the tank by a flexible hose. The user alternately compresses and releases the bellows units, overcoming an internally mounted spring, and as the bellows unit returns to its original shape, a partial vacuum is formed therein. The bellows units are connected to the tank by flexible tubes and the partial vacuum draws air into the cleaning wand, thereby vacuuming dirt and debris into the tank.
