Abstract
A vacuum cleaner comprising a tank for collecting material having a base, an outside surface and an opening disposed at the base. A drain system is disposed adjacent the opening and includes a drain tube having an outlet and a cap mounted to the drain tube and removably secured to prevent material from exiting the drain system. When the cap is removed, the drain tube slides out of the opening in a first direction and the outlet permits material to leave the drain tube in a direction other than the first direction.
