Purchased items may be available for pick-up by a customer inside a store, available for pick-up at a drive through window, and/or delivered to the customer at a fuel dispenser. A payment mechanism may be provided in conjunction with the tablet computer. The tablet computer provided may be constructed in such a way to be protected from physical damage and weather.

Abstract: A filter assembly for a vacuum cleaner that includes a main housing having an inlet and an outlet. A motor moves air from the inlet to the outlet, and a first filter is arranged between the inlet and the outlet for filtering the air. An inner wall and an outer wall that is spaced apart from the inner wall form a cavity between the walls. The cavity is located between the first filter and the outlet. The inner wall has an inner opening that permits air to flow from the first filter into the cavity, and the outer wall has an outer opening. A back cover is removably secured to the outer wall over the outer opening to seal the cavity and guide the air from the cavity to the outlet. The back cover includes an access opening that is removably secured to the back cover over the access opening to seal the access opening. A filter cartridge is removably disposed within the cavity.
