Abstract: A vacuum cleaner that includes a suction motor and a filter assembly. The filter assembly surrounds at least part of the suction motor and has a frame to which a filter medium is attached. The filter medium is spaced from a wall of the frame such that an arcuate passageway is defined between the filter medium and the frame. A part of the air expelled by the suction motor enters a first end of the passageway and moves around the passageway in a clockwise direction. A further part of the air expelled by the suction motor enters a second end of the passageway and moves around the passageway in a counter-clockwise direction. Air within the passageway then passes through the filter medium.

Abstract: A system for and method of processing customer orders are disclosed. The system contains an order entry device, software having a database and at least an interface function, an algorithm adapted for selecting the order processing location and adapted for transmitting customer orders to the order processing device. The method of processing customer orders includes collecting the orders at an order entry device such as a point of sale, prioritizing and queuing the orders, identifying the best point of delivery for each order, transmitting the order to the point of delivery and processing the order at the point of delivery. This saves time for the customer and improves the accuracy of filling the orders.
