Abstract: A wand for a domestic appliance (e.g., vacuum cleaner) includes a plurality of tubes which are dimensioned to telescope inside one another. Each tube is associated with a securing mechanism for securing the tube in an extended position with respect to another of the tubes. Adjacent securing mechanisms are positioned on their respective tubes such that, when the tubes are retracted, one securing mechanism presses against another to release the other securing mechanism. Thus, a user does not need to separately operate each securing mechanism when extending the wand. Also, the tubes automatically secure themselves in an extended position with respect to one another. A hook on the widest tube cooperates with a collar on the narrowest tube to retain the tubes in a stored position.

Abstract: A vacuum sweeper vehicle has a sweeper body including a frame. A pair of front wheels are supported by an axle apparatus at a forward end of the sweeper body. The axle apparatus is constructed to provide a space between the front wheels. A pair of rear wheels are supported at a rearward end of the sweeper body. A container is coupled to the sweeper body for receiving debris. A suction hose extends between the container and a vacuum nozzle proximal a forward end of the body. The suction hose extends through the space between the the front wheels. A suction device draws the debris from the nozzle, into the container, and a brush coupled to a forward end of the sweeper body sweeps debris from a ground surface.

Abstract: A dual filter arrangement for a vacuum cleaner for filtering particles of dust and debris from an airflow passing through the vacuum cleaner. The dual filter comprises a coarse pre-filter having an array of pores formed therein of substantially uniform diameter and a fine primary filter which is located rearwardly of the pre-filter in the direction of flow of the airflow. The dual filter is releasably latched to a main housing portion of the vacuum cleaner housing. A nose cone is removably secured to the housing and circumscribes the dual filter assembly. The dual filter enables even more efficient filtering of contaminants from dust and dirt entrained air ingested by the vacuum cleaner. Attachment of the dual filter to the main housing portion provides the additional advantage of increasing the capacity of the nose cone and eliminating the need for the user to handle the dual filter assembly when emptying contaminants collected within the nose cone.
