ABSTRACT:
A removable cover for my earlier patented magnetic cleaning devices, the cover comprising a plurality of hollow pockets interconnected at their rear, open ends by thin webs which permit longitudinal flexiblity. The interconnected pockets are configured and positioned to receive the projecting magnet pockets of a magnetic cleaning device attached to a vacuum cleaner or a sweeper in a snug, friction fit engagement, thereby securing the cover releasably onto the magnetic cleaning device. When the magnetic cleaning device passes over a floor surface and picks up magnetically attracted objects, the magnetic attraction holds the magnetically attracted objects firmly against the overlying cover. The cover is then simply pulled off of the magnetic cleaning device and the metallic objects, now released from the magnetic attraction of the cleaning device, simply fall away from the cover into a waste receptacle, or alternatively as in this embodiment, into the confines of a forwardly projecting tray provided about the periphery of the cover adjacent its rear, open end. The cover is then ready to be reinstalled onto the magnetic cleaning device for another use.
