ABSTRACT:
A hand-held, pocket size vacuum with scraper combination is disclosed which is primarily for use when rubbing off and cleaning up the scrapings left behind from a "scratch-off" lottery ticket. Activated by a power switch and battery, the DC Motor and centrifugal blower are located directly above a removable residue cartridge with filter. The centrifugal blower creates a flow of air between an intake port and discharge ports which flows past the storage container which collects the scrapings for subsequent disposal. The device becomes a scraping device through use of the scraper blade or abrasive wheel mechanism which is affixed to one end of the unit near the vacuum intake port.
