Canister Vacuum Cleaner filter Technology Transfer to Larger Pre-Separator Container Innovation

摘要

#$%^&*AU2017101625A420180308.pdf#####Examiner Abstract The innovation resides in fitting a filter and/or pre-separator element(s) of a small canister vacuum cleaner onto a larger capacity vacuum, suitable for use in industrial applications. This will improve dust retention and separation of dust particles from a vacuum cleaner, vacuum suction, and work speeds, and extends operational life of vacuum cleaners
