Abstract
Insertion of a dust wand into a portable vacuum filtration canister removes foreign matter therefrom when and where necessary without polluting the air. A powerpack provides cordless (rechargeable or non-rechargeable) and corded operation. A readily serviceable grid filter, and a HEPA or other filter provides cleaned air free of dirt, dust and allergens.
