Abstract
A dual filter wet/dry hand-held vacuum cleaner includes a two-stage filtration system effective to provide liquid and/or dry pick-up while minimizing the frequency with which it needs cleaned out that, at cleanup time, may be cleaned efficiently with little or no dust generation and minimal or no direct contact with accumulated grime.
