A portable hand held vacuum cleaner is disclosed as having a housing with a handle to lift and operate the vacuum cleaner, and a nozzle/debris container releasably locked to the housing. The housing contains a motor driven blower that draws air and debris (wet or dry) into the nozzle/debris container for depositing the debris therein, while allowing air to be exhausted through the blower and then through the housing to atmosphere. The blower is constructed with first and second jointly rotatable elements having a series of circumferentially spaced blower exhaust passageways and a transversely extending blower passageway adjacent the nozzle/debris container, for increased efficiency. A combined filter and seal is positioned in sealing engagement between the housing and the nozzle/debris container while affording filtering of debris from air between the nozzle/debris container and the blower in the housing. The housing is also capable of accommodating different multiple combinations of batteries with the motor and the size of the blower being increased to accommodate the increase in the number of batteries in the housing. For wet vacuuming, a squeegee with a wiper blade is available. Also, a one-piece push button facilitates operation and releasable locking/unlocking engagement of the housing relative to the nozzle/debris container.
