Claim 8:
9. A wet-dry vacuum cleaner comprising:
a collecting bin;
a power head removably coupled to the collecting bin, the power head including:
a housing configured to support the power head on the collecting bin,
a dirty air inlet,
an exhaust outlet, and
a suction motor assembly operable to draw working air from the dirty air inlet and expel air through exhaust outlet;

a cyclonic separator integrated within the housing, the cyclonic separator including
a plate configured to separate heavier debris from the working air, the plate having an opening defined between the plate and the housing of the power head, the opening allowing heavier debris to fall into the collecting bin, and
a clean air outlet positioned within the housing of the power head, the clean air outlet configured to receive working air unladen of heavier debris;

a filter housing hanging downwardly from the power head, the filter housing receiving air from the clean air outlet of the cyclonic separator;
a filter supported within the filter housing, the filter being disposed fluidly downstream of the cyclonic separator; and
a conduit extending from the filter toward the exhaust outlet, the conduit positioned physically in the cyclonic separator but fluidly disposed downstream of the cyclonic separator, the conduit physically separating working air entering into the filter housing though the clean air outlet and working air exiting the filter housing through the conduit,
wherein working air passes over the cyclonic separator before entering the filter housing, and
wherein working air is drawn from the clean air outlet of the cyclonic separator downwardly into the filter housing.
