1. A wet-dry vacuum cleaner comprising:
a collecting bin; and
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,
an exhaust outlet,
a cyclonic separator positioned within the housing, the cyclonic separator including a dirty air inlet, a chamber, and a clean air outlet,
a suction motor assembly operable to create a working airflow path from the dirty air inlet to the exhaust outlet, and
a filter disposed within a filter housing hanging downwardly from the suction motor assembly, the filter positioned within the working airflow path adjacent the clean air outlet of the cyclonic separator,
wherein the filter housing receives air from the clean air outlet of the cyclonic separator,
wherein working air in the working airflow path 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.
