AbstractA wet-dry vacuum cleaner includes a housing assembly providing a cavity, a motor within the cavity, and an impeller driven by the motor to produce a vacuum. A canister has an intake nozzle for recepton of dirt, liquid, and air drawn into the nozzle by the vacuum. The nozzle has an air intake port and a downwardly facing air exit port within the canister. A filter assembly is largely within the canister and provides an air flow path from the nozzle to the impeller. The filter assembly includes a tubular filter holder having a large diameter rear end sealingly engaging the end of the canister remote from the nozzle and a front end spaced a substantial distance forwardly from the rear end and a filter intake element within the canister and in communication with the filter holder.
