The present invention is a filter assembly for a vacuum cleaner. The vacuum cleaner includes a motor, a housing enclosing the motor, and a fan driven by the motor for producing a vacuum. A canister is removably attached to the front end of the housing and has an intake nozzle for the reception of foreign matter, liquid and air drawn into the canister in response to the vacuum developed by the fan. The assembly includes a filter for filtering foreign matter from the air entering the canister. The asssembly also includes a filter housing for housing the filter. The canister includes an area of thinner material with a smoother texture than the rest of the canister to provide a generally transparent window for visually determining the amount of foreign matter within the canister.
