Abstract
A vacuum cleaner having a housing, a suction fan, a dustcup, a cover and an inlet into the dustcup. The dustcup is removably secured to the housing, and includes a cup end wall, a sidewall extending from the cup end wall, and an open end opposite the cup end wall. The cover can be connected to the open end of the dustcup, and includes an air outlet in fluid communication with the suction fan, and a filter covering the air outlet and extending from the cover towards the cup end wall. The cup end wall includes a barrier positioned to be contacted by air flowing through the dustcup to thereby separate dirt particles from the air.
