A portable vacuum cleaner for use in both dry and wet operations includes a main body case housing a fan motor and having intake and discharge openings, a dust case having a suction part and removably attached to the main body case around the intake opening, a filter housing removably installed in the dust case and having a filter accommodated therein to cover the intake opening with the filter, and a seal member peripherally interposed between the dust case and the main body case and/or filter housing. The filter housing has on the suction side of the constitutional wall thereof an annular wall which projects in an annular form toward the suction part and forms a well for water drawn in from the suction part, and also has a through hole positioned above the annular wall which permits the passage of air drawn in from the suction part.

A portable vacuum cleaner operable for use in concurrent dry and wet operations, comprising: a main body case having intake and discharge openings; a fan housed in the main body case between the intake and discharge openings; a dust case having a suction nozzle adapted to draw in water, air and debris during operation of said vacuum cleaner, said dust case having a top and being removably secured to the main body case adjacent the intake opening so as to completely cover the intake opening; a filter housing having a through hole, said filter housing being removably installed in the dust case adjacent the intake opening and having an intake side distal from the intake opening, and said through hole being provided for the passage of air and debris drawn in through the suction nozzle during operation of the vacuum cleaner; a filter disposed in the filter housing so as to cover the intake opening; a seal member peripherally interposed between the filter housing and the dust case; and an annular projecting wall mounted in the dust case adjacent the intake side of the filter housing and having an open end in opposed relation to the suction nozzle to form a well for storing, during periods of nonuse with said vacuum cleaner oriented so as to upwardly point said suction nozzle, water drawn in through the suction nozzle during operation of the vacuum cleaner; said through hole in the filter housing being defined between the annular projecting wall and the top of the dust case, the position of the through hole being effective for minimizing passage through said through hole of liquid drawn in through the suction nozzle during operation of the vacuum cleaner.
