A stick pump assembly includes a tube having a first end, a second end, and an axis extending through the first and second ends. The tube accommodates fluid to flow therethrough. The stick pump assembly also includes a pump including a motor and an impeller. The pump has an inlet adjacent the first end and in fluid communication with the tube. The stick pump assembly further includes a handle having an outlet adjacent the second end and in fluid communication with the tube. The handle includes a receptacle configured to receive a battery pack. The stick pump assembly also includes a filter assembly supported by the pump and in fluid communication with the inlet. Fluid flows into the stick pump assembly though the inlet, around the motor, through the tube, and out of the stick pump assembly through the outlet.
