To provide an electric car-washing unit capable of easily performing efficient and quick car-washing.

The handy type car-washing device for the automobile is provided with a water suction pump and a rotation brush rotated/driven by an electric motor at a distal end of a pipe-like rod built-in with a water suction hose. Stain on a vehicle body surface is rubbed down/removed by the rotation brush while spraying water sucked by the water suction pump through the water suction hose from an injection hole provided on the rotation brush to the vehicle body surface by jetting force by a water wheel impeller. Further, when the wet vehicle body is rubbed down, the rotation brush is replaced by a rotation plate with rag and the vehicle body is rubbed down by it.
