The aft portions of the body have a lid portion that may be opened to gain access to the interior in which there is mounted a water container vessel in which water may drip or drain from the rearwardly-pivoted sponge and for gaining access to the dust storage structure of the vacuum cleaner inner structure. Also the rear wheels of the toy truck are drivable through gear connections by the electric motor. There is provided an off-on switch for turning on and off alternately, the motor. A biasing spring holds the pivoted arms downwardly in each of alternately pivoted positions.
