  • Electric vacuum cleaner having steam discharge and cloth wiper
    Patent number: 5502872
    Abstract: An electric vacuum cleaner delivers clean water from a water supply tank to a steam generator and atomizes the water with air received from a suction generator. The steam generator converts the atomized water into steam, and the steam is discharged onto the floor through a suction head. The suction head carries a movable cloth for wiping the floor. Dirt, steam and air are sucked up through the suction head and delivered to a dirt collector where the dirt, air, and water (condensed steam) are separated from one another.
