A floor cleaner device is described comprising a rolling support on which is mounted a tiltable handle that can be secured in various angular positions during use by means of a set of solenoid actuated locking pins which engage a set of bores defined on the handle frame. During use, the device is balanced between a first set of wheels and a rotatable cleaning element. A second set of wheels is maintained in an elevated position by the handles during use and out of contact with the floor surface which is being cleaned. To conserve space during storage and when not in immediate use, the device may be positioned in an upright position and stable manner by tilting the handle to a vertical position and engaging the actuated pins into the appropriate bores to effect upright positioning. This tilt configuration will lower the second set of wheels into contact with a floor surface, and balance the device between the two sets of wheels, and consequently the device will occupy less space.

[ I claim:] [1.] The floor cleaning device, comprising:a.) a base portion enclosing a rotatable cleaning element and drive motor components therefor;b.) a frame element attached to the base;c.) a first set of wheels mounted on the frame element and adapted for continuous contact with the floor, and which counterbalance the base portion and floor cleaning device during use;d.) a second set of wheels with extended hubs rotatably mounted on the frame element, and secured in position through sets of solenoid actuated, spring loaded, pin and bore interlocks;e.) a generally U-shaped handle frame providing fork elements, a fork element being rotatably mounted at each end of a corresponding wheel hub, and attached thereto;f.) pin locking plates mounted on each side of the handle frame and providing a series of circularly disposed bores; and,g.) pin loading plates mounted on each side of the frame element and providing spring loaded, solenoid actuated locking pins disposed adjacent to the circularly disposed bores of the pin locking plates;whereby, in the floor cleaning mode, the positioning of the locking pins with respect to the handle frame causes the first set of wheels and base portion to be in continuous contact with the floor, and the second set of wheels is maintained out of contact with the floor, and in the storage and moving mode, the locking pins are disengaged from the handle frame, the handle is rotated to elevate the base portion and components out of contact with the floor, the locking pins are re-engaged to lock the handle frame into an upright position, and the second set of wheels are lowered into contact with the floor, the first and second sets of wheels thereby counterbalancing the floor cleaning device.
