Random motion cleaner
First Claim
1. A self-propelled bare floor cleaner, comprising:
- a dusting assembly; and
a random motion generator operatively connected to said dusting assembly, said dusting assembly comprising;
a frame having a wall, wherein said wall is cylindrical and has a first end, said first end of said cylindrical wall defining a first cylinder wall opening having a diameter larger than the diameter of the random motion generator, wherein said first cylindrical wall opening receives the random motion generator, said frame further including an angled wall section attached to the first end of the cylindrical wall and extending outwardly therefrom and a peripheral lip attached to the angled wall section;
a securing mechanism for securing the random motion generator within the frame; and
a dusting cloth attaching to the frame;
wherein said random motion generator is secured within said frame a pre-determined distance from said frame.

Abstract
A self-propelled floor cleaner is provided having a random motion generator which enhances the maneuverability of the floor cleaner. The random motion generator is rotatably attached to the frame of the cleaner and propels the cleaner across the floor in a random motion. This random motion facilitates cleaning of the floor by making the cleaner easier to manipulate. The random motion generator includes a hollow spherical shell. In the preferred embodiment, the hollow spherical shell houses a weighted motor assembly which is rotatably mounted on a center fixed axle which extends diametrically between the first and second hemispherical halves and is attached thereto. The weighted motor assembly is comprised of a motor housing and a power source, such as batteries or cells. A motor is housed within the motor housing and rotates the motor housing about the center fixed axle. The power source is mounted to one side of the motor housing to provide an unbalanced weight to the motor assembly relative to the fixed center. This unbalanced weight causes the random motion generator to roll across the floor in a random motion and, thus, the floor cleaner is also propelled across the floor in a random motion to facilitate cleaning of the floor.
