Abstract: A disinfecting device is presented having a UV light source for radiation of a cleaning medium to eradicate the medium of infestation agents such as molds, viuses, bacteria and dust mites. The device enhances the disinfection of the medium by providing mechanisms for enhanced penetration of the UV light into the cleaning medium. The device also offers enhanced heat dissipation to promote effective use of the device. Also provided are safety mechanisms to promote the safe and advantageous use of the UV device.

Abstract: An orbiter floor machine for treating floors, the floor machine having a top-hat-like housing with a handle extending upwardly toward a user. The floor machine includes a motor having a rotatable drive shaft extending therefrom, the drive shaft having a shaft axis. An annular flywheel has an axial opening that fixedly receives the drive shaft so that rotation of the drive shaft causes rotation of the flywheel. A bearing assembly has an eccentric aperture through which the drive shaft extends such that the bearing assembly has an axis that is radially spaced from the shaft axis. The bearing assembly is secured to the flywheel such that the rotation of the flywheel causing the bearing assembly to orbitally rotate such that the bearing axis orbits about the drive shaft axis. A counterbalance weight is secured to an outside perimeter of the flywheel in a position opposite to the bearing assembly axis with respect to the shaft axis.

Abstract: A brush assembly is fixedly mounted to each side wall of a vacuum cleaner head closely adjacent the axis of a rotary brush. The brush bristles of each assembly are directed so as to brushingly engage the wall-floor corner. The brushes are aligned in the direction of longitudinal movement of the vacuum cleaner. A guide slot is formed in the head adjacent the end of each brush assembly, with each slot providing communication between the outside of the head and the vacuum chamber containing the rotary brush. Dirt and debris loosened by the brush assemblies is sucked through the channels formed by the slots and the floor, and then into the path of the rotary brush and into the vacuum chamber.
