Abstract: A disinfectant sprayer assembly, including a tank defining a volume, a disinfectant suspension contained within the volume, a nozzle having a size variable spray opening, a pump operationally connected to the volume and to the nozzle for pumping disinfectant from the volume through the spray opening to apply disinfecting to a predetermine surface having a predetermined set of physical characteristics for a period of time, an ion generator operationally connected to the volume for ionizing the disinfectant suspension, and a microprocessor operationally connected to the size variable spray opening. The ion generator voltage, spray opening size, and distance between the predetermined surface and the spray opening are predetermined based on the predetermined set of physical characteristics of the surface.

Abstract: An air processing system is disclosed. The system includes a mobile robot, and the robot includes an intake module, the module includes a manifold, a first airfoil disposed on the manifold and configured to allow air of an area designed to have its air cleaned to enter the manifold, a second airfoil disposed one the manifold opposite the first airfoil configured to allow air from the area to enter the manifold, and a collector provided in between the first airfoil and the second airfoil and disposed on the manifold configured to receive air from the manifold and thus filter the air, and the system further includes a controller configured to provide one of remote control and autonomous control of the mobile robot.
