The present invention is directed to a compact robotic device for spraying a biocide powder or liquid to a predetermined area for controlling the infestation by cockroaches and fleas. The compact robotic device comprises a robotic body that can autonomously travel to spray the powder or liquid. The compact robotic device comprises a cartridge containing the biocide powder, a spray head in fluid communication with the cartridge and configured to spray the powder or liquid over a surface and a pump coupled to the cartridge for affecting the flow of powder or liquid from the cartridge to the spray head.

A vacuum cleaner includes a body having a space that allows air to flow therethrough. The vacuum cleaner also includes a suction inlet configured to introduce the air into the body. Further, the vacuum cleaner includes a suction motor provided in the body. The vacuum cleaner includes a dust separation module provided in the body. The dust separation module is arranged between the suction inlet and the suction motor. The dust separation module separates foreign substances from the air. The vacuum cleaner includes an exhaust module that discharges the air passing through the suction motor from the body. The exhaust module includes an exhaust filter comprising a photocatalyst. Further, the vacuum cleaner includes a lighting module that radiates light toward the exhaust filter. The vacuum cleaner includes a battery supplying electrical energy for the operation of the vacuum cleaner and a controller configured that controls operations of the vacuum cleaner.

An automatic cleaning apparatus is configured to clean a floor and emit ultraviolet light for sterilizing the floor in a cleaning mode. Upon detecting that a wall is nearby, the automatic cleaning apparatus emits ultraviolet light toward a corner formed by the floor and the wall for sterilization.

An ultraviolet (UV) sterilization lighting system includes a plurality of arrays of UV sterilization lighting and a power source. The arrays of UV sterilization lighting are configured in a modular arrangement in electrical communication with the power source and enable plug-in type completion of electrical communication within the arrays. The arrays are configured in a pattern to effect desired sterilization via the UV sterilization lighting. The array formations include straight and/or curved lines, circles, triangles, squares, rectangles, pentagons, hexagons and other similar polygonal or other geometrical arrangements, whether in an ordered or disordered pattern, that are deemed most suitable to affect the desired sterilization.

Methods and systems for mobile automation control of disease spread are disclosed. A computer-implemented method includes: determining, by a computing device, a health status of a person; determining, by the computing device, that the person is sick based on the health status; determining, by the computing device, facial and body movements of the person determined to be sick; determining, by the computing device, that the person determined to be sick performed a germ-transmitting activity based on the facial and body movements; and deploying, by the computing device, a cleaning robot to clean based on the determining that the person determined to be sick performed the germ-transmitting activity.

The invention is related to a mobile industrial autonomous device that can be used to perform different functions with the modules (8) of different features which can be easily changed by the user on the same platform. Although the main function targeted with the invention is the cleaning of indoor spaces, functions such as polishing, mowing, fertilizing, spraying etc. can also be provided by the robotic platform of the invention with modules that can be easily changed by the user. It will move automatically by the help of the lidar unit (4) and the camera units on the autonomous device, scan and map the environment and determine a route for itself accordingly and perform its function.

A vacuum cleaner includes a housing that houses a suction nozzle and a fan and is configured to be moved on a surface to be cleaned, a cartridge including a solution, a spray nozzle that directs a spray on the surface, a valve that actuates the spray nozzle and a controller that selectively operates the valve based on pre-programmed instructions. The spray nozzle is positioned on the housing in a direction away from a direction of movement of the housing.

A sterilization apparatus includes a light source unit for emitting light to a sterilization region for sterilizing a target particle, a power supply unit for supplying power to the light source unit, and a photodiode unit for sensing the light from the light source unit. The photodiode unit is driven by the light from the light source unit.

A surface cleaning device includes a nozzle and an odor dial assembly. The nozzle includes a nozzle housing and a dirty air passageway. The odor dial assembly include a fragrance member and a dial body configured to be removably coupled to the nozzle housing. The dial body at least partially defines a fragrance cavity configured to at least partially receive the fragrance member and a fragrance passageway extending therethrough. The odor dial assembly is configured to transition between a plurality of user-selectable positions to adjust an amount of fragrance particles released by the fragrance member into the dirty air passageway.

The present disclosure provides a self-propelled pathogen detection device in which a place where a pathogen is highly likely to be present in a space such as an inside of a facility is allowed to be configured preferentially to be a target region of detection. The self-propelled pathogen detection device according to the present disclosure comprises a housing; a detection part for detecting a pathogen; a movement mechanism for moving the housing; a position acquirement part for acquiring position information representing a current position of the housing in a space; and a control part which determines a target region in the space on the basis of traffic line information on a person in the space, and controls the movement mechanism to move the housing in the target region on the basis of the position information. The detection part detects the pathogen in the target region.
