A sanitizing vacuuming device for sanitary collection of debris includes a vacuum cleaner that comprises a power module, a suction head, and a receptacle. The suction head is operationally coupled to the power module. An intake port is positioned in the suction head. The vacuum cleaner is configured to vacuum particles from a surface through the intake port and into the receptacle. A plurality of first bulbs is coupled to the suction head proximate to a perimeter of the intake port. The plurality of first bulbs is selectively operationally couplable to the power module, positioning the plurality of first bulbs to emit ultraviolet germicidal radiation. The plurality of first bulbs is configured to disinfect the surface and to irradiate the particles that enter the intake port.

To provide an electric vacuum cleaning apparatus that can disinfect the surface to be cleaned by atomizing electrolyzed water containing hypochlorous acid and spraying or spreading the atomized electrolyzed water to this surface while moving on this surface. The electric vacuum cleaning apparatus includes: an electric blower that generates suction vacuum pressure; a suction air passage equipped with a suction port and fluidly connected to a suction side of the electric blower; an electrolyzed-water generator that electrolyzes water to produce electrolyzed water containing hypochlorous acid; and an atomizer that atomizes the electrolyzed water produced by the electrolyzed-water generator and supplies the atomized electrolyzed water to a surface to be cleaned.

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.

An autonomous cleaning robot includes a main body including a main mounting frame and an outer shell, a drive wheel assembly, a collision mitigation mechanism, a sweeping and vacuum assembly, a cleaning fluid applicator and cleaning roller assembly, a germicidal ultraviolet light disinfection mechanism, the germicidal ultraviolet light disinfection mechanism capable of disinfecting both cleaning fluid and a cleaning surface, and a main controller unit. The robot uses germicidal ultraviolet radiation to both disinfect a cleaning surface as well as to disinfect used and/or recycled cleaning fluid. A method for cleaning a floor involves activating the robot; checking fluid levels; acquiring imagery of the space to be cleaned, dispensing cleaning fluid, recycling recovered and excess cleaning fluid, irradiating used cleaning fluid, irradiating a cleaning surface, moving across a cleaning area, recording a travel path, traveling across areas not previously traveled across, and powering down when finished.

Embodiments of a unified airflow system for ultraviolet disinfection devices are disclosed. One embodiment of the present disclosure includes a unified airflow assembly and a control unit. The unified airflow assembly provides a shared airflow passage between a UV source and an airflow accessory capable of extracting contaminants from a target surface using a suction airstream. The UV source may be fluidically disconnected from the airflow accessory. The unified airflow assembly may include at least one air restriction unit in the shared airflow passage for manipulating a suction airstream therein. The control unit may be configured to drive the at least one air restriction unit to restrict the suction airstream to only one of the UV source and the airflow accessory.

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.

A municipal garden sweeper includes a mobile frame, a control box arranged on an upper portion of the mobile frame, a first exhaust pipe, and a second exhaust pipe arranged on left and right sides of the control box. The first exhaust pipe and the second exhaust pipe are configured to suck up and collect external garbage. A first exhaust fan is arranged on a connecting portion of the first exhaust pipe and the control box. A second exhaust fan is arranged on a connecting portion of the second exhaust pipe and the control box. The first exhaust fan and the second exhaust fan are configured to respectively provide power for the first exhaust pipe and the second exhaust pipe to suck up the external garbage.

This application provides a robot base station, robot system, pedestal module, and functional components of the base station. The robot base station includes: a pedestal for docking the robot and multiple functional components, each with at least one functional module, providing various services to the robot. Any of these functional components can be combined with the pedestal, and at least some of the functional components can be assembled together and then combined with the pedestal, forming a base station with various functional combinations and quantities. The robot base station is designed modularly. By combining various functional components with the pedestal according to the actual needs of users, a base station that meets diverse needs of different users can be obtained.
