An extraction cleaning machine includes a housing with a fluid delivery system that includes a fluid distributor for delivering a cleaning fluid to the surface to be cleaned. A fluid extraction system includes a suction nozzle for recovering soiled cleaning fluid from the surface. A steam delivery system is operably coupled to the housing and supplies steam or heated liquid to the surface. A controller is operably coupled to the steam delivery system and at least one ultraviolet light emitting element to selectively control the steam delivery system in accordance with a first timed duty cycle to generate at least one of the steam and the heated liquid that is supplied to the surface and the at least one ultraviolet light emitting element to emit ultraviolet light to the surface in accordance with a second timed duty cycle.

A sterilizer for an autonomous robotic cleaner is revealed. An ultraviolet (UV) sterilizer is disposed on a top surface of an autonomous robotic cleaner. When the autonomous robotic cleaner is moved for cleaning the floor, consumers can activate the UV sterilizer by remote control to perform sterilization of indoor environments according to their needs. Thus a clean and hygienic environment is achieved. A person or pet in area to be cleaned is detected in a real time manner by a thermal sensor module so that the UV sterilizer is turned off immediately to protect the person or pet from injuries caused by exposure to UV light.

Apparatuses are disclosed which include one or more lamps configured to emit germicidal light, wherein the apparatuses are configured such that germicidal light emitted from the one or more lamps is projected exterior to the apparatus. The apparatuses further include wheels arranged along a bottom of the apparatus and a motor to provide automated mobility of the apparatus across at least a part of a room or area in which the apparatus is arranged. Moreover, the apparatuses include a processor and a storage medium having program instructions which are executable by the processor for activating the motor such that the apparatus is moved within the room or area while the one or more lamps are emitting germicidal light.

A method, and a floor care device (100, 200) are provided for allowing decontaminating parts of a floor care device. The floor care device comprises at least one part (110, 210) that is susceptible to contamination when the floor care device is used in a floor care mode. The method may comprise detecting a transition of the floor care device to a park mode, and in response thereto, executing a decontamination program, the decontamination program including emitting light with a wavelength of 222 nm and thereby illuminating the at least one part for the decontamination thereof.

The present invention relates to a gas driven automatic moving steam circulation window wiping robot, comprises a housing, a driving mechanism, a wiping mechanism and a steam circulation mechanism. The driving mechanism comprises a main drive shaft, a follower shaft, a first motor, a rolling wheel, a suction cup walking device. The suction cup moving device comprises a crankshaft, a support pole, suction cups and a second motor. The wiping mechanism comprises a striped wiping cloth, a UV sterilization lamp and rotary brushes. The follower shaft is drivably connected to the rotary brush. The steam circulation mechanism comprises a negative pressure suction mouth, a negative pressure pump, a water precipitation tank, a filter tank and a steam generator connected in series through pipes. The structure is reasonable, having the advantages of simple, convenient to use, saves water, safe and reliable, and having a high level of automation, can effectively solve the problem of existing window wiping robots unable to clean the corners of windows.

A portable handheld submersible ultrasonic cleaning device has a generally elongate body defining proximal and distal ends, a power supply and an ultrasonic transducer powered thereby, wherein the distal end exposes the ultrasonic transducer to agitate surrounding water when the base is submerged in the water use. A propeller device comprising a propeller may force the water across the ultrasonic transducer. When cleaning, the device may be held with the distal end thereof submerged for enhanced cleaning and removing surface contaminants such as dust, dirt, oil, pigments, bacteria and the like. The device may be stood upright upon the base on the floor of a container for hands-free application of ultrasound whilst cleaning.

A cleaning device may include a solution tank configured to store cleaning solution. The device delivers the cleaning solution from a pump discharge of the cleaning device to a flow meter. The device initiates a priming mode by opening a first valve associated with a bypass line of the device, closing a second valve associated with a cleaning head of the cleaning device, and delivering the cleaning solution from a discharge of the flow meter to the inlet of the solution tank through the bypass line. When the device is primed, it initiates cleaning by closing the first valve associated with the bypass line, opening the second valve associated with the cleaning head, and delivering the cleaning solution to the cleaning head.

An apparatus for destroying pathogens includes a platform and an LED matrix panel. The platform has a portion configured to permit passage of ultraviolet light therethrough. The LED matrix panel is disposed below the portion of the platform and includes a grid and a plurality of discreetly-controlled, ultraviolet light LEDs (UV LEDs). The grid defines a plurality of cells. Each UV LED is associated with one cell such that the cells direct the ultraviolet light emitted by the UV LEDs upwardly through the portion of the platform to sanitize an object supported on the portion of the platform.

A washing apparatus washes a cleaner having a mop unit formed at a lower portion thereof. The washing apparatus includes a tray configured to form a space to receive the cleaner and washing water. A washing unit is disposed at a lower portion of the inside of the tray in contact with the mop unit. The washing unit includes a first spinning mop protrusion line configured to protrude upwardly, an upper end of the first spinning mop protrusion line being inclined downwardly in a first direction.

A compact, portable, low cost ultraviolet (UV) light source apparatus irradiates select or target surfacing for disinfecting or sanitizing the target surfacing or for decomposing ozone within a defined ozone environment. The ultraviolet light source apparatus according to the present invention essentially includes a power source; an ultraviolet (UV) light source in communication with the power source, and a mechanism for powering on and powering off the ultraviolet (UV) light source. The ultraviolet (UV) light source directs ultraviolet light toward a select surface for irradiating the surface or decomposing ozone. The ultraviolet (UV) light source apparatus may be attached to any number of select surfaces or objects or may be utilized to receive and hold objects for treating surfacing thereof.
