An electric vehicle with a cleaning device includes an electric motor, a cleaning device connected with a pipe installed in a vehicle cabin, a first clutch that connects and disconnects the electric motor with an axle of wheels of the vehicle, a second clutch that connects and disconnects the electric motor with the cleaning device, a control unit that controls one of the first clutch and the second clutch to selectively connect one of the cleaning device and the axle with the electric motor and activate the cleaning device.

A central vacuum cleaning system includes an inlet valve mounted at various locations in a structure or RV and connected to the inlet end of a vacuum conduit. A section of hose is slidably mounted within the conduit and extends from the inlet valve for cleaning an adjacent area. The hose includes a hose plug connected with a distal end of the hose. The hose plug includes an annular channel and an orthogonally aligned slot. The hose plug may also include a first seal and a second seal.

Vacuum cleaners to be mounted in a vehicle are disclosed. Some of the vacuum cleaners have a modular design that allows the vacuum cleaners to be arranged, assembled, and/or installed in different configurations and to fit in different spaces within the vehicle. Vacuum cleaners may include a vacuum module, a collector module, and/or a hose storage module. An interconnecting duct is configured to operatively couple the vacuum module and the collector module in any one of a plurality of different predefined assembly configurations. The collector module may have a debris canister that may be lifted straight out of a collector housing. The vacuum cleaner may be installed in a vehicle in a manner to allow easy removal of the debris canister without disconnecting and/or removing other portions of the vacuum cleaner.

An ultraviolet C (UV-C) illumination system includes a central disinfection unit (CDU), a heating, ventilation and air conditioning (HVAC) illuminator unit (HIU), and a beam scanning device. The CDU includes a fiber-coupled UV-C unit (FCU) configured to provide a UV-C light, a microcontroller, and a smart control unit (SCU) that controls each of the one or more FCUs by adjusting UV-C illumination by each of the one or more FCUs. The SMU communicates to the microcontroller to adjust energy consumption based on environmental data. The HIU includes fused silica rod to uniformly scatter the UV-C light to disinfect a surrounding area, with a light intensity controlled by the SCU of the CDU. The beam scanning device is coupled to the one or more FCUs. The beam scanning device includes a fiber and a lens disposed at a fiber tip of the fiber and configured to collimate the UV-C light.

Vacuum cleaners to be mounted in a vehicle are disclosed. Some vacuum cleaners include a collector module configured to collect debris and a motor/impeller unit connected to the collector module. The collector module includes an air inlet and an air exhaust opening, and the motor/impeller unit is configured to draw air through the collector module from the air inlet to the exhaust opening. A hose storage module is connected to the air inlet, and a vacuum hose is stored inside the hose storage module.
