A robot cleaner comprising: a cleaner body including a wheel unit and a controller controlling driving of the wheel unit a suction unit disposed in the cleaner body, the suction unit sucking air containing dust and a sensing unit disposed at the front of the cleaner body in which the suction unit is disposed, wherein the sensing unit includes a first sensing part disposed respectively inclined with respect to side and top surfaces at an upper corner portion of the cleaner body to simultaneously photograph front and upper parts of the cleaner body.

A robot cleaner comprising: a cleaner body including a dust container accommodation part formed to be recessed toward the front from the rear thereof; a suction unit mounted in the cleaner body to suck air containing dust; a dust container accommodated in the dust container accommodation part, the dust container collecting dust filtered from sucked air; and an exhaust port formed at an end portion of one rear side of the cleaner body, which surrounds the dust container accommodation part, to discharge filtered air to the outside, the exhaust port disposed along the height direction of the cleaner body.

A autonomous cleaner includes: a cleaner body including a wheel unit for autonomous traveling; a suction unit provided to protrude from one side of the cleaner body, the suction unit sucking air containing dust; a sensing unit provided at the one side of the cleaner body; a dust container accommodated in a dust container accommodation part formed at the other side of the cleaner body, the dust container collecting dust filtered from sucked air; and a dust container cover hinge-coupled to the cleaner body to be rotatable, the dust container cover being provided to cover a top surface of the dust container when the dust container cover is coupled to the dust container.

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. A pair of seals within the inlet valve retains a nozzle handle mounted on the end of the hose in a stored position when the hose is in a retracted position and provides an air seal between the handle and vacuum supply conduit. A locking mechanism mounted on one embodiment of the inlet valves automatically locks the hose in a selected extended position when manually pulled from the inlet valve by a locking finger engaging an adjacent section of the hose. An electric switch on the inlet valve enables a user to actuate the vacuum supply source. A mounting bracket enables the inlet valve to be mounted at various locations in the structure and a pair of seals enables the inlet valve to be open to the ambient atmosphere.

A clutch device for an upright vacuum cleaner and an upright vacuum cleaner having the same are provided. The clutch device is disposed between an electric motor assembly and a machine body assembly of the upright vacuum cleaner, the electric motor assembly includes an electric motor housing and an electric motor, the machine body assembly includes a machine body and a bridging member rotatably connected to the electric motor housing. The clutch device includes a slide chute; and a triggering member having a first end provided with a sliding column slidaby fitted in the slide chute and a second end provided with a toggling rod configured to stir the electric motor to move. When the bridging member drives the slide chute to move, the sliding column slides along the slide chute to rotate the triggering member. When the triggering member rotates, the toggling rod stirs the electric motor to rotate.

Embodiments of the present invention provide systems and methods for disinfection of aircraft galleys and lavatories and other surfaces. The embodiments may use UV light sources and/or a disinfection unit powered by a fuel cell or other external power source.

A vacuum system for vacuuming is disclosed. The vacuum system includes a baseboard cleaning attachment, a floor cleaning attachment, and a hose attachment. Each of the attachments is selectively mounted to a hose of the vacuum system for vacuuming floors, baseboards and tight spaces. The baseboard cleaning attachment includes a brush head having a right-angled portion, and a curved portion. The brush head includes a neck to mount the brush head to the hose. The right-angled portion is aligned with the baseboard and is used to vacuum. The floor cleaning attachment includes an elongated tube, and an under furniture handle mounted to the elongated tube. The elongated tube includes a beater head with a beater. The elongated tube is mounted to the hose, and the under furniture handle is used vacuum under furniture. The hose attachment is in an S-shape for tight spaces.

A suction head for a vacuum cleaner comprising a base plate with a base plate channel open towards a surface to be vacuumed and a suction channel in fluid communication with the base plate channel is described. Said suction channel comprises an inner tube and an outer tube, wherein the inner tube is fixed to the base plate channel and the outer tube is rotatable telescopically with respect to the inner tube.
