A cleaning device for removing hair and/or debris from a rotary brush and a method using the same are disclosed herein. The cleaning device includes an elongated rod having a first end, a second end, and a rod axis, the first end of the elongated rod being oppositely disposed relative to the second end of the elongated rod, the elongated rod further including a plurality of protruding elements projecting outwardly from the elongated rod, the plurality of protruding elements being disposed at least partially around a periphery of the elongated rod and along at least a portion of a length of the elongated rod between the first end and the second end. The first end of the elongated rod is configured to be coupled to a rotary motion input device that is sufficient to rotate the plurality of protruding elements of the elongated rod about the rod axis.

A cleaning apparatus that cleans a detection surface of a detection element includes a first cleaning member, a second cleaning member, a driving device, to which the first cleaning member and the second cleaning member are attached, configured to drive the first and second cleaning members to approach and recede from the detection surface, and a control unit configured to control the first and second cleaning members and the driving device.

A substrate cleaning apparatus configured to clean a surface of a substrate having a circular shape by bringing a cleaning member into contact with the surface of the substrate and rotating the substrate and the cleaning member relatively is provided. A contact region of the cleaning member which comes into contact with the surface of the substrate is widened in a radial shape from a center side of the substrate toward a peripheral side thereof.

A kitchen hood has a first housing and a second housing that slides into and out of the first housing to adjust a length of the kitchen hood. The first housing has a fan to suction air, an outlet, and an air quality sensor assembly to continuously detect air quality in a kitchen. The second housing has an inlet and suction grill through which air is suctioned, a steam cleaning assembly to automatically steam clean an interior of the kitchen hood, and a height sensing assembly to sense a height of cookware seated on a cooktop surface below the second housing. The kitchen hood may be lengthened or shortened based on the sensed height of the cookware, and a speed of the fan and the height of the kitchen hood may be automatically adjusted based on detections by the air quality sensor assembly.

A substrate treating apparatus and a substrate transporting method wherein a platform is disposed on a first ID block, and a platform is placed on a second ID block. A currently-used carrier platform is provided only on the first ID block. Accordingly, a substrate is transported in both a forward path and a return path between the first ID block and a second treating block. The substrate is returned not to the first ID block but to the second ID block disposed between the two treating blocks in the return path.

An electric window cleaning device includes an operating portion and a wiping portion which are attracted to both sides of a glass of a window by magnets, and are free to move along the glass by virtue of balls. The wiping portion includes a power mechanism and a power supply device. The power mechanism includes an output shaft, a rotary disc and a duster removably fixed to the rotary disc. The power device includes a switch and a battery which are electrically connected to the power mechanism. When the power mechanism is turned on, the output shaft rotates the rotary disc and the duster to clean the outer surface of the glass, as an user moves the operating portion which is attracted to the inner surface of the glass, the wiping portion will also move along the outer surface of the glass to perform cleaning operation.

The present invention relates to an apparatus for cleaning a surface, in particular at solar collectors or photovoltaic installations. The apparatus has at least one cleaning head that comprises at least one cleaning member. The cleaning member is in particular a brush that can be set into rotation. The apparatus furthermore has a movement device for moving the cleaning head over at least a part of the surface to be cleaned. The movement device has a first movement unit movable in a first direction and a second movement unit. The cleaning head is movable transversely or obliquely to the first movement direction by means of the second movement unit along a guide means that is connected to the first movement unit. A control means that is arranged at the first and/or second movement units makes it possible to automatically move the first movement unit in dependence on a position of the second movement unit.
