An image forming apparatus includes a density sensing portion, a cleaning portion, and a control portion. The density sensing portion includes a substrate and a sensor package and outputs a sensing value related to a toner density of a toner image formed on an outer circumferential surface of an image carrier. The control portion performs control so that, when the cleaning portion performs cleaning of a sensing surface, a brush is moved to a cleaning position where the brush contacts the sensing surface. The control portion also performs control so that, when the cleaning portion does not perform the cleaning of the sensing surface, the brush is moved to a retracted position where the brush does not contact the sensor package and the substrate.

A deduster is comprised of two sets (pairs) of counter-rotating dedusting brushes in cooperation with a vacuum system for saw dust removal from wooden lumber. In addition to these features, the deduster may feature a separate, movable, top brush assembly that can be easily adjusted for different board thicknesses and raised up to allow for clearing board jams and for pass-through if boards were to be run without dedusting. This deduster apparatus is modular, thereby allowing it to be positioned over an existing machine or a lumber board unscrambler machine such as a lugged unscrambler machine. There is also a deduster for a board handling hopper.

The disclosure provides a jig for attaching and detaching a cleaning member, which facilitates attaching and detaching the cleaning member to and from a rotation device without holding the cleaning member directly by hand, even when there is no sufficient spacing around the cleaning member. The jig 100 for attaching and detaching a cleaning member 60 includes a pair of jig bodies 110 capable of clamping two ends 63 of a holder 62 of the cleaning member 60, and a connecting mechanism 120 that interlocks the movements of the pair of jig bodies 110 between a clamped state in which two ends 63 of the holder 62 are clamped and a non-clamped state in which the clamped state is released.

The present disclosure relates to an apparatus for cleaning a transfer plate and a method for cleaning the same. The apparatus for cleaning a transfer plate includes a rack, a cleaning tank, a cleaning roller, at least a part of a cylindrical surface of the cleaning roller is located inside the cleaning tank, and a transfer plate is provided on the cylindrical surface of the cleaning roller fixing mechanism for fixing a transfer plate wound around the cylindrical surface; protrusions are provided on the cylindrical surface, and a vacuum suction hole for sucking the transfer plate is provided on periphery of a protrusion; a friction cleaning device, and the friction cleaning device frictionally cleans the transfer plate through a relative movement between the cleaning roller and the friction cleaning device; a drive device configured to generate a relative movement between the cleaning roller and the friction cleaning device.

Buoyant, autonomous devices for actively scrubbing upstanding walls of swimming pools and spas at and nearby their waterlines are detailed. The devices may be configured to float on and travel along a surface of water of a pool and include at least one brush or scrubber adapted to contact pool walls. An electric motor may cause the scrubber to rotate about a shaft or axle, with frictional contact between the scrubber and the wall dislodging dirt and debris therefrom. In particular, if a scrubber is conically shaped and angled relative to the vertical direction, its rotating blades may lift water from the pool to hydrate dried debris stuck to the wall, thereby facilitating dislodging of the debris.

A rotary cleaning apparatus for underwater cleaning including a housing, a battery, a motor and a flexible hub system. The flexible hub system includes a toroidal brush system coupled to a circular centrifugal pump assembly. The flexible hub system includes a flexible hub allowing the flexible hub system to bend out of plane. When the flexible hub system is rotated underwater at a curved surface, the brush system cleans the surface while the suction of the centrifugal pump assembly flexes the flexible hub system to evenly contact the surface.

An upper spin chuck and a lower spin chuck are arranged in a vertical direction. In the lower spin chuck, a substrate holder sucks a center portion of a lower surface of a substrate, so that the substrate is held. In this state, a peripheral portion of the lower surface of the substrate rotated by a spin motor is cleaned by a brush of a first back surface cleaning mechanism. In the upper spin chuck, a plurality of chuck pins abut against an outer peripheral end of the substrate, so that the substrate is held. In this state, a region inward of the peripheral portion of the lower surface of the substrate rotated by the spin motor is cleaned by a brush of a second back surface cleaning mechanism. Receiving and transferring of the substrate are performed by a receiving transferring mechanism between the upper and the lower spin chucks.

The invention relates to a cleaning device for the dry cleaning of a tunnel, comprising a feeding device for feeding a flow of air to a surface being cleaned, wherein the feeding device has an exit opening, through which the flow of air emerges from the feeding device, and a removal device comprising at least one removal pipe with a free end with an opening for suctioning away direct or trash from the surface with the opening of the free end in a first direction. The feeding device is arranged such that the flow of air from the exit opening emerges from the feeding device in a second direction toward the opening of the free end of the removal pipe and impinges on the surface. The first direction is oriented at an angle between 45 and 80 to the second direction.

A rotary cleaning tool assembly for cleaning difficult to clean articles includes a housing that defines an interior space. A power module and a motor are coupled to the housing and are positioned in the interior space. The motor is operationally coupled to the power module. Each of a plurality of cleaning heads is selectively couplable to the housing so that the cleaning head is operationally coupled to the motor. The motor is positioned to rotate the cleaning head to clean an article.
