Proposed is a washing brush in which a line of washing bristles is provided on a brush head by planting washing bristles in a straight line along the length direction of the head with a predetermined interval, and an end part of each of the washing bristles is bent at a certain angle toward the outside of the width direction of the head.

Components of automatic pool cleaners (APCs) are detailed. The components may include brushes configured to attach to blades of scrubbers of the APCs. The flexible brushes may rotate as their associated blades rotate and have fingers which flex so as to adduce contact between a to-be-cleaned pool or spa surface and bristles protruding outward from sides of the fingers.

A method and a device for cleaning espresso machines, wherein the device (10) comprises at least one annular or hollow-cylindrical bristle carrier element, wherein at least one groove-bristle element (18) for cleaning a portafilter groove (66) is arranged on an end face or lateral surface of the bristle carrier element, wherein the at least one groove-bristle element (18) projects from the end face or lateral surface, wherein at least a partial section of the at least one groove-bristle element (18) projects in the radial direction, and/or at least a partial section of the groove-bristle element (18) is concavely curved and/or in that at least one bristle element (17) is arranged on an inner lateral surface of the annular or hollow-cylindrical bristle carrier element.

The present disclosure relates to an apparatus and a method for wafer cleaning. The apparatus can include a wafer holder configured to hold a wafer; a cleaning nozzle configured to dispense a cleaning fluid onto a first surface (e.g., front surface) of the wafer; and a cleaning brush configured to clean a second surface (e.g., back surface) of the wafer. Using the cleaning fluid, the cleaning brush can clean the second surface of the wafer with a scrubbing motion and ultrasonic vibration.

According to one embodiment, there is provided a cleaning apparatus including a substrate cleaner and a member cleaner. The substrate cleaner has a substrate cleaning member placed over a first region to be opposite a substrate and a second region different from the first region. The member cleaner is placed adjacent to the second region.

Components of automatic pool cleaners (APCs) are detailed. The components may include brushes configured to attach to blades of scrubbers of the APCs. The flexible brushes may rotate as their associated blades rotate and have fingers which flex so as to adduce contact between a to-be-cleaned pool or spa surface and bristles protruding outward from sides of the fingers.

An electrolytic brush assembly including a handle assembly; a shroud extending from the handle assembly, the shroud having an aperture at a distal end thereof; and a brush connecting assembly for releasably connecting a brush to the handle assembly whereby the brush extends through the aperture of the shroud. The handle assembly includes an adjustment sub-assembly for selectively moving the brush connecting assembly and a brush connected thereto relative to the handle assembly and the aperture of the shroud.

An automatic washing apparatus for dogs and alike animals comprises a washing tub, a brushing plate and a horizontally movable carrier board on each side of the tub. Each brushing plate is attached to a vertically movable crank slider through horizontal extension arms. Each crank slider is motorized by a motor and situated on a carrier board. The carrier boards are mobilized by a low speed motor through pulleys, a timing belt, and wheels on rails. The movement is guided by a guiding rail. The tub includes a door and a drain on the floor and a wastewater compartment beneath the floor. The brushing plates and carrier boards are enclosed under two side covers. The apparatus further provides a water spraying system including spraying tubings, a water tank and a water pump.

A mobile trailer-cleaning system is a system that facilitates the cleaning of the exterior surfaces of a trailer. The system may include at least one brush assembly, a roof carriage, an agitation mechanism, and a steering assembly. The at least one brush assembly enables the cleaning of all the trailer's exterior surfaces including the rear of the trailer and any non-flat surfaces. The roof carriage serves as a guide to maintain the at least one brush assembly adjacent to the trailer's walls as the at least one brush assembly moves along the trailer. The roof carriage also prevents the at least one brush assembly from tipping over. The agitation mechanism eases the cleaning of the trailer's exterior surfaces by agitating the at least one brush assembly in predetermined modes of operation. The steering assembly enables the user to manually operate the at least one brush assembly during the cleaning process.
