A pool cleaning brush including an attachment portion and at least one brush assembly. The attachment portion is configured for removably connecting with a portion of a tail sweep hose of a swimming pool cleaner. The at least one brush assembly includes at least one cleaning element thereon. As the swimming pool cleaner automatically moves through the swimming pool to clean the same, the pool cleaning brush is carried along with the tail sweep hose and engages the swimming pool surface to agitate, brush and clean the same.

A diatomaceous earth filter cleaner for cleaning flex tubes attached to a tube sheet of a diatomaceous earth filter. The diatomaceous earth filter cleaner has a hollow tube, a blast jet housing, an inner diameter scrub brush, and a fitting at an end of the hollow tube for coupling a hose connected to a water supply. The hollow tube of the diatomaceous earth filter cleaner has a length with a first end and a second end for receiving a flex tube. The blast jet housing is attached to the first end of the hollow tube and comprises an angled lip and a restricted orifice formed by an inner circumference of the blast jet housing for receiving a flex tube. The inner diameter scrub brush is received within the inner circumference of the blast jet housing and has an orifice for cleaning an outer circumference of the flex tube.

A dental cleaning system includes a cylindrical body with a first portion and a second portion. A cleaning portion is positioned within the second portion and includes a cavity to enable the cleaning portion to at least partially enclose a dental implant device. The cylindrical body rotates such that the cleaning portion therein rotates to clean at least a portion of the dental implant device. A projection extends outwardly from a surface of the cleaning portion such that the projection is positioned within the cavity. The projection removes debris from at least a portion of the dental implant device when the cylindrical body rotates. A plurality of cleaning protrusions extend outwardly from a sidewall of the cavity such that the cleaning protrusions at least partially circumscribe the projection. The cleaning protrusions remove the debris from at least a portion of the dental implant device when the cylindrical body rotates.

A device for cleaning welds. The device comprises a bristles pad, the bristles pad being electrically conductive to deliver electrical current to a weld to be cleaned when the bristles pad is in physical contact with the weld. The device further includes a bristles pad support, the bristles pad support including an elongated body receiving the bristles pad and extending along the bristles pad, the elongated body including a first section and a second section attached to each other, the first section being separable from the second section to reduce a length of the bristles pad support.

A golf caddy tool assembly for fulfilling a variety of maintenance needs for the game of golf includes a handle that has a recess integrated therein. A ball marker is removably positionable in the recess for marking the location of a golf ball on a golf course. A divot fork is slidably coupled to the handle for lifting and repairing divots in the golf course. A brush is slidably coupled to the handle for scrubbing implements for playing golf.

According to one embodiment, a substrate treatment method of removing an upper end of a protrusion on a substrate is disclosed. An unevenness is formed on a surface of the substrate. The method can supply a first liquid on the surface of the substrate. The unevenness is formed on the surface. The method can form a protective layer. The protective layer covers the surface of the substrate from the first liquid supplied to the surface of the substrate. The method can supply a second liquid onto the protective layer. In addition the method can physically remove the protective layer which is on the upper end of the protrusion, and can bring the second liquid into contact with the upper end of the protrusion. The protective layer is removed from the upper end of the protrusion.

A wafer cleaning apparatus includes: a brush, configured to wash a surface to be cleaned of a wafer; a base for carrying the brush, the base having at least one conductive disk, a disk surface of the conductive disk being parallel to the surface to be cleaned, and the base being able to rotate around an axis of the base; and a magnetic field generation structure configured to emit, to the conductive disk, a magnetic field perpendicular to the disk surface of the conductive disk, so that an induced electric field is generated in the conductive disk during the rotation of the base. The quality of wafer cleaning and the yield of wafer products can be improved.

The brushing device contains a bundle of fibre rods (1), which are arranged parallel to one another, and a protective sleeve (2), which encloses the fibre rods. Once fibre rods (1) have become worn, the protective sleeve (2) is able to be axially adjusted, so that the free ends of the fibre rods (1) protrude beyond the protective sleeve (2) by a desired amount. A first component (4) connected to the fibre rods (1) and a further, second component (8) connected to the protective sleeve (2) are detachably connected to one another, in a non-positively locking manner, by a clamping mechanism (3, 5, 11).

A method and system used to periodically clean dirt and oils deposited through normal use from the grip of a golf club and renew it to a near new condition is disclosed. The system for cleaning and restoring a golf club grip of a golf club comprises a generally elongated housing having a hinge for splitting open the housing lengthwise wherein an interior of said housing defines retaining channels and a generally tapered and trapezoidal cleaning and restoring device defining an elongated centrally located ridge along a top of said device. In use, the device is placed into the housing by inserting the device ridge into the housing channel for holding the device during use wherein the housing defines a latch allowing the housing to close shut and hold a golf club grip in place during use with the device.

A floor cleaning device and method include mop head, including cleaning fibers, a corner brush coupled to an extendable member and extendable from a center of the mop head, and an inner handle including knob for engaging and disengaging a locking mechanism for locking corner brush in position. Floor cleaning device and method is useful for cleaning hard-to-reach areas of floors without the need for excessive bending or hand scrubbing.
