A long rod cleaning machine can prevent swinging due to partial contact and also perform local cleaning. A scrubber includes an electric motor, a tip tool including a cleaning portion, a head to which the tip tool is attachable, a rod, and a rotator between the head and the rod. The tip tool is attached in a manner movable with a driving force from the electric motor. The head includes a peripheral portion surrounding the cleaning portion and including a surface-cleaning lateral portion to be in contact with a cleaning target surface together with the cleaning portion. The rotator includes a rotation restrictor connecting the head to the rod in a manner rotatable relative to the rod about at least two axes. The rotation restrictor partially or fully restricts rotation of the head.

A tool and methods of removing films from bevel regions of wafers are disclosed. The bevel film removal tool includes an inner motor nested within an outer motor and a bevel brush secured to the outer motor. The bevel brush is adjustable radially outward to allow the wafer to be inserted in the bevel brush and to be secured to the inner motor. The bevel brush is adjustable radially inward to engage one or more sections of the bevel brush and to bring the bevel brush in contact with a bevel region of the wafer. Once engaged, a solution may be dispensed at the engaged sections of the bevel brush and the inner motor and the outer motor may be rotated such that the bevel brush is rotated against the wafer such that the bevel films of the wafer are both chemically and mechanically removed.

Presented is a multi-purpose cleaning tool for cleaning a group head of an espresso machine. The multi-purpose cleaning tool includes a top element and a bottom element. A ring brush and a centre textile disk cleaning pad are disposed on the first side of the top element. A central plate is positioned between the first side and the opposite second side of the bottom element. An inspection mirror is removably positioned below the central plate. A central hole is positioned substantially above the central plate wherein the central hole holds a hex shaft tool bit. Each of the top element and the bottom element includes a mating arrangement that enables the top element and the bottom element to be removably connected to each other.

A pool cleaning tool includes a brush head having an elongate frame and bristles extending therefrom; a first repositionable member attached to a first end of the elongate frame; and a second repositionable member attached to a second end of the elongate frame, wherein each of the first repositionable member and the second repositionable member includes: a forward end pivotally coupled to the elongate frame about a rotation axis; an upper surface configured to be rotatable about the rotation axis, the upper surface configured to force the bristles against a surface being cleaned as a result of the brush head being pushed through water in a direction perpendicular to a direction at which the bristles extend; and a locking mechanism configured to selectively retain the upper surface in each of a plurality of positions with respect to elongate frame.

A suction head of a vacuum cleaner including a housing having a suction port, a drum brush rotatably installed in the housing, a foreign substance removal pad provided on an inner surface of the housing to remove foreign substances wound on the drum brush by friction, and an anti-slip pad provided on the drum brush to prevent the foreign substances from slipping upon experiencing the friction with the foreign substance removal pad.

A reconfigurable brush includes an elongated brush head extending between brush-head first and second ends and a brush handle extending between handle proximate and distal ends. The brush-head first end is mounted to the handle distal end for rotation about a brush-head rotation axis between opposed first and second angular orientations and axial displacement along the brush-head rotation axis between opposed axial first and second positions. The first and second angular orientations are defined such that the brush-head second end is disposed, respectively, (i) rearwardly of the brush-head first end and the handle distal end and (ii) forwardly of the brush-head first end and the handle distal end. The axial first and second positions correspond to the handle being, respectively, (a) locked in one of the first and second angular orientations and (b) unlocked to allow rotation between the opposed first and second angular orientations.

A substrate-cleaning apparatus may include a tilting arm to which a roll brush and a motor are coupled, a support arm positioned on the tilting arm, a first spring and a second spring coupling the tilting arm to the support arm, a first air bag and a second air bag mounted between the tilting arm and the support arm, and a controller configured to adjust an internal pressure of each of the first air bag and the second air bag. The controller may adjust a difference in internal pressure between the first air bag and the second air bag to control the inclination of the roll brush, and may adjust the internal pressure of each of the first air bag and the second air bag to move the roll brush vertically.

Apparatus and associated methods relate to a fibrillous abrasive crevice cleaner (FACC). In an illustrative example, a fibrillous abrasive tip may be made of a continuous combination of steel wool and wire. For example, the FACC may include a twisted multistrand handle extending from a distal end to a proximal end along a longitudinal axis. The FACC may include a continuous fibrillous mass fixedly coupled about the distal end of the twisted multistrand handle, such that the fibrillous mass forms a knot distal to the proximal end of the twisted multistrand handle. For example, the FACC may include a proximal end of the fibrillous mass captured between the twisted multistrand handle. The formed knot around the distal end of the twisted multistranded handle and the fibrillous mass being entwined into the handle may, for example, advantageously resist decoupling of the fibrillous mass from the twisted multistrand handle.

A cleaner assembly includes a main body having a first end with a handle portion and a second end with a removable cleaner head; a pneumatic motor contained within said main body; an actuator operatively associated with said motor; a rotational shaft operatively associated with said motor and with a rotational cleaner head support; and a cleaner head removably attached to said rotational shaft.
