A firearm cleaning device is disclosed herein. The device may include a housing comprising a grip portion, a motor housing portion opposite the grip portion, a neck portion disposed between the grip portion and the motor housing portion, and a slot disposed adjacent to the neck portion between the grip portion and the motor housing portion. The device also may include a motor disposed within the motor housing portion and a battery disposed within the grip portion. The battery may be electrically coupled to the motor. In addition, the device may include a shaft coupled to the motor and extending out of the motor housing portion, a detachable brush attachable to the shaft, and a motor switch disposed about the housing opposite the slot for activating the motor.

An apparatus for clearing around an associated stationary object includes a housing having a top wall, a side wall, and at least one opening extending through the side wall. At least one paddle member is mounted to and extends radially outward from an exterior surface of the housing. The paddle member is adapted to clear around the associated stationary object. The apparatus further includes a plurality of elongated cables mounted to a support that is selectively secured to an interior surface of the housing. The elongated cables are adapted to clean around the associated stationary object.

Modular and flexible interchangeable brush system to scrub a container. The brush system includes a handle having a first core and a second core. A sleeve is provided into which the first core and the second core are disposed. A flexible stem is removably connected to the first core of the handle. The flexible stern has at least one gap into which a resilient material is disposed. The location of the gap is at a bend location along a longitudinal axis of the handle. A first brush is operatively connected to the flexible stem, and a second brush is operatively connected to, and received within, the second core of the handle.

Among other things, there is disclosed a cylindrical device which is used to remove broken paintballs and other unwanted material from the barrel of a paintball marker or from other paintball equipment. Cylindrical cleaning devices currently known in the art are prone to separation and failure after use. The present disclosure includes structure such as barbs and/or openings, a snap-fit sleeve element, and/or one or more spacers to limit or prevent such failure. Structure for cleaning, including squeegee elements movable between an insertion configuration and a cleaning configuration, and other materials and configurations, are also disclosed.

A hole cleaning apparatus includes a member, a brush, and a vacuum source. The brush rotates around a longitudinal axis of the member, or translates in a direction which is substantially parallel to the longitudinal axis of the member. The vacuum source provides vacuum suction within the member.

A brush for a trailer hitch receiver. The brush includes a head shaped to conform to an interior channel of a trailer hitch receiver. This allows the brush to be used to clean the interior of a trailer hitch receiver, which is generally challenging to clean. In various embodiments, the head of the brush can be integral with the shaft. In other embodiments, the brush can include multiple interchangeable heads so that the cleaning tool can be used for multiple different types or sizes of trailer hitch receivers.

A firearm cleaning device is disclosed herein. The device may include a housing comprising a grip portion, a motor housing portion opposite the grip portion, a neck portion disposed between the grip portion and the motor housing portion, and a slot disposed adjacent to the neck portion between the grip portion and the motor housing portion. The device also may include a motor disposed within the motor housing portion and a battery disposed within the grip portion. The battery may be electrically coupled to the motor. In addition, the device may include a shaft coupled to the motor and extending out of the motor housing portion, a detachable brush attachable to the shaft, and a motor switch disposed about the housing opposite the slot for activating the motor.

An improved apparatus and methodologies of use for cleaning debris and contaminants from an interior surface or sidewall of a fluid-carrying conduit, such as a pipeline, are provided. More particularly, an apparatus and methodologies of use are provided, wherein the apparatus or pipeline pig operates bi-directionally and comprises counter-rotating cleaning elements that are operative to enhance removal of debris and contaminants from the pipeline.

A dust cleaning device for condenser of cooler is provided. Since the dust from outside is attached to the condenser due to ventilation and they become one of reasons for compressor failure, the device is configured to clean the heat exchange fin of the condenser periodically, in which a wire winch and a cleaning brush is connected to a driving axle of a driving motor such that the cleaning brush performs up-and-down motion and rotation with a power of the driving motor and cleans the heat exchange fin. In other structure, pinion and rack can be connected to the driving axle to perform the up-and-down motion. The cleaning brush is made of textile or unwoven fabric. Furthermore, the cleaning brush further includes a plurality of long brush portions protruding above the cleaning brush.

A cleaning brush structure is applicable for a washing machine, and the washing machine contains: a body in which an external drum is mounted, and the external drum accommodates an internal drum having a plurality of through orifices. Each of the plurality of through orifices accommodates a cleaning brush which includes a fixing element and a brushing element, and the fixing element has a conical face formed on a peripheral wall thereof, a small-diameter segment arranged on a first end thereof, and a large-diameter segment arranged on a second end thereof opposite to the first end of the fixing element. The brushing element is mounted on the small-diameter segment of the fixing element and has bristles inserted through said each through orifice so that the fixing element is fixed in said each through orifice of the internal drum.
