An adjustable stroller wheel cleaning brush is a cleaning apparatus, that can access multiple locations of a wheel at the same time. Further, the device may also clean wheels of a wide variety of strollers and other similar sized wheels. To accomplish this, the apparatus is designed similar to an adjustable wrench, but with brushes on the wrench head's interior surfaces. More specifically, the wrench head may have an open jaw with an adjustable range enabling the cleaning apparatus to be used on wheels of varying dimensions. Further, the brushes of the apparatus would extend from multiple directions on the wrench head, thereby enabling the cleaning apparatus to clean multiple locations on the wheel. Thus, the stroller wheel cleaning brush is a user friendly, cost efficient, and width adjustable cleaning apparatus that enables efficient cleaning of stroller wheels.

A roller assembly for a mobile cleaning system for cleaning a work surface can include a drive shaft, a sheath, a bushing, and a bushing shroud. The drive shaft can be rotatable about a drive axis, and the drive shaft can include a driven end and an opposite bushing end. The sheath can be supported by the drive shaft and the sheath can be rotatable with the drive shaft. The sheath can include a shell engageable with the work surface. The bushing can be located about the bushing end of the drive shaft. The bushing shroud can be connected to the bushing. The sheath and the drive shaft can be together rotatable with respect to the bushing and the bushing shroud, the bushing shroud can include an outer portion defining a first radius of curvature and a recessed portion connected to the outer portion.

A handheld cleaning device includes a surface-moving portion and an upright portion. The surface-moving portion is in contact with a surface to be cleaned and is connected with the upright portion. The upright portion is configured to move the surface-moving portion in a case in which the surface-moving portion is in operation. The handheld cleaning device further includes a power battery configured to supply power to the handheld cleaning device. The surface-moving portion further includes at least two non-coaxial brushrolls configured to clean stains on the surface to be cleaned. The rotation speed of each brushroll is less than 3000 r/min.

An application element and an applicator comprising pluralities of said application elements on a molded support is provided for applying a product such as a cosmetic, a medicinal or a care product. At least one application element of the applicator includes a base portion and at least one thin projection. The thin projection includes at least one surface and wherein the at least one outer surface flushes with at least a portion of an outer surface of the base portion.

A surface cleaning implement for use with an elongated handle is provided. The implement includes a largely rectangular and asymmetric body region with rounded outer edges, largely planar upper and lower surfaces, and upstanding contact material coextensively disposed thereon. The body region is a largely flattened structure having a first and second leading edge corner, the corners comprising where the leading edge of the body region transitions to the side edges. The first corner comprises a large, sweeping radius for cleaning curving and open surfaces. The second corner comprises a sharp corner having a small radius, chamfered, protuberant, or largely square corner wherein overly elongated and stiffened contact material extends therefrom for contacting surfaces within corners or within confined areas. The head region includes a back end having a handle receiving sheath and suitable support therefor, wherein an elongated handle is attached thereto for use away from the user's person.

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 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.

The present invention provides a cleaning unit, comprising: a columnar body part having a rotation guide opening formed on the outer circumferential surface thereof; a shaft installed to reciprocate a predetermined distance in the longitudinal direction thereof in a hollow formed in the body part; a drive part that protrudes from the shaft in the radial direction thereof; a brush part that has one side installed on the outer circumferential surface of the body part along the longitudinal direction thereof and rotates on the basis of the one side as a rotation axis; and a driven part that extends from the brush part toward the drive part, passes through the rotation guide opening, and is inserted into a rotation guide groove formed in the drive part. The rotation guide groove extends at a predetermined angle with respect to the longitudinal direction of the shaft, and as the shaft reciprocates, the driven part is guided to rotate by means of the rotation guide groove, and the brush is rotated by means of the rotation of the driven part. The cleaning unit may include a robot cleaner or a cleaner operated by means of a user's operation.

A hand-held rotary tool includes a housing that encloses a motor having an output shaft. The tool includes a quick connect adaptor configured to connect an accessory to the output shaft. The adaptor includes a driver that is connected to the output shaft and rotates in concert with the output shaft. An outer surface of the driver has a first flat. The adaptor includes a receiver that includes a connector configured to detachably connect with the housing, and a torque transfer device configured to receive the driver. An inner surface of the torque transfer device includes a second flat that engages with the first flat in such a way that rotation of the driver results in rotation the torque transfer device relative to the connector. The adaptor includes an output device that supports the accessory and that is driven by the torque transfer device to move relative to the connector.

An obstacle crossing mechanism, adapted and arranged on a cleaning rack of a photovoltaic panel cleaning equipment configured to clean photovoltaic panel arrays is disclosed. The cleaning rack includes connecting rods detachably-connected, and fixed rods arranged on respective connecting rods. The obstacle crossing mechanism includes a moving rack and a fixed rack, in which moving rack is used for temporarily stopping photovoltaic panel cleaning equipment; and the fixed rack is located below the moving rack and the moving rack ascends or descends on the fixed rack. A telescopic mechanism is further provided with the obstacle crossing mechanism so that the two mechanisms together facilitates the photovoltaic panel cleaning equipment to travel from a photovoltaic panel array to reach another photovoltaic panel array during cleaning process of photovoltaic panels without requiring any human assistance, thus achieve total automation.
