The present application provides a collapsible rotary electric cleaning brush, including a handle assembly, a drive assembly, a rotary assembly, and a cleaning brush head assembly. The handle assembly is connected to the drive assembly. A collapsible rotary assembly is provided at the lower part of the drive assembly. A detachable rotary cleaning brush head assembly is provided at the bottom of the rotary assembly. The beneficial effect of the present application is that: the automatic cleaning and the collapsible rotation function can be performed, the cleaning brush head can be offset with the cleaning area, and the cleaning can be performed automatically. The operation is simple and labor-saving. The present application is equipped with a variety of brush heads, which can be replaced according to different use scenarios and cleaning areas. The cleaning effect is the best, and the replacement is simple and convenient.

A vehicle wash component includes a hub portion with a first hub section and a second hub section. The first hub section includes a first distal end and a first proximate end opposite the first distal end. The first hub section defines a first axis of rotation. The second hub section includes a second distal end and a second proximate end opposite the second distal end. The second hub section defines a second axis of rotation. A connector device rotatably couples the first hub section to the second hub section. An actuator is in communication with the first hub section to effectuate movement of the first distal end between a retracted position and an extended position. In the retracted position, the first axis of rotation and the second axis of rotation are parallel. In the extended position, the first axis of rotation is at a non-90 angle with respect to the second axis of rotation.

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 electric cleaning brush includes a body, a brush neck and a brush head. A battery and a drive motor are disposed in the body, and the battery is configured to supply power to the drive motor. The brush neck is detachably connected to the body, a transmission shaft is rotatably mounted in the brush neck along a first direction, one end of the transmission shaft is connected to an output end of the drive motor, and the other end of the transmission shaft is provided with a driving gear. A driving gear is rotatably disposed in the brush neck and is configured to rotate axially in a second direction, the first direction intersects the second direction, and the driving gear meshes with the driven gear. The brush head is connected to the driven gear, and the drive motor can drive the brush head to rotate.

A surface cleaning brush is disclosed having a brush head with a plate, the plate having a plurality of apertures. U-Shaped bristle assemblies are inserted in the apertures and the base of the U-shaped bristle assemblies are secured with pins bent perpendicularly to the plate. The pins and bases of the bristle assemblies are then encased in a suitable hardened material to prevent their removal.

A grill cleaner with a handle and a head is provided. The handle includes a first end and a second end. The head is attached to the second end of the handle. The present invention further includes a grill brush including a block and a plurality of bristles protruding from the block. The grill brush is removeably attached to the head so that the grill brush may be easily replaced once the bristles have been worn down. A bristle wear indicator is attached to and protrudes from the head beyond the block and ending at a plane in between a first end of the plurality of bristles and a second end of the plurality of bristles. Therefore, once the bristles have worn down to the plane, the user is indicated to replace the grill brush.

An apparatus that cleans end surfaces of a substrate includes: a guide unit including a guide portion that has a channel, through which an end surface of a substrate passes, formed in a front surface thereof; and a brush with a front end whose position is controlled by a rear surface of the guide portion. The channel includes an opening that extends through the guide portion and the front end of the brush contacts an end surface of a substrate passing through the channel via the opening. The guide unit includes a concave portion in which at least the front end of the brush is housed and a suction hole that sucks dust from the concave portion.

Examples of self-serve cleaning device for automatically cleaning mats are disclosed. The mats can be cleaned easily and quickly within few minutes. The cleaning device comprises a compact insert washing module that comprises all of the washing and driving components that can easily and quickly be removed after a number of washing cycles and replaced with a new insert for refreshing and/or maintenance purposes.

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.
