The set of holes may include a first sub-set of holes coinciding with holes associated with the first shaft and a second sub-set of holes coinciding with holes associated with the second shaft. Each of the first shaft and the second shaft may include a plurality of rib segments, each rib segment having a hole. The coupling member may be configured to couple with the first shaft via the first sub-set of holes and the plurality of holes associated with the first shaft. The coupling member may be further configured to couple with the second shaft via the second sub-set of holes and the plurality of holes associated with the second shaft.

A rotating brush for a vehicle washing system, comprising: i) a shaft (2) rotatable about a rotation axis (20) thereof; ii) a first annular support means (31) surrounding a first section (21) of said shaft (2) and comprising a first group (310) of longitudinal seats; said first support means (31) extending along the rotation axis (20) between a first and a second base (316, 317); let a first direction (318) of travel of the first group (310) of longitudinal seats be defined by the first towards the second base (316, 317), each of the longitudinal seats of the first group (310) comprising a first and a second end (312, 313); iii) a first set (41) of cleaning elements engageable in the first group (310) of longitudinal seats.

Embodiments include a vehicle side washer assembly, a shaft assembly, and horizontal cloth brush panels. The side washer assembly includes a retractable angled primary arm, a retractable secondary arm, a shaft assembly having an upright shaft, and horizontal cloth brush panels. The upright shaft is disposed through a shaft attachment region of each of the horizontal cloth brush panels. The shaft assembly includes an upright shaft including notches and protrusions, and retrofit discs each including a shaft opening that matches contours of the upright shaft. Each of the retrofit discs includes rotary notches. The horizontal cloth brush panels each include flat fingers, a contiguous central region, and a brush shaft opening cut to match contours of the upright shaft. The horizontal cloth brush panels rotate in a reverse rotation with a direction of travel of a vehicle, and can be mixed and matches with various sizes and shapes.

A surface cleaning apparatus can include a housing adapted to move across a surface to be cleaned, and an edge cleaning brush provided on the housing. The edge cleaning brush can include an attachment hub connectable with a drive coupling for rotating the brush, a cleaning implement configured to contact the surface to be cleaned, and a tensioner hub applying downward force onto the cleaning implement. Drive couplings for the edge cleaning brush are also disclosed, such as drive couplings including a worm and belt that are indirectly drive via a brushroll.

A plastic clip core assembly is disclosed for use in a rotary brush in a carwash. The plastic clip core is comprised of a plastic clip core, a plurality of longitudinal washing elements (“LWE”) and an equal plurality of plastic clips. The plastic clip core assembly is mated to a rotational hub, creating a rotary brush. The plastic clip core has a plurality of semi-cylindrical void cavities, each with an adjoining cylindrical void cavity. Each plastic clip has two parallel members, a first member and a second member. Each LWE has an upper edge, lower edge, free edge, and a cylindrical mount. A first member of a plastic clip fits into the cylindrical mount of the LWE and the semi-cylindrical void cavity. The second member of the plastic clip fits into the cylindrical void cavity, thus securing the LWE to the plastic clip core. The plastic clip core mates with the rotational hub in a no-slip condition.

A cleaner includes a cleaner main body, and a suction unit connected to the cleaner main body to suck air containing dust, and provided with a brush assembly brought into contact with a floor, wherein the brush assembly includes a rotating rod rotatable in one direction, a brush portion protruding from an outer circumferential surface of the rotating rod to rotate together with the rotating rod, and a blade erected at the rear of the brush portion in the one direction to be adjacent to the brush portion, and brought into contact with the brush portion during the rotation in the one direction, to prevent foreign substances from getting tangled in the brush portion. This configuration may prevent foreign substances such as hair and the like from being tangled in the brush portion during an operation of the cleaner.

A vehicle wash system includes a vehicle treatment area and an overhead frame portion supporting a pair of side brushes. The side brushes are configured to treat the lateral sides of the vehicle and may also treat the front and back of the vehicle. The side brushes are configured to pivot between a vertical position, an outwardly angled position, and inwardly angled position. The side brushes may travel along the side of the vehicle in both the vertical and pivoted orientations. The side brushes may make multiple passes along the side of the vehicle, and the side brushes may change orientation during or between passes to treat different segments of the vehicle. The side brushes may be actively pivoted or may pivot in response to contacting the vehicle when shifted laterally into contact with the vehicle.

A method of cleaning a surface includes steps of: urging brushes of a cleaning device against the surface; providing solvent to the surface via a solvent supply that passes through a housing of the cleaning device; rotating a drive gear about a drive-gear rotational axis to drive driven gears about corresponding driven-gear rotational axes inside the housing to rotate the brushes; and evacuating material from the surface via a vacuum tube, passing through the housing.

A carwash station receives a vehicle being conveyed in a direction of travel in a carwash having a ground pathway. The carwash station includes a frame supported by the ground pathway, a four-bar linkage attached to the frame and a side washing brush attached to the four-bar linkage and having an axis of rotation being perpendicular to the direction of travel and perpendicular to the ground pathway.
